1
00:00:01,401 --> 00:00:07,204
The Colosseum... the Roman Empire
summed up in stone

2
00:00:10,210 --> 00:00:12,236
Never has such a civilized
culture

3
00:00:12,946 --> 00:00:14,847
poured so much of its wealth

4
00:00:14,915 --> 00:00:17,578
into engineering
spectacles of death

5
00:00:17,651 --> 00:00:20,746
for the entertainment
of its people

6
00:00:20,821 --> 00:00:22,949
In the morning you had
wild beast shows

7
00:00:23,023 --> 00:00:28,155
At around the lunchtime,
crucifixions

8
00:00:28,228 --> 00:00:30,197
In the afternoon,
the pièce de la résistance,

9
00:00:30,264 --> 00:00:33,200
two men, fighting to the death

10
00:00:36,470 --> 00:00:39,872
Ancient Roman accounts document
the Colosseum's repertoire

11
00:00:40,574 --> 00:00:43,271
in chilling detail

12
00:00:43,343 --> 00:00:46,780
They depict an orgy of
outrageous spectacles...

13
00:00:46,847 --> 00:00:51,717
Costumed gladiators cast in
battles to the death,

14
00:00:51,785 --> 00:00:56,621
exotic animals unleashed
on unsuspecting victims,

15
00:00:56,690 --> 00:01:01,993
even sea battles with thousands
of people killed

16
00:01:02,062 --> 00:01:04,964
Were the Romans as bloodthirsty
in their theatrics

17
00:01:05,032 --> 00:01:06,864
as ancient authors report?

18
00:01:10,203 --> 00:01:13,401
To investigate, a subterranean
archaeologist explores

19
00:01:14,107 --> 00:01:16,576
tunnels beneath the Colosseum

20
00:01:16,643 --> 00:01:21,377
to discover how it could be
flooded for naval battles

21
00:01:21,448 --> 00:01:25,283
A forensic scientist gives voice
to gladiators

22
00:01:25,352 --> 00:01:28,652
whose battle-bruised bones bear
witness to their own deaths

23
00:01:28,722 --> 00:01:31,658
We had in our hands
for the first time

24
00:01:31,725 --> 00:01:33,956
remains of real gladiators

25
00:01:35,529 --> 00:01:38,693
And an architect pieces together
clues of an elaborate system

26
00:01:39,399 --> 00:01:42,460
of ancient special effects
machines

27
00:01:42,569 --> 00:01:45,004
Then, with a team of engineers
and builders,

28
00:01:45,038 --> 00:01:46,904
they reconstruct it,

29
00:01:46,974 --> 00:01:52,777
and for the first time in
1,500 years release an animal

30
00:01:52,846 --> 00:01:53,870
into the Colosseum

31
00:01:55,949 --> 00:01:59,408
Now, can scientists and scholars
unlock the secrets

32
00:02:00,120 --> 00:02:03,249
of how and why
the Romans engineered

33
00:02:03,323 --> 00:02:06,157
such bloody spectacles?

34
00:02:06,226 --> 00:02:10,755
Right now on <i>NOVA,</i> "The
Colosseum: Roman Death Trap"

35
00:02:45,432 --> 00:02:49,199
If one building best symbolizes
the gore, glory

36
00:02:49,903 --> 00:02:53,431
and genius of the Romans,
it is the Colosseum

37
00:02:59,880 --> 00:03:03,282
It is a spectacle of design
and engineering,

38
00:03:03,984 --> 00:03:07,477
the biggest building
they ever constructed

39
00:03:08,655 --> 00:03:11,853
It spans nearly 2,000 feet
around,

40
00:03:12,559 --> 00:03:16,496
soars over 160 feet high,

41
00:03:16,563 --> 00:03:19,658
and soon after it opened in
the year 80, it was decorated

42
00:03:19,733 --> 00:03:21,827
in gleaming bronze shields

43
00:03:21,902 --> 00:03:27,842
and 16-foot statues
of gods and heroes

44
00:03:27,908 --> 00:03:32,107
To this day, the Colosseum
stands as a powerful landmark

45
00:03:32,179 --> 00:03:35,343
on the skyline of Rome

46
00:03:35,415 --> 00:03:38,476
When the Colosseum was built,
it had an enormous effect

47
00:03:38,552 --> 00:03:41,454
because of its size, status
and presence in Rome

48
00:03:44,991 --> 00:03:47,290
The echo of its 50,000
spectators

49
00:03:47,360 --> 00:03:52,697
cheering bloody theatrics
continues to haunt imaginations

50
00:03:54,434 --> 00:04:00,670
Gladiators fighting to
the death, mass crucifixions,

51
00:04:01,374 --> 00:04:04,606
elaborate animal hunts

52
00:04:04,678 --> 00:04:07,910
Over four centuries,
the Colosseum was witness

53
00:04:07,981 --> 00:04:12,385
to an estimated
million human deaths

54
00:04:12,452 --> 00:04:16,116
And with up to 11,000 animals
killed in a season,

55
00:04:16,189 --> 00:04:18,954
some species,
like the Balkan lion

56
00:04:19,025 --> 00:04:23,156
and a North African elephant,
were driven to extinction

57
00:04:24,765 --> 00:04:26,666
Yet the Colosseum was much more

58
00:04:27,367 --> 00:04:29,893
than a spectacular
slaughterhouse

59
00:04:29,970 --> 00:04:32,269
It was a carefully engineered
entertainment complex

60
00:04:32,339 --> 00:04:36,401
designed to reinforce
Roman world order

61
00:04:37,244 --> 00:04:39,543
Watching fighting

62
00:04:40,247 --> 00:04:41,738
on a regular basis
for entertainment

63
00:04:41,815 --> 00:04:46,014
gave the Romans a sense of who
they were and infused them

64
00:04:46,086 --> 00:04:47,884
with a kind of military ethos

65
00:04:47,954 --> 00:04:49,752
that was instrumental

66
00:04:49,823 --> 00:04:52,952
in creating and maintaining
the empire

67
00:04:54,194 --> 00:04:55,685
Ancient Roman authors,

68
00:04:56,396 --> 00:04:58,888
such as Martial
in his <i>Book of Spectacles,</i>

69
00:04:58,965 --> 00:05:04,768
describe how that world order
played out on the arena's stage

70
00:05:04,838 --> 00:05:08,900
They cast the emperor
as master illusionist

71
00:05:08,975 --> 00:05:13,811
On his command a menagerie of
ostriches, crocodiles, rhinos,

72
00:05:13,880 --> 00:05:17,248
bears and tigers
magically appear

73
00:05:17,317 --> 00:05:20,685
to be dispatched by hunters

74
00:05:20,754 --> 00:05:23,724
A condemned criminal
is dressed in wings

75
00:05:23,790 --> 00:05:29,161
and catapulted across the arena
to play out a Greek myth

76
00:05:29,229 --> 00:05:31,630
And fantastical sea battles
take place

77
00:05:31,698 --> 00:05:35,157
where thousands of prisoners
of war are either slaughtered

78
00:05:35,235 --> 00:05:39,138
or drowned

79
00:05:39,206 --> 00:05:44,543
Can these astonishing accounts
of elaborate executions be true?

80
00:05:44,611 --> 00:05:47,547
Or has the boundary
between history and myth

81
00:05:47,614 --> 00:05:50,379
been blurred over time?

82
00:05:55,188 --> 00:05:57,817
Most recently the Colosseum
was brought back to life

83
00:05:58,525 --> 00:06:01,222
in the film <i>Gladiator,</i>
where tigers spring

84
00:06:01,294 --> 00:06:04,526
from out of nowhere
to maul Russell Crowe

85
00:06:06,466 --> 00:06:08,662
But that's Hollywood effects

86
00:06:09,369 --> 00:06:13,431
The Romans were doing it
for real

87
00:06:14,541 --> 00:06:17,841
Parts of the movie <i>Gladiator</i>
are based on events portrayed

88
00:06:18,545 --> 00:06:21,947
in ancient texts and mosaics

89
00:06:22,015 --> 00:06:25,679
They depict gladiators locked
in combat

90
00:06:25,752 --> 00:06:29,621
and wild beasts mauling people

91
00:06:29,689 --> 00:06:31,248
But none of these accounts
describe

92
00:06:31,324 --> 00:06:34,852
how the Romans made these
animals magically appear

93
00:06:37,764 --> 00:06:40,666
Some scholars suspect the secret
may be hidden

94
00:06:41,368 --> 00:06:42,927
in the Colosseum's basement

95
00:06:49,876 --> 00:06:53,904
The hypogeum, the Greek word
for "underground,"

96
00:06:54,614 --> 00:06:57,812
is a maze of corridors
and collapsed walls

97
00:07:02,622 --> 00:07:05,319
Architect Heinz Beste thinks
that here,

98
00:07:06,026 --> 00:07:08,427
hidden from the spectators
above,

99
00:07:08,495 --> 00:07:10,987
is where the Romans engineered
their murderous magic

100
00:07:14,935 --> 00:07:17,166
We have to imagine
this being covered

101
00:07:17,237 --> 00:07:19,138
by the wooden arena floor above

102
00:07:19,205 --> 00:07:22,437
It was dark down here, lit only
by torches and small lamps

103
00:07:24,077 --> 00:07:29,641
Today, the arena floor has been
partially rebuilt for tourists

104
00:07:30,350 --> 00:07:33,650
The original was made of wood
and covered in sand

105
00:07:33,720 --> 00:07:35,552
to absorb blood

106
00:07:35,622 --> 00:07:41,926
The floor and all its wooden
supports are long gone,

107
00:07:42,028 --> 00:07:45,590
but etched into the walls
of the hypogeum

108
00:07:45,632 --> 00:07:49,296
Beste finds deep cuts
and grooves

109
00:07:49,369 --> 00:07:53,238
To decipher
these fossil-like remains,

110
00:07:53,306 --> 00:07:57,767
he drew every stone
on every wall

111
00:07:57,844 --> 00:08:01,337
After more than two years,
he began to make sense

112
00:08:01,414 --> 00:08:02,905
of the mysterious markings

113
00:08:05,752 --> 00:08:07,992
Through these drawings
it was possible

114
00:08:08,321 --> 00:08:12,258
to connect these clues
and turn the whole puzzle

115
00:08:12,325 --> 00:08:15,989
into a system
that can be explained

116
00:08:16,062 --> 00:08:22,969
Here he finds impressions made
by wooden beams

117
00:08:23,036 --> 00:08:26,302
And evenly spaced along
the floor are a series

118
00:08:26,373 --> 00:08:28,433
of round holes in concrete

119
00:08:30,443 --> 00:08:32,563
Here is another piece
of the puzzle

120
00:08:33,613 --> 00:08:36,879
This is a base for a capstan

121
00:08:37,584 --> 00:08:42,215
A capstan is a large round pole
that could be turned by workers

122
00:08:42,322 --> 00:08:43,415
to lift something

123
00:08:44,991 --> 00:08:46,459
Ah, interesting

124
00:08:49,229 --> 00:08:52,996
Up here we see an indentation
for a ramp

125
00:08:53,700 --> 00:08:56,192
Another mark reveals where
a ramp might have led

126
00:08:56,269 --> 00:08:57,396
to the arena

127
00:08:57,470 --> 00:09:01,202
In Beste's mind, the pieces
come together

128
00:09:02,375 --> 00:09:04,776
Support framing from the floor
of the hypogeum

129
00:09:05,478 --> 00:09:07,606
to the floor of the arena

130
00:09:08,481 --> 00:09:12,612
Halfway up, a horizontal beam
for workers to stand on

131
00:09:14,487 --> 00:09:17,423
A capstan with poles
for workers to turn

132
00:09:19,392 --> 00:09:22,760
A channel where a cage could fit

133
00:09:23,463 --> 00:09:27,366
And finally, a trap door that
could lower to become a ramp

134
00:09:27,434 --> 00:09:31,166
leading to the arena floor

135
00:09:31,237 --> 00:09:34,105
Together they form
what could be a device

136
00:09:34,174 --> 00:09:36,666
to lift and release animals

137
00:09:39,245 --> 00:09:41,237
I believe, given the evidence,

138
00:09:41,948 --> 00:09:44,247
there must have been an ancient
lift system here

139
00:09:46,586 --> 00:09:49,488
Throughout the hypogeum,
Beste finds evidence

140
00:09:50,190 --> 00:09:55,720
of ancient backstage machinery,
a total of 28 lifts

141
00:09:56,729 --> 00:09:59,198
Has Heinz Beste discovered
the secret

142
00:09:59,899 --> 00:10:03,301
to how the Romans made wild
animals magically appear

143
00:10:03,369 --> 00:10:07,238
in the arena?

144
00:10:07,307 --> 00:10:09,242
To find out,
he wants to construct

145
00:10:09,309 --> 00:10:12,006
a lift and trap door system...

146
00:10:12,078 --> 00:10:14,980
Install it right here
in the Colosseum

147
00:10:15,048 --> 00:10:18,485
and raise an animal into
the most famous amphitheater

148
00:10:18,551 --> 00:10:19,678
on earth

149
00:10:27,227 --> 00:10:29,958
But why did the Romans
build the Colosseum

150
00:10:30,663 --> 00:10:35,067
to stage these bloody
spectacles?

151
00:10:35,135 --> 00:10:38,435
Part of the answer is hiding
in plain sight

152
00:10:41,774 --> 00:10:44,710
For years, a cast aside stone
was used as a place

153
00:10:45,411 --> 00:10:49,439
for visitors to rest, its
importance completely unnoticed

154
00:10:51,618 --> 00:10:56,818
In the 1800s, an inscription
was discovered on its surface

155
00:10:57,524 --> 00:11:00,790
It ended up here
in the Colosseum museum,

156
00:11:00,860 --> 00:11:04,956
where it became, once again,
largely unnoticed

157
00:11:05,031 --> 00:11:10,026
But hidden beneath these 5th
century letters may be another,

158
00:11:10,103 --> 00:11:11,799
much earlier inscription

159
00:11:12,839 --> 00:11:15,365
Rosella Rea is director
of the Colosseum

160
00:11:16,075 --> 00:11:18,670
and one of the leading experts
on the building

161
00:11:18,745 --> 00:11:21,772
Mixed within
the engraved letters

162
00:11:21,848 --> 00:11:26,047
she sees a series
of strange holes

163
00:11:28,121 --> 00:11:30,666
You can see with the naked eye
that the holes are arranged

164
00:11:30,690 --> 00:11:32,352
in a regular pattern

165
00:11:32,425 --> 00:11:35,224
By studying their layout,

166
00:11:35,295 --> 00:11:38,322
it was found that the holes form
a series of letters

167
00:11:38,398 --> 00:11:43,132
The holes are where bronze
letters had once been fastened

168
00:11:43,203 --> 00:11:44,637
to the stone

169
00:11:44,704 --> 00:11:48,937
This was the hole
for the first letter

170
00:11:49,008 --> 00:11:50,670
The letter "I" for "imperator"

171
00:11:50,743 --> 00:11:53,941
Or "emperor"

172
00:11:54,013 --> 00:11:59,042
Connecting all the dots reveals
the original inscription

173
00:11:59,118 --> 00:12:02,646
The Emperor Vespasian ordered
this new amphitheater

174
00:12:02,722 --> 00:12:08,320
to be constructed from the booty

175
00:12:08,394 --> 00:12:13,833
Vespasian Flavius becomes
emperor in the year 69

176
00:12:13,900 --> 00:12:17,029
The following year he orders
construction of the Colosseum

177
00:12:17,103 --> 00:12:18,103
to begin

178
00:12:20,573 --> 00:12:26,035
The stone is the plaque
from its dedication

179
00:12:26,746 --> 00:12:31,150
And the letters spell out how
the Colosseum was paid for,

180
00:12:31,217 --> 00:12:33,049
with booty

181
00:12:33,119 --> 00:12:36,055
But booty from where?

182
00:12:37,523 --> 00:12:42,257
Vespasian's son left a clue
on the nearby Arch of Titus

183
00:12:42,962 --> 00:12:46,558
On it, Katherine Welch finds
depictions

184
00:12:46,633 --> 00:12:50,195
of Romans sacking
the Temple in Jerusalem

185
00:12:50,270 --> 00:12:54,173
One of the panels depicts
the menorah, the Torah,

186
00:12:54,240 --> 00:12:55,799
and the sacred table,

187
00:12:55,875 --> 00:12:58,902
carried by elite young Roman men

188
00:12:58,978 --> 00:13:03,040
This is quintessential
war booty,

189
00:13:03,116 --> 00:13:05,449
the things that meant the most

190
00:13:05,518 --> 00:13:07,851
to the people from whom
they were seized

191
00:13:10,290 --> 00:13:13,783
Following his son's conquest
of Judea in the year 70,

192
00:13:14,494 --> 00:13:18,522
Vespasian is rich
with gold and slaves

193
00:13:18,598 --> 00:13:22,000
He can build anything he wants

194
00:13:22,068 --> 00:13:24,663
So why the Colosseum?

195
00:13:24,737 --> 00:13:28,230
Vespasian needs a building
that makes a bold statement...

196
00:13:28,308 --> 00:13:30,607
That he, Vespasian Flavius,

197
00:13:30,677 --> 00:13:36,309
is nothing like the emperor
before him, the infamous Nero

198
00:13:36,382 --> 00:13:39,784
Emperor Nero's rule is marked
by extravagance

199
00:13:39,886 --> 00:13:42,720
and much of Rome burning

200
00:13:42,755 --> 00:13:46,317
He confiscates land and builds
a pleasure palace

201
00:13:46,392 --> 00:13:50,420
with gardens and a manmade lake

202
00:13:50,496 --> 00:13:54,263
Nero is driven from the throne,
commits suicide,

203
00:13:54,334 --> 00:13:57,930
and Rome is engulfed
in civil war

204
00:13:58,004 --> 00:14:01,634
After a ghastly year of civil
war and the suicide of Nero,

205
00:14:01,708 --> 00:14:05,076
Vespasian did everything
in his living power

206
00:14:05,144 --> 00:14:06,942
to ingratiate himself
with the Senate

207
00:14:07,013 --> 00:14:09,505
and consolidate
his personal power

208
00:14:09,582 --> 00:14:14,384
After fighting his way to the
throne, Vespasian casts himself

209
00:14:14,454 --> 00:14:17,219
as the anti-Nero

210
00:14:17,290 --> 00:14:20,556
He buries Nero's palace,
fills in his lake

211
00:14:20,626 --> 00:14:23,790
and on top builds the opposite
of a pleasure garden...

212
00:14:23,863 --> 00:14:28,597
A public building
for blood sports

213
00:14:28,668 --> 00:14:32,662
In building the largest, most
expensive building in Rome,

214
00:14:32,739 --> 00:14:35,072
a building for popular
entertainment,

215
00:14:35,141 --> 00:14:40,876
it celebrated military power
and put it into a frightening,

216
00:14:40,980 --> 00:14:44,246
exciting, chastening context

217
00:14:44,283 --> 00:14:49,517
The Colosseum is the perfect
symbol for how Vespasian

218
00:14:49,589 --> 00:14:51,251
and Rome came to power

219
00:14:54,260 --> 00:14:57,196
And to enhance the blood sports,
Vespasian builds in

220
00:14:57,897 --> 00:15:05,897
some deadly surprises, releasing
wild animals into the arena

221
00:15:07,039 --> 00:15:10,476
But reconstructing the lift
that could have done this

222
00:15:10,543 --> 00:15:12,205
is an audacious plan

223
00:15:12,278 --> 00:15:16,045
If Heinz Beste is to succeed,
he'll need to find

224
00:15:16,115 --> 00:15:17,845
an ally on the inside

225
00:15:19,819 --> 00:15:23,051
Umberto Baruffaldi is
an engineer, inventor

226
00:15:23,756 --> 00:15:26,726
and GoPro enthusiast

227
00:15:26,793 --> 00:15:30,855
He too is captivated by how
the Romans released wild animals

228
00:15:30,930 --> 00:15:32,523
into the arena

229
00:15:32,598 --> 00:15:34,362
Umberto also happens to be

230
00:15:34,434 --> 00:15:36,926
director of health and safety
for the Colosseum

231
00:15:37,003 --> 00:15:40,701
Beste shares his drawings
with Umberto

232
00:15:40,807 --> 00:15:43,606
The drawing is beautiful,

233
00:15:43,643 --> 00:15:46,704
but how are we going
to make it work?

234
00:15:46,779 --> 00:15:49,544
Beste's drawings provide
a skeleton of the system,

235
00:15:49,615 --> 00:15:53,416
but it's not clear how the lift
actually works

236
00:15:53,486 --> 00:15:58,049
Umberto brings in structural
engineer Giovanni Squillacioti

237
00:15:58,124 --> 00:16:00,923
and material engineer
Flavia Campanelli

238
00:16:00,993 --> 00:16:04,623
We have to create a system
of pulleys and counterweights

239
00:16:04,697 --> 00:16:07,394
that works perfectly
and synchronizes

240
00:16:07,467 --> 00:16:11,404
Giovanni translates Beste's
two-dimensional drawing

241
00:16:11,471 --> 00:16:14,339
into a three-dimensional
computer model

242
00:16:18,845 --> 00:16:22,213
The trap door is one
of the big challenges

243
00:16:22,915 --> 00:16:26,044
On one hand it has to open

244
00:16:26,118 --> 00:16:27,643
to release the animal
into the arena

245
00:16:32,625 --> 00:16:36,619
But when it's closed,
it has to support the weight

246
00:16:37,330 --> 00:16:39,424
of gladiators, charioteers

247
00:16:39,532 --> 00:16:41,592
and heavy animals trampling
on it above

248
00:16:42,668 --> 00:16:46,036
Giovanni puts the pieces
together and connects them

249
00:16:46,739 --> 00:16:51,541
in his computer model with
pulleys, ropes and hinges

250
00:16:51,611 --> 00:16:53,842
<i>Perfecto.</i>

251
00:16:53,913 --> 00:16:57,350
Then, based on Giovanni's
3D wizardry,

252
00:16:57,416 --> 00:17:00,250
Heinz and Umberto build
a scale model

253
00:17:09,161 --> 00:17:12,188
At the heart of the system is
the capstan,

254
00:17:12,899 --> 00:17:15,733
a large central pole

255
00:17:15,801 --> 00:17:21,297
As this is turned,
it wraps a rope around it

256
00:17:21,374 --> 00:17:24,208
The animal is placed
in this cage

257
00:17:24,277 --> 00:17:28,078
It's connected to the capstan
through a series of pulleys,

258
00:17:28,147 --> 00:17:32,016
so as the capstan is turned,
the cage rises

259
00:17:34,353 --> 00:17:39,815
Two large hinged arms support
the trap door when it's closed,

260
00:17:40,526 --> 00:17:42,358
and then swing down to open it

261
00:17:45,131 --> 00:17:49,728
As the cage rises,
the door automatically opens,

262
00:17:50,436 --> 00:17:53,133
releasing the animal
onto the ramp

263
00:17:57,510 --> 00:18:01,311
The model is essential to
experimental work of any kind,

264
00:18:02,014 --> 00:18:04,313
because it is the model that
allows you to understand

265
00:18:04,383 --> 00:18:05,383
all the mechanics

266
00:18:06,686 --> 00:18:09,383
And building the lift
and trap door system

267
00:18:10,089 --> 00:18:14,720
will provide a window into
a uniquely Roman pastime,

268
00:18:14,794 --> 00:18:20,256
in a uniquely Roman building,
the amphitheater

269
00:18:24,837 --> 00:18:27,739
Mark Wilson Jones is an
architect with an expertise

270
00:18:28,441 --> 00:18:31,104
in Greek and Roman buildings

271
00:18:31,177 --> 00:18:33,078
He's here in Arles
in southern France,

272
00:18:33,145 --> 00:18:35,546
at an amphitheater constructed
about 20 years

273
00:18:35,615 --> 00:18:37,584
after the Colosseum

274
00:18:37,650 --> 00:18:39,828
In general, the Romans took
their building forms

275
00:18:39,852 --> 00:18:40,945
from the Greeks

276
00:18:40,987 --> 00:18:43,252
But this is not the case
for the amphitheater

277
00:18:43,322 --> 00:18:45,882
The amphitheater was a definite
Roman invention

278
00:18:45,958 --> 00:18:49,588
And they created it for
the special circumstances

279
00:18:49,662 --> 00:18:52,393
of gladiatorial fights

280
00:18:52,465 --> 00:18:57,028
<i>Amphi</i> means "double" in Greek,

281
00:18:57,103 --> 00:19:01,302
and <i>amphitheater</i> translates
as "double theater"

282
00:19:01,374 --> 00:19:05,539
But if a Greek theater were just
doubled, it would be round

283
00:19:05,611 --> 00:19:09,207
The Roman amphitheater is
actually a stretched circle,

284
00:19:09,281 --> 00:19:10,374
or an oval

285
00:19:12,018 --> 00:19:14,578
Wilson Jones believes
the Romans' innovation

286
00:19:15,287 --> 00:19:18,257
of the oval shape may be
a direct result

287
00:19:18,324 --> 00:19:24,161
of the building's function...
A place for gladiator combat

288
00:19:25,064 --> 00:19:26,784
Most buildings are rectangular

289
00:19:27,166 --> 00:19:28,293
And that's a bad thing

290
00:19:28,367 --> 00:19:30,167
because you can get action stuck
in the corner

291
00:19:30,236 --> 00:19:38,236
If a gladiator gets stuck in a
corner, he gets killed quickly

292
00:19:38,344 --> 00:19:41,371
The oval shape helps
prolong the action

293
00:19:41,447 --> 00:19:43,973
for maximum entertainment value

294
00:19:44,050 --> 00:19:48,784
So this shape has
a dynamic quality, no corners

295
00:19:48,854 --> 00:19:50,618
Everything's smooth

296
00:19:50,690 --> 00:19:53,216
So the action can move around

297
00:19:53,292 --> 00:19:56,854
And I think that really helps it
maintain its excitement

298
00:19:59,231 --> 00:20:04,260
An amphitheater for gladiator
combat is uniquely Roman

299
00:20:04,970 --> 00:20:07,337
in form and function...

300
00:20:07,406 --> 00:20:10,433
Exactly the symbol
Emperor Vespasian needs

301
00:20:10,509 --> 00:20:15,174
to project his power
and inspire Roman pride

302
00:20:18,884 --> 00:20:21,564
There's this strong connection
between the unique shape

303
00:20:21,687 --> 00:20:25,590
of the amphitheater and
gladiatorial performances,

304
00:20:25,658 --> 00:20:29,993
the link with the military,
the conquest of empire

305
00:20:30,062 --> 00:20:33,055
The great crowds of 50,000 that
came together in the Colosseum

306
00:20:33,132 --> 00:20:36,261
were celebrating all of that

307
00:20:36,335 --> 00:20:39,499
It's really a sort of great day
out to feel a Roman citizen

308
00:20:39,605 --> 00:20:41,164
and feel at the center
of the world

309
00:20:50,049 --> 00:20:52,780
In a forest northeast of Rome,

310
00:20:53,486 --> 00:20:55,921
Umberto is in search
of the perfect tree

311
00:20:55,988 --> 00:20:56,988
for making the lift

312
00:20:59,425 --> 00:21:02,259
The tree will be used for one
of the key parts of the lift,

313
00:21:02,962 --> 00:21:04,487
the capstan

314
00:21:09,969 --> 00:21:13,838
To fell the tree, the team
uses the same tools

315
00:21:14,540 --> 00:21:21,947
as the ancient Romans: the ax,
the two-man saw and a wedge

316
00:21:23,215 --> 00:21:27,277
Carmelo Malacrino, an expert
on ancient Roman building,

317
00:21:27,987 --> 00:21:32,049
knows what tools to use from
images on the Trajan Column,

318
00:21:32,124 --> 00:21:36,653
erected just 30 years after
the opening of the Colosseum

319
00:21:36,729 --> 00:21:41,565
This column shows a fantastic
series of tree cutting

320
00:21:41,667 --> 00:21:43,761
It depicts the deforestation
process

321
00:21:43,803 --> 00:21:46,830
for constructing new roads and
the creation of campsites

322
00:21:46,906 --> 00:21:49,705
as part of a military campaign

323
00:21:51,243 --> 00:21:53,371
After an hour of chopping
and sawing,

324
00:21:54,079 --> 00:21:57,709
the tree comes crashing down

325
00:22:08,027 --> 00:22:15,560
Now, the tree begins its
transformation into the capstan

326
00:22:16,268 --> 00:22:17,759
But Umberto leaves a little bark

327
00:22:17,837 --> 00:22:20,204
as a reminder of where
it came from

328
00:22:21,373 --> 00:22:24,901
The team uses
their scale model as a guide

329
00:22:25,611 --> 00:22:28,638
for building the lift

330
00:22:28,714 --> 00:22:30,992
The move from the model
to the real thing

331
00:22:31,016 --> 00:22:32,644
was a little traumatic

332
00:22:32,718 --> 00:22:36,780
Working in a dimension
four times bigger

333
00:22:36,856 --> 00:22:38,984
really amplifies the problems

334
00:22:40,893 --> 00:22:44,660
The cage itself will weigh
over 800 pounds

335
00:22:45,364 --> 00:22:49,529
It needs to be strong to keep
wild animals inside

336
00:22:50,903 --> 00:22:54,772
We have to pay attention
to the sturdiness of the cage

337
00:22:55,474 --> 00:22:57,636
since it's supposed to hold
lions and tigers

338
00:22:59,612 --> 00:23:03,549
Seeing the lift at full scale,
Umberto starts to have

339
00:23:04,250 --> 00:23:07,015
some concerns

340
00:23:07,086 --> 00:23:09,297
The most difficult part will be
getting the lift in

341
00:23:09,321 --> 00:23:10,653
without touching the Colosseum

342
00:23:10,723 --> 00:23:12,589
Because if we damage
the Colosseum,

343
00:23:12,658 --> 00:23:14,388
I'll be chased
out of the Colosseum

344
00:23:20,900 --> 00:23:24,860
Today, the Colosseum is
a majestic ruin

345
00:23:25,571 --> 00:23:26,800
Over the centuries,

346
00:23:26,872 --> 00:23:31,105
everything of value was stripped
from its walls

347
00:23:31,176 --> 00:23:34,340
But coins minted for its opening

348
00:23:34,413 --> 00:23:35,813
and carvings on tombs

349
00:23:35,881 --> 00:23:39,682
show how the Colosseum was
likely decorated

350
00:23:39,785 --> 00:23:46,453
In its arches stood 160 bronze
statues 16 feet tall,

351
00:23:46,492 --> 00:23:49,428
representing gods and heroes
the Romans borrow

352
00:23:49,495 --> 00:23:51,464
from the Greek pantheon

353
00:23:51,530 --> 00:23:56,195
At its top layer were
gleaming bronze discs

354
00:23:56,268 --> 00:23:59,363
symbolizing captured shields

355
00:23:59,438 --> 00:24:02,067
Finally, framing the arches

356
00:24:02,141 --> 00:24:06,579
were columns of various
architectural orders:

357
00:24:06,645 --> 00:24:09,706
Greek capitals on the upper
three layers,

358
00:24:09,782 --> 00:24:11,944
but on the street level
are Roman capitals

359
00:24:13,452 --> 00:24:16,320
Vespasian is giving the people,
the plebs Romana,

360
00:24:17,022 --> 00:24:23,053
exactly what they want...
Greek orders, Greek statues,

361
00:24:23,128 --> 00:24:24,858
but all with a Roman twist

362
00:24:24,930 --> 00:24:28,264
and pressed into the service
of the conquering Roman state

363
00:24:34,239 --> 00:24:36,970
The Colosseum's decorations
amplify the message

364
00:24:37,676 --> 00:24:41,807
of the building's
monumental scale:

365
00:24:41,914 --> 00:24:44,884
We Romans love
Greek art and culture,

366
00:24:44,917 --> 00:24:47,250
but we have surpassed them

367
00:24:47,319 --> 00:24:51,017
Rome is the new superpower

368
00:24:55,461 --> 00:24:57,020
As a final touch,

369
00:24:57,730 --> 00:25:00,427
there was a bronze chariot above
the entry arch

370
00:25:00,499 --> 00:25:02,092
on the north side,

371
00:25:02,167 --> 00:25:04,466
where the emperor could make
his grand entrance

372
00:25:06,739 --> 00:25:10,938
But Vespasian will never walk
beneath it

373
00:25:11,643 --> 00:25:17,583
He dies just months before
the Colosseum is completed

374
00:25:17,649 --> 00:25:20,744
He does leave a lasting legacy
though:

375
00:25:20,819 --> 00:25:26,156
the largest building in Rome
and an imperial dynasty

376
00:25:26,225 --> 00:25:28,751
For the first time
in Roman history,

377
00:25:28,827 --> 00:25:33,765
an emperor is directly succeeded
by his natural son

378
00:25:33,832 --> 00:25:38,463
In the year 80, Titus holds
the inaugural games

379
00:25:38,537 --> 00:25:40,768
in honor of his father

380
00:25:45,544 --> 00:25:48,981
Roman author Martial
in his "Liber Spectaculorum"...

381
00:25:49,681 --> 00:25:55,211
The <i>Book of Spectacles...</i>
Describes the inaugural games

382
00:25:55,287 --> 00:26:01,488
A hundred days of crucifixions,
wild beast shows,

383
00:26:01,560 --> 00:26:05,088
gladiator combat
and, for the first time,

384
00:26:05,164 --> 00:26:07,326
the acting out of Greek myths

385
00:26:07,399 --> 00:26:11,461
with elaborate scenery
and actual death

386
00:26:11,537 --> 00:26:13,648
What happened with the
inauguration of the Colosseum

387
00:26:13,672 --> 00:26:16,232
is that these Greek
mythological executions

388
00:26:16,308 --> 00:26:19,608
entered the arena repertoire

389
00:26:19,678 --> 00:26:22,375
Except in the theater
they were bloodless,

390
00:26:22,448 --> 00:26:23,848
they were just actors

391
00:26:23,916 --> 00:26:26,943
In the amphitheater they were
condemned criminals

392
00:26:27,019 --> 00:26:32,151
who were forced to dress up
as Greek mythological characters

393
00:26:32,224 --> 00:26:34,318
and killed in the Colosseum

394
00:26:35,160 --> 00:26:38,028
The Romans would reenact
well-known Greek myths,

395
00:26:38,730 --> 00:26:43,566
such as Icarus flying too close
to the sun and falling to earth

396
00:26:43,635 --> 00:26:47,538
But in the Colosseum, there was
a gruesome twist

397
00:26:47,606 --> 00:26:50,542
The criminal playing Icarus
would be catapulted

398
00:26:50,609 --> 00:26:53,602
across the arena to his death

399
00:26:53,679 --> 00:26:54,679
This is not a myth

400
00:26:54,713 --> 00:26:55,713
It's real

401
00:26:57,015 --> 00:27:00,110
Martial goes on to describe
a mass execution

402
00:27:00,819 --> 00:27:06,588
so cruelly choreographed it
surpasses even Roman standards

403
00:27:06,658 --> 00:27:10,720
Naumachiae... mock sea battles
where ships are sunk

404
00:27:10,796 --> 00:27:13,095
with hundreds of prisoners
on board

405
00:27:16,034 --> 00:27:19,596
What astonishes Martial is not
the mass murder by drowning,

406
00:27:20,305 --> 00:27:23,707
but rather how it was pulled off

407
00:27:23,775 --> 00:27:26,267
How could the Colosseum be
flooded for sea battles

408
00:27:26,345 --> 00:27:29,179
in the morning, then drained
quickly enough

409
00:27:29,248 --> 00:27:32,776
for gladiator combat
in the afternoon?

410
00:27:40,025 --> 00:27:43,757
The Romans were masters
of moving water

411
00:27:44,463 --> 00:27:48,161
A network of 11 aqueducts
carried clean water to Rome

412
00:27:48,233 --> 00:27:53,103
from mountain springs,
some over 50 miles away

413
00:27:53,172 --> 00:27:58,042
The aqueducts provide the means
to get water into the Colosseum

414
00:27:58,110 --> 00:28:01,274
And new discoveries are
revealing a system

415
00:28:01,346 --> 00:28:03,781
to get water out

416
00:28:10,222 --> 00:28:14,318
Adriano Morabito, director
of Subterranean Rome,

417
00:28:15,027 --> 00:28:19,465
has spent ten years mapping the
city's underground water system

418
00:28:19,531 --> 00:28:23,024
One day while surveying
for a new metro line,

419
00:28:23,101 --> 00:28:26,196
he took an unexpected turn

420
00:28:26,271 --> 00:28:30,174
We were mapping all the sewage
system and suddenly we went

421
00:28:30,242 --> 00:28:33,610
into an older drainage system
and we saw light at the end

422
00:28:35,681 --> 00:28:38,617
To his great surprise, the light
at the end of the tunnel

423
00:28:39,318 --> 00:28:42,914
was the Colosseum

424
00:28:43,021 --> 00:28:48,426
Morabito had stumbled into an
ancient drain or "collector"

425
00:28:48,460 --> 00:28:52,761
This is the only collector
still working today

426
00:28:52,831 --> 00:28:57,235
In ancient times we had all
four collectors getting rid

427
00:28:57,302 --> 00:28:58,998
of the water out of the monument

428
00:28:59,071 --> 00:29:03,736
Beneath the arena, Morabito
finds evidence of four drains

429
00:29:03,809 --> 00:29:07,041
that emptied water
from the Colosseum

430
00:29:07,112 --> 00:29:10,014
And climbing to the top
of the hypogeum,

431
00:29:10,082 --> 00:29:15,316
Morabito finds 40 channels
that may have fed water in

432
00:29:15,387 --> 00:29:16,898
Some archaeologists speculate

433
00:29:16,922 --> 00:29:21,917
that this could have been used
to flood the arena

434
00:29:21,994 --> 00:29:24,429
Morabito believes
the 40 input channels

435
00:29:24,496 --> 00:29:27,091
and four drains
provide the plumbing

436
00:29:27,165 --> 00:29:29,725
to stage naval battles

437
00:29:29,801 --> 00:29:32,862
To put his theory to the test,

438
00:29:32,938 --> 00:29:36,306
he investigates how much water
the Romans would need

439
00:29:36,375 --> 00:29:40,540
to flood the arena

440
00:29:40,612 --> 00:29:45,141
He finds four passageways
leading into the hypogeum,

441
00:29:45,217 --> 00:29:47,516
wide enough to launch
flat-bottomed boats

442
00:29:47,586 --> 00:29:50,385
into the arena

443
00:29:50,455 --> 00:29:51,766
When the arena was flooded

444
00:29:51,790 --> 00:29:53,759
the water was coming in here

445
00:29:53,825 --> 00:29:57,819
and then the boats were starting
floating up to this level,

446
00:29:57,896 --> 00:29:59,865
because otherwise the water
would have gone

447
00:29:59,931 --> 00:30:02,230
into other rooms

448
00:30:02,301 --> 00:30:05,135
Morabito reasons the water could
have been no higher

449
00:30:05,203 --> 00:30:07,934
than about five feet or it would
spill over

450
00:30:08,006 --> 00:30:10,498
into other areas
of the Colosseum

451
00:30:10,575 --> 00:30:14,910
Multiplying that depth
by the area of the arena,

452
00:30:14,980 --> 00:30:17,848
he calculates, with
the floor removed it can hold

453
00:30:17,916 --> 00:30:20,681
a million and a quarter
gallons of water,

454
00:30:20,752 --> 00:30:24,746
equal to about two Olympic
swimming pools

455
00:30:24,823 --> 00:30:28,316
But can the drains empty
that much water fast enough

456
00:30:28,393 --> 00:30:32,387
to stage sea battles
and gladiator fights

457
00:30:32,464 --> 00:30:37,732
all in one day, as author
Martial describes?

458
00:30:39,838 --> 00:30:42,672
One night a thunderstorm puts
Morabito's theory

459
00:30:42,708 --> 00:30:48,113
and the surviving drain
to the test

460
00:30:49,781 --> 00:30:54,242
The storm dumps 800,000 gallons
of water into the Colosseum,

461
00:30:54,953 --> 00:30:58,947
filling the hypogeum halfway

462
00:31:02,060 --> 00:31:05,997
That rainwater,
with just one drain,

463
00:31:06,698 --> 00:31:10,692
empties in under two hours

464
00:31:10,769 --> 00:31:14,103
Morabito calculates that with
all four drains working,

465
00:31:14,172 --> 00:31:18,075
the Colosseum could be emptied
in less than an hour

466
00:31:18,143 --> 00:31:20,374
It was therefore
technically possible

467
00:31:20,445 --> 00:31:23,745
for the emperor's engineers
to flood the arena

468
00:31:23,815 --> 00:31:28,253
for its opening games

469
00:31:28,320 --> 00:31:32,223
Morabito believes the Romans had
the plumbing and enough water

470
00:31:32,290 --> 00:31:35,727
to stage mock sea battles
in the Colosseum,

471
00:31:35,794 --> 00:31:39,162
just as the ancient texts claim

472
00:31:42,634 --> 00:31:46,503
But could they really lift
animals into the arena?

473
00:31:51,777 --> 00:31:54,906
After months of constructing
the lift and trap door system

474
00:31:55,614 --> 00:32:00,643
in the workshop outside of Rome,
today the pieces finally arrive

475
00:32:01,486 --> 00:32:04,388
The 440-pound trap door,

476
00:32:05,090 --> 00:32:10,859
the 2,000-pound frame
and nearly 1,000-pound cage

477
00:32:10,929 --> 00:32:14,923
And the capstan,
weighing in at 500 pounds

478
00:32:15,000 --> 00:32:18,164
Originally the pieces were built

479
00:32:18,236 --> 00:32:21,764
right into the walls
of the hypogeum

480
00:32:21,840 --> 00:32:25,038
But today those fragile walls

481
00:32:25,110 --> 00:32:28,080
are a part of a protected
World Heritage site

482
00:32:28,146 --> 00:32:30,877
that can't be altered

483
00:32:30,949 --> 00:32:36,047
So their idea is to pre-assemble
the lift outside the Colosseum

484
00:32:36,121 --> 00:32:42,027
and then drop it into place as
one self-contained unit

485
00:32:43,462 --> 00:32:46,398
Assembling the lift is a tricky
process,

486
00:32:47,098 --> 00:32:48,566
almost as tricky as the design

487
00:32:48,633 --> 00:32:49,931
It's big and bulky

488
00:32:50,001 --> 00:32:52,061
And then lowering
into the Colosseum

489
00:32:52,137 --> 00:32:53,696
is the most difficult part

490
00:32:53,772 --> 00:32:58,403
Umberto has hired
a 200-foot crane

491
00:32:58,477 --> 00:33:00,776
for this delicate operation

492
00:33:00,846 --> 00:33:05,409
Giovanni Cirillo is
behind the controls

493
00:33:05,484 --> 00:33:07,361
The only issue today is the wind

494
00:33:07,385 --> 00:33:09,945
And the later it gets in the
afternoon the windier it gets

495
00:33:10,021 --> 00:33:13,651
That might shake the structure
and make my job less exact

496
00:33:16,228 --> 00:33:20,188
After hours of assembling,
the team is finally ready

497
00:33:20,899 --> 00:33:22,800
to raise the lift

498
00:33:28,006 --> 00:33:33,343
The crane hauls the machine to a
standing position, and then

499
00:33:34,045 --> 00:33:35,445
stops

500
00:33:38,650 --> 00:33:39,811
There's a problem

501
00:33:40,519 --> 00:33:43,648
The crane has a built-in scale,

502
00:33:43,722 --> 00:33:48,922
and Cirillo discovers
the lift is too heavy

503
00:33:51,730 --> 00:33:53,810
The load is 600 kilos overweight

504
00:33:54,099 --> 00:33:57,228
Over this distance
that's a problem

505
00:33:59,237 --> 00:34:01,729
The crane has the power
to raise the lift,

506
00:34:02,440 --> 00:34:05,672
but when its arm extends
out over the Colosseum,

507
00:34:05,744 --> 00:34:09,840
too much weight could cause
the crane to tip over

508
00:34:09,915 --> 00:34:13,147
We don't know if we can get
the lift inside

509
00:34:13,218 --> 00:34:16,746
The main issue is the crane
might topple over

510
00:34:16,821 --> 00:34:20,690
The team does some quick math
to try to save the project

511
00:34:23,194 --> 00:34:25,390
According to our calculations,

512
00:34:26,097 --> 00:34:28,965
the cage weighs around 450 kilos

513
00:34:29,034 --> 00:34:31,594
Once we take that away, the load
will be lighter for the crane

514
00:34:31,670 --> 00:34:38,372
They remove the cage, but
they're still 150 kilos...

515
00:34:38,443 --> 00:34:40,139
Or about 300 pounds... over

516
00:34:43,682 --> 00:34:50,555
Umberto confers with Cirillo
and takes a calculated risk

517
00:34:51,256 --> 00:34:55,091
He green-lights the raising
of the lift

518
00:35:00,632 --> 00:35:03,500
The crane hauls the lift up,

519
00:35:04,202 --> 00:35:08,697
nearly 200 feet and over
the walls of the Colosseum

520
00:35:08,773 --> 00:35:14,371
Umberto holds his breath as
the crane's arm stretches out

521
00:35:14,446 --> 00:35:15,846
over the hypogeum

522
00:35:17,482 --> 00:35:20,646
This shifts the crane's center
of gravity

523
00:35:23,989 --> 00:35:28,757
If the lift is still too heavy,
the crane could topple over,

524
00:35:29,461 --> 00:35:31,259
crashing into the Colosseum

525
00:35:31,329 --> 00:35:33,662
and smashing the lift
into the hypogeum

526
00:35:41,840 --> 00:35:44,776
To make it even more
challenging,

527
00:35:45,477 --> 00:35:46,843
Cirillo has to maneuver the lift

528
00:35:46,911 --> 00:35:50,245
without even being able
to see it,

529
00:35:50,315 --> 00:35:51,943
guided only by radio contact

530
00:35:58,189 --> 00:36:01,125
Rosella Rea, director
of the Colosseum

531
00:36:01,826 --> 00:36:04,694
and perhaps the person with the
most riding on the success

532
00:36:04,763 --> 00:36:09,258
or failure of the lift project,
arrives at the critical moment,

533
00:36:09,334 --> 00:36:11,200
as the team steers the lift

534
00:36:11,269 --> 00:36:14,433
between the narrow, fragile
walls of the hypogeum

535
00:36:14,506 --> 00:36:16,839
with almost no wiggle room

536
00:36:23,915 --> 00:36:30,219
To everyone's immense relief,
the lift slides in perfectly

537
00:36:41,132 --> 00:36:44,034
After flying the three-ton lift
into place,

538
00:36:44,736 --> 00:36:47,706
the half-ton cage is a breeze

539
00:37:05,090 --> 00:37:08,686
Well, when you look at it as a
drawing, when you imagine it

540
00:37:09,394 --> 00:37:11,488
in your mind's eye, or when you
write about it,

541
00:37:11,563 --> 00:37:13,429
that's one thing

542
00:37:13,498 --> 00:37:16,434
But then to see it full scale,

543
00:37:16,501 --> 00:37:20,268
and to really be able to touch
it, that's a whole other thing

544
00:37:20,338 --> 00:37:25,470
It's really amazing, and for me
it's especially fantastic

545
00:37:28,680 --> 00:37:34,642
With the lift in place,
the team pops the Prosecco

546
00:37:35,353 --> 00:37:37,049
But they may be celebrating
too soon

547
00:37:37,756 --> 00:37:39,987
They still have to turn
all these parts

548
00:37:40,692 --> 00:37:42,490
into a working machine

549
00:37:49,501 --> 00:37:52,369
But why did the ancient Romans
go to such lengths

550
00:37:53,071 --> 00:37:57,202
to make death theatrical?

551
00:37:57,275 --> 00:38:01,110
Some answers are coming
from the victims themselves,

552
00:38:01,179 --> 00:38:04,115
or at least their bones

553
00:38:04,182 --> 00:38:10,088
In 1993, Austrian archaeologists
uncovered a cemetery

554
00:38:10,155 --> 00:38:14,217
in a Roman city
in what is today Turkey

555
00:38:14,292 --> 00:38:17,956
Fabian Kanz of the Medical
University of Vienna

556
00:38:18,029 --> 00:38:22,933
was brought in to analyze
the human remains

557
00:38:23,001 --> 00:38:24,993
It was a mass grave

558
00:38:25,069 --> 00:38:27,937
We found the remains
from 68 people

559
00:38:28,006 --> 00:38:32,637
And 66 have been young males,
aged between 20 and 30

560
00:38:32,710 --> 00:38:37,341
Unusual injuries offer a clue
to who was buried here

561
00:38:37,415 --> 00:38:41,079
The distance is about
five centimeters

562
00:38:41,186 --> 00:38:44,281
These holes in the head,
surely the cause of death,

563
00:38:44,322 --> 00:38:48,020
were almost certainly the result
of a trident...

564
00:38:48,092 --> 00:38:52,325
A weapon unique
to gladiator combat

565
00:38:52,397 --> 00:38:54,025
The Roman author Suetonius

566
00:38:54,098 --> 00:38:56,397
describes seven gladiator
characters,

567
00:38:56,467 --> 00:39:01,269
each with different costumes
and weapons

568
00:39:01,339 --> 00:39:04,503
One of the most famous pairings
is a Secutor,

569
00:39:04,576 --> 00:39:09,446
equipped with a short sword,
shield and helmet;

570
00:39:09,514 --> 00:39:11,847
and a Retiarius,
"the fisherman,"

571
00:39:11,916 --> 00:39:15,216
who fought with a net
and trident

572
00:39:15,286 --> 00:39:18,620
From the forensic evidence, it's
obvious who won this battle

573
00:39:21,159 --> 00:39:24,425
It was the first known
gladiator cemetery

574
00:39:25,129 --> 00:39:27,030
We had in our hands
for the first time

575
00:39:27,098 --> 00:39:29,624
remains of real gladiators

576
00:39:29,701 --> 00:39:34,264
Among many of the gladiator
bones, Kanz finds something

577
00:39:34,339 --> 00:39:40,040
even more remarkable...
Evidence of healing

578
00:39:40,111 --> 00:39:41,977
What was quite surprising for us

579
00:39:42,046 --> 00:39:45,016
was the high number
of well-healed injuries,

580
00:39:45,083 --> 00:39:48,884
which indicates there must be
excellent health care

581
00:39:48,953 --> 00:39:50,148
for these gladiators

582
00:39:52,257 --> 00:39:56,524
Ancient Roman texts offer a clue
to one possible treatment,

583
00:39:57,228 --> 00:40:00,721
a special potion made from ash

584
00:40:00,798 --> 00:40:05,930
And this might have been leaving
traces in the bones

585
00:40:06,004 --> 00:40:08,644
To find out if there's any truth
to this gladiator potion,

586
00:40:08,706 --> 00:40:12,700
Kanz grinds a bone sample
into a powder

587
00:40:12,777 --> 00:40:15,713
and processes it into a liquid

588
00:40:15,780 --> 00:40:20,218
that he puts into an instrument
called an emission spectrometer

589
00:40:20,285 --> 00:40:24,188
Here he sprays the liquid
into an argon gas torch,

590
00:40:24,255 --> 00:40:28,886
where it burns with
a distinctive flame

591
00:40:28,960 --> 00:40:30,451
The color of the flame changes,

592
00:40:30,528 --> 00:40:32,656
depending on the elements
in the liquid

593
00:40:32,730 --> 00:40:35,962
And therefore, we can find out
about the mineral composition

594
00:40:36,034 --> 00:40:37,525
of the bone

595
00:40:37,602 --> 00:40:42,131
The flame turns from blue
to a bright yellow,

596
00:40:42,240 --> 00:40:45,540
indicating that the gladiator
bone has a high concentration

597
00:40:45,576 --> 00:40:48,045
of strontium

598
00:40:48,112 --> 00:40:49,774
Strontium is a natural element

599
00:40:49,847 --> 00:40:52,442
with properties similar
to calcium,

600
00:40:52,517 --> 00:40:55,681
a crucial mineral for building
strong bones

601
00:40:55,753 --> 00:40:57,915
It was mentioned
in the historic texts

602
00:40:57,989 --> 00:41:03,929
that a kind of ash drink was
substituted to the gladiators

603
00:41:03,995 --> 00:41:06,055
to remedy their pain
after fighting

604
00:41:06,130 --> 00:41:08,497
And this would perfectly fit

605
00:41:08,566 --> 00:41:12,503
to explain this high strontium
content of the gladiators

606
00:41:18,142 --> 00:41:21,010
Kanz believes gladiators were
given the Roman equivalent

607
00:41:21,713 --> 00:41:26,981
of calcium supplements
to strengthen their bones

608
00:41:27,051 --> 00:41:30,579
But why go to this trouble
to save gladiators?

609
00:41:30,655 --> 00:41:34,615
Although slaves,
gladiators were trained

610
00:41:34,692 --> 00:41:36,388
in special fight schools

611
00:41:36,461 --> 00:41:40,262
The remains of one,
the Ludis Magnus,

612
00:41:40,365 --> 00:41:43,563
are right in the shadow
of the Colosseum

613
00:41:43,601 --> 00:41:46,036
The gladiators have been
a big investment

614
00:41:46,104 --> 00:41:48,505
for the owner
of the gladiator school,

615
00:41:48,573 --> 00:41:52,510
comparable to modern football
or soccer teams

616
00:41:52,577 --> 00:41:55,137
And they wanted to save
their investment

617
00:41:55,213 --> 00:41:58,206
And therefore, they engaged
the best available doctors

618
00:41:58,282 --> 00:42:00,114
at the time

619
00:42:00,184 --> 00:42:04,588
It would have been
extremely expensive

620
00:42:04,655 --> 00:42:08,592
if half the gladiators were
killed at every event

621
00:42:08,659 --> 00:42:10,890
To protect their investment,

622
00:42:10,962 --> 00:42:14,990
the Romans began to provide
gladiators with medical care,

623
00:42:15,066 --> 00:42:18,161
so they could live to fight
another battle

624
00:42:18,236 --> 00:42:21,331
And perhaps to compensate
the audience for a reduction

625
00:42:21,406 --> 00:42:23,238
in the number of deaths,

626
00:42:23,307 --> 00:42:25,333
the emperor added
entertainment value

627
00:42:25,410 --> 00:42:30,110
by ordering
more elaborate stagecraft

628
00:42:36,954 --> 00:42:40,550
Now, all the major parts
of the lift are in place:

629
00:42:41,259 --> 00:42:46,220
the cage, capstan and trap door

630
00:42:48,132 --> 00:42:50,932
Now that it's in place,
we have to make it work

631
00:42:51,402 --> 00:42:54,895
The first task is installing
all the missing pieces

632
00:42:56,174 --> 00:43:01,374
They place wheels on the cage

633
00:43:02,080 --> 00:43:05,778
handles on the capstan

634
00:43:05,850 --> 00:43:09,685
and above the capstan,
Umberto and Tullio install

635
00:43:09,754 --> 00:43:10,778
a spool for rope

636
00:43:12,190 --> 00:43:14,989
We attach this rope here
and as it turns,

637
00:43:15,693 --> 00:43:17,559
the rope wraps around it
and pulls the cage up

638
00:43:21,699 --> 00:43:26,262
The team connects the capstan
to the cage with enough rope

639
00:43:26,971 --> 00:43:30,533
to stretch the length of two
football fields

640
00:43:30,608 --> 00:43:35,239
Their earlier model is starting
to feel very small indeed

641
00:43:36,047 --> 00:43:38,710
We only tested the model

642
00:43:39,417 --> 00:43:42,046
That was just 50 kilograms

643
00:43:42,120 --> 00:43:48,549
The real thing is 3,200
kilograms

644
00:43:48,626 --> 00:43:50,959
So that's why things
are a bit tense here

645
00:43:54,432 --> 00:43:55,957
With everything strung up,

646
00:43:56,667 --> 00:44:01,503
Umberto gives the lift
a trial run

647
00:44:01,572 --> 00:44:04,736
He tries to turn the capstan
without success

648
00:44:04,809 --> 00:44:07,802
The cage goes nowhere

649
00:44:09,347 --> 00:44:14,217
Three of us tried to lift it,
but it didn't budge

650
00:44:14,919 --> 00:44:16,251
Not a bit

651
00:44:16,320 --> 00:44:18,448
It looked like an elephant

652
00:44:18,523 --> 00:44:20,116
Impossible to move

653
00:44:21,759 --> 00:44:26,754
Umberto calls in reinforcements

654
00:44:27,465 --> 00:44:29,934
Even with six people,
they can't turn the capstan

655
00:44:30,001 --> 00:44:34,803
to lift the cage
or move the trap door

656
00:44:34,872 --> 00:44:36,704
It's all too heavy

657
00:44:41,212 --> 00:44:42,612
The ramp is very heavy

658
00:44:43,247 --> 00:44:45,011
and the lever system we
initially designed

659
00:44:45,082 --> 00:44:46,082
does not work

660
00:44:47,151 --> 00:44:50,679
How did the ancient Romans
manage to lift so much weight?

661
00:44:53,691 --> 00:44:56,525
We are facing the same
challenges that the Romans had

662
00:44:57,228 --> 00:45:00,255
when they were originally
making it

663
00:45:00,331 --> 00:45:03,324
The size is the same, the
mechanisms are the same,

664
00:45:03,401 --> 00:45:06,599
and the problem is just as big

665
00:45:08,940 --> 00:45:14,572
Umberto searches for a solution
in an unexpected place:

666
00:45:15,279 --> 00:45:18,113
Roman ships

667
00:45:18,182 --> 00:45:21,744
Could the same mechanics that
hoisted the heavy sails

668
00:45:21,819 --> 00:45:24,118
be used to lift the cage?

669
00:45:25,957 --> 00:45:29,018
Umberto's hard drives are filled
with images he's collected

670
00:45:29,727 --> 00:45:33,027
of surviving pieces
of Roman ships

671
00:45:33,097 --> 00:45:36,864
Among them he finds what may be
the key to heavy lifting,

672
00:45:36,934 --> 00:45:42,339
a simple device that dates far
back in antiquity... the pulley

673
00:45:42,440 --> 00:45:45,672
The cage weighs 800 pounds

674
00:45:45,710 --> 00:45:48,407
Adding a pulley splits
the weight evenly

675
00:45:48,479 --> 00:45:51,415
between the two sides
of the rope

676
00:45:51,482 --> 00:45:54,646
Another pulley changes
the direction of the force

677
00:45:54,719 --> 00:45:57,951
It's easier to pull down than up

678
00:45:58,022 --> 00:46:03,188
With one pulley attached to the
cage, it feels half the weight,

679
00:46:03,261 --> 00:46:07,289
only 400 pounds

680
00:46:07,365 --> 00:46:09,960
Attaching two pulleys
on the cage makes it feel

681
00:46:10,034 --> 00:46:13,368
like only 200 pounds

682
00:46:13,437 --> 00:46:15,201
The more pulleys you add,

683
00:46:15,273 --> 00:46:18,368
the more the weight is
distributed between them

684
00:46:18,442 --> 00:46:21,810
and the less force you need
to lift the cage

685
00:46:24,682 --> 00:46:26,922
The more I worked on this,
the more I realized

686
00:46:27,285 --> 00:46:31,154
how great the Romans were, and
how small we are in comparison

687
00:46:31,222 --> 00:46:36,092
Building the lift, I realized
I was learning from them

688
00:46:36,160 --> 00:46:38,789
Learning directly
from the ancient Romans

689
00:46:43,167 --> 00:46:46,194
The team adds pulleys
to redistribute the weight

690
00:46:46,904 --> 00:46:50,204
of the cage and trap door

691
00:46:55,279 --> 00:46:57,748
Umberto gathers eight men

692
00:47:03,020 --> 00:47:05,649
As they push the capstan,

693
00:47:06,357 --> 00:47:10,294
the rope glides through
a network of 12 pulleys

694
00:47:10,361 --> 00:47:16,198
And the cage lifts up
off the ground

695
00:47:19,303 --> 00:47:22,273
The fascinating part is seeing
this mechanism,

696
00:47:22,973 --> 00:47:25,568
which at first was essentially
a static,

697
00:47:25,643 --> 00:47:26,723
seemingly simple structure,

698
00:47:26,777 --> 00:47:30,407
turn into something dynamic,
a machine,

699
00:47:30,481 --> 00:47:35,385
simply by using these ropes,
pulleys and human strength

700
00:47:35,453 --> 00:47:37,945
But can this machine perform

701
00:47:38,022 --> 00:47:41,356
the Colosseum's signature
magic trick?

702
00:47:41,459 --> 00:47:46,591
To find out, the team wants
to release an animal

703
00:47:46,630 --> 00:47:49,566
into the world's most famous
amphitheater

704
00:47:49,633 --> 00:47:54,298
for the first time
in 1,500 years

705
00:47:54,372 --> 00:47:55,863
But which animal?

706
00:47:55,940 --> 00:48:01,174
According to legend, Romulus and
Remus, the founders of Rome,

707
00:48:01,245 --> 00:48:04,943
were suckled by a wolf

708
00:48:05,015 --> 00:48:09,885
So a wolf is the perfect animal
to test the lift

709
00:48:15,359 --> 00:48:18,295
Paolo Caldora rescues wolves
taken as pets

710
00:48:18,996 --> 00:48:23,195
and then illegally abandoned

711
00:48:23,267 --> 00:48:26,863
He leads a wolf through
the labyrinth of the hypogeum

712
00:48:28,372 --> 00:48:30,170
In ancient times,

713
00:48:30,875 --> 00:48:35,074
wild beasts would have been
carried in already in cages

714
00:48:35,146 --> 00:48:40,346
The cage door is lowered,

715
00:48:40,451 --> 00:48:44,582
and the men turn the capstan
to raise the wolf

716
00:48:49,660 --> 00:48:54,598
Every part is now working
as a synchronized machine

717
00:48:57,668 --> 00:49:03,130
The trap door is lowered

718
00:49:13,484 --> 00:49:21,484
The cage rises into place,
its door opens,

719
00:49:22,860 --> 00:49:26,763
and the wolf emerges
into the arena

720
00:49:38,843 --> 00:49:41,142
The days of wild beasts
in the Colosseum

721
00:49:41,846 --> 00:49:45,977
as hunters or hunted
are thankfully long gone,

722
00:49:46,050 --> 00:49:48,417
and the wolf runs safely
to his rescuer

723
00:49:56,827 --> 00:50:00,821
Heinz, Umberto and their team
have not only re-created

724
00:50:01,532 --> 00:50:03,728
an ancient Roman lift machine,

725
00:50:03,801 --> 00:50:06,396
they have created a time machine

726
00:50:06,470 --> 00:50:10,134
For a brief moment, raising
the wolf opens a window

727
00:50:10,207 --> 00:50:14,668
onto the spectacles here in
the Colosseum 2,000 years ago

728
00:50:17,414 --> 00:50:19,414
Imagine not just one lift here,

729
00:50:19,617 --> 00:50:23,987
but a whole row of them,
one behind the other

730
00:50:24,054 --> 00:50:25,613
The corridor was packed
with lifts,

731
00:50:25,689 --> 00:50:28,784
which produced the spectacular
action above

732
00:50:28,859 --> 00:50:32,318
Now, with the full-scale lift
we can begin to get a sense

733
00:50:32,396 --> 00:50:35,127
of just how magnificent the
stagecraft must have been

734
00:50:35,199 --> 00:50:37,031
It's really fantastic

735
00:50:43,607 --> 00:50:49,604
Each year, over five million
tourists visit the Colosseum

736
00:50:50,314 --> 00:50:52,010
They are awed by its size

737
00:50:52,082 --> 00:50:55,610
and horrified
imagining the slaughter

738
00:50:57,087 --> 00:51:00,421
How could a culture
as advanced as Rome

739
00:51:01,125 --> 00:51:05,028
justify the spectacular
bloodshed that took place here?

740
00:51:05,095 --> 00:51:08,657
Gladiatorial games and
associated violent spectacles

741
00:51:08,732 --> 00:51:13,170
needed absolutely
no justification

742
00:51:13,237 --> 00:51:15,763
And in the ancient sources,
we find just the opposite,

743
00:51:15,839 --> 00:51:20,607
that they were believed
to stiffen moral fiber

744
00:51:23,113 --> 00:51:27,346
Romans attending the Colosseum
were more than spectators,

745
00:51:28,052 --> 00:51:29,953
they were participants

746
00:51:30,020 --> 00:51:35,425
These games showcased the power
of Rome and reminded citizens

747
00:51:35,492 --> 00:51:40,157
that their prosperity
was paid for in blood

748
00:51:40,264 --> 00:51:43,393
Inside the Colosseum you have
spectacle, you have energy,

749
00:51:43,434 --> 00:51:45,596
you have entertainment

750
00:51:45,669 --> 00:51:48,798
The whole building is used as
a vehicle for the demonstration

751
00:51:48,872 --> 00:51:50,500
of the power of the Roman world

752
00:51:50,574 --> 00:51:52,668
and how it came to benefit
the populace

753
00:51:55,045 --> 00:51:58,743
Though Rome falls
to the barbarians in 476,

754
00:51:59,450 --> 00:52:05,822
the Colosseum, like a victorious
gladiator, still stands

755
00:52:05,889 --> 00:52:08,415
Battered and triumphant,

756
00:52:08,492 --> 00:52:14,295
it is a lasting reminder of
the gore and the glory of Rome
