It may have been the spark that launched the scientific age:

a machine to make books.

Never before had it been possible to spread knowledge

so fast and to so many people.

That's really an information revolution.

But first came the page.

And this is the first paper in the world.

Made from plants.

Made from animals.

I am the only traditional master parchment maker

left in the world, which is quite unique.

Medieval books were not made by vegetarians.

And the final ingredient,

a bit of luck,

hidden in the shape of a letter.

This is a modular way of writing, and in fact,

if I want to make little blocks of metal with them, no problem,

because I'm already there, basically.

The design has already happened.

This text here is legible Arabic.

It shows a remarkable advance in Arabic printing technology.

"A to Z: How Writing Changed the World,"

right now, on "NOVA."

In the year 1448 in Mainz, Germany,

a goldsmith named Johannes Gutenberg

was experimenting with a lead alloy and a hand-held mold.

His aim was to speed up the process of putting ink on paper.

But what he did was speed up history.

Gutenberg's invention spelled the end of the Middle Ages

and ushered in the modern world of science and industry.

Every innovation of today

is built on this foundation.

Yet, behind Gutenberg's press lay centuries of development

and change in the way words were written,

without which he could never have succeeded.

This is the story of history's most important technology,

the technology of putting words on a page.

I'm making a pen out of a drinks can,

and it's one of my favorite pens

because it can do so many different things,

and also because it means,

no matter where in the world I am, I always have a pen.

There's trash everywhere...

Brody Neuenschwander is a calligrapher and modern artist

who has studied the writing practices of different cultures

throughout history.

Now, a pen is a simple tool in any case.

All it is is a... point with a reservoir,

and the reservoir holds the ink and brings it to the point,

and you write with it.

I'm going to use my drinks-can pen to write a short phrase

from a poem by Hopkins, "As Kingfishers Catch Fire."

The first stroke is going to make quite a noise,

so watch out... the A...

And flow into an S made with a nice movement of the arm.

I can also make a very

fat and juicy stroke for the K.

This is calligraphy as art,

where legibility takes second place to expression

and the letters can be hard to make out.

But for most of history,

making out the letters has been essential.

Writing is one of the most fundamental things

that human beings do,

one of the great motors of civilization,

and to understand how people wrote in previous societies

helps us to understand

many of the other aspects of the society.

But is it possible to know how people wrote

thousands of years ago?

Brody believes that calligraphy can help.

The one thing that's amazing about calligraphy is,

we can go right back

to the materials and tools of earlier times

and reproduce nearly exactly the conditions of writing.

So, it's a sort of experimental approach to historical research

using the real tools and materials

that were used in earlier times.

Running a nation has always required

some form of written communication.

And the world's first nation-state was Ancient Egypt,

a state which employed one of the earliest writing systems.

Egyptian hieroglyphs can still be read

in monumental inscriptions carved in stone.

But the Egyptians also had

a portable, everyday medium on which to write.

Brody has come to Egypt

to learn about this pioneering information technology.

My name is Sam.

I'm Brody.

Welcome, I'll give you a brief idea

about this plant, the papyrus plant,

and how the Ancient Egyptians

were using this plant to make a paper.

Papyrus is a type of sedge

which grows all along the banks of the Nile.

Readily available and easily harvested,

this unassuming plant was turned by the Egyptians

into one of the foundations of civilization.

We remove the green parts.

All of the green cover.

We divide it into long and thin slices like this.

But that part once was breakable, as you can see.

Or easy to break.

To make the slices

more flexible, we use this.

The slices now will be more strong and more flexible

than that part, it was break.

Then we soft the slices in fresh water.

After two weeks, we take the slices from the water.

We arrange them between

two pieces of cotton.

This is the slices that we have here, the slices.

In vertical and horizontal lines like this.

One vertical, another horizontal, without any space.

One by one and two by two till we complete the whole sheet.

We cover them.

We put them under a press machine for one week.

One week under the press,

we get this paper.

And this is the first paper in the world.

Well, it feels like a wonderful surface.

I think I would really enjoy writing on it, actually.

As civilization spread from Egypt across the Mediterranean,

so did papyrus.

It became an important export,

and when Egypt was finally conquered,

by the Roman Empire in 30 BC,

one of the biggest prizes of conquest

was domination of the Mediterranean papyrus trade.

The Romans had a large and complex empire

that ran on the written word,

and papyrus, being their form of paper, was imported from Egypt

and it's shipped over here in enormous quantities.

And papyrus rolled up into scrolls

was for centuries the Roman book.

If there was a fresco of a householder

wanting to show they were literate,

they would be holding a scroll.

Very deeply ingrained.

Literacy was surprisingly widespread in Rome.

It even extended to the large enslaved population in the city,

which provided most of the scribes

who wrote those high-status scrolls.

But what was the technology they used

to put ink to papyrus?

Romans used a reed pen to write with on papyrus.

It's cut to a very fine point.

It's a fairly soft material,

and the pithy side will absorb ink quite a bit,

so instead of having a natural reservoir like a quill has,

it's actually the wood itself

absorbing a certain charge of ink.

Brody sets out to copy a letter sent from Rome to Egypt,

preserved in the desert sand for nearly 2,000 years.

It's written in a very simple, casual daily script.

So, I'm going to see what it's like to...

write those letters with this, this reed pen.

You always learn a lot at the very first moment

that you touch the pen to the, to the writing surface.

And what I'm seeing is that

the horizontal fibers of the papyrus are guiding my pen.

And you wouldn't really need to draw lines

because they're already there.

That saves you a lot of time.

And it's slippery... that's, that is very noticeable,

just how slippery this surface is,

so it's almost like skating, and I find it...

I'm naturally encouraged

to write a very quick hand here.

The reed is very light in my hands

and there's no resistance from the, from the papyrus at all,

so I think you could have a nice, long working day

as a Roman scribe... as long as the light held,

you'd be able to keep churning out your Ovids for your master.

Yes, it's amazingly fast, really.

It's a, it's a surface made for speed.

So, copies could be churned out relatively quickly

by the inexpensive labor of the enslaved.

The materials were cheap, too.

That meant that a Roman bookshop

would have something for almost every pocket.

Spaces like this are fairly typical for Roman shops,

a single room opening straight onto the street.

And here's this lovely Travertine lintel,

and you can see in it, there's a groove here

for wooden shutters that might close it off at night

to keep the stock secure.

For the ordinary man and woman in the street,

booksellers were a great place to get hold of literature

at a not exorbitant price.

So ranging from a few coins for the cheapest book,

that's a soldier's daily wage.

And if you couldn't afford a particular book,

you could always go and consult it

in one of Rome's public libraries.

As well as the commercial booksellers,

there were public libraries founded by the emperors.

We know of about 29 of them by the late antique period.

So, lots and lots of them.

It all adds up to a picture of a world

where books were widely available.

In the libraries, we can estimate

maybe tens of thousands of scrolls.

And that's just the big public collections.

So around us here in this square mile or so of the city center,

maybe hundreds of thousands of scroll books.

But that thriving literary culture was all based

on the ready availability of papyrus.

And by the end of the third century,

Rome's control over the Mediterranean had begun to slip.

Over time, the Roman Empire split into East and West,

seaborne trade became harder and more expensive to do

as the empire fragmented,

and the trade in papyrus became harder and harder to sustain.

And you can count the number of fragments of books

that survive by each century,

and you can see the number goes down and down.

So there were just fewer books being made.

And this city of great libraries

and thousands of thousands of papyri changes,

and a late antique writer says, "Libraries are shut up now

and echoing like tombs and empty."

Rome's empire shrinks

and becomes the start of the new Christian Middle Ages.

The fall of the Roman Empire

coincides with a change in the technology of writing in Europe.

As papyrus disappeared,

so did the book as a relatively inexpensive, everyday commodity.

Books would become rare and precious objects,

as Europeans turned to a new

and much more expensive material on which to write.

I'm Lee Mapley.

I am the only traditional master parchment maker

left in the world, uh, which is quite unique.

Essentially, we're taking a raw material,

completely natural sheepskin, calfskin, or goatskin,

and we are converting it into a beautiful writing material.

I'll tie the skin into a frame and it has to be stretched.

I'm re-aligning the fibers of the skin

to get it nice and solid, to keep that nice flat surface.

So then, I can also work any flesh off the skin

and work the grease out of the skin in the frame.

So, it's literally elbow grease and hot water

to remove that grease from the skin.

For a thousand years,

this was the only writing surface Europe had.

It's a piece of parchment.

Now, medieval books were not made by vegetarians.

And you can see that it's an animal product

because running right down the center, this pale zone,

is the spine of the animal,

with the pelvic bones even shown here.

Here we would fold to make a large book,

and that's why we call it the spine of a book.

The fact that parchment could be folded made it possible

to stitch leaves together into a codex,

the form of the modern book.

Each sheet of parchment would yield

eight pages of an octavo volume,

which meant that it took a lot of animals

to make a single book.

The medieval pen was also an animal product:

a bird's feather.

Cutting a quill starts with shortening it.

Sadly, it's a little less romantic that way,

but otherwise, it would stick in your eye.

And then you have to open the end of it and make a slit,

and the slit that I make now by lifting the knife

is what brings the ink to the point of the pen,

and then, starting on the other side, I cut

from one side towards the slit that I just made, and then,

towards the, from the other side towards the slit,

and I make a symmetrical point.

Now, I use a lot of different tools, modern ones and all,

but I've still never found anything better

than a good swan quill.

I'm working on a really wonderful

piece of parchment here.

It's got just the right surface to give me sharp letters

and a lot of control.

Parchment is not a material that

you would ever try to write quickly on.

It holds the pen as you write, so you don't skate or slip,

and it really encourages a sort of majestic, graceful,

slow, and careful way of writing.

When you write on parchment,

the ink as it dries

is grabbed by the fibers, which close down and hold it.

It's almost like you're tattooing the surface.

At the pace I'm writing now, I could probably write,

in a really good day, two pages of one of these great Bibles.

Certainly not more.

And eight hours a day, that's not really possible.

It's, it's too focused, it's too concentrated,

and in the end, it's too tiring, so, I think that

a six-hour day yielding two full pages

would be a very, very good day.

Where were all these labor-intensive,

costly books being produced?

As it happens, Brody's studio is in Bruges.

In the Middle Ages, this city was a great center

of book production, responsible at times

for as much as ten percent of all the books

being made in Western Europe.

At the city archives, Brody visits Ludo Vandamme

to try to put what he's learned about writing

on parchment into historical context.

What we see here

are all the members working in book industry

in Bruges at that moment. Oh!

But that's unique.

How many members are we talking about here?

About 50, 60 at that moment. Okay.

Men and women. Yes.

Each workshop might have employed a handful of scribes,

but Brody's experiment shows that it would have taken months

for a scribe to copy a whole book.

So, if I think we have... 50 workshops,

each making several books a year, that means that

the number of books being finished

is in the hundreds in Bruges, not in the thousands.

Is that a fair guess?

Can agree, yes. And all of Northern Europe, then,

a few thousand, no more. Mmm.

So, there's very little access to information

at this time in Europe.

Medieval books were rare and precious.

I have something I want to show you.

What is this?

This is a contract to make a book,

a luxury book in two volumes,

for a patron, a commissioner,

and he says it will cost 20 pounds, this luxury book.

And he also says

how long it takes him to finish the book.

Almost a year.

Any way of guessing what 20 pounds is worth?

20 pounds at that moment,

um, let's say a modest house in Bruges.

A middle-class house. Oh, my goodness!

It's an astonishingly expensive information technology.

Yeah.

The libraries of Bruges still have examples

of the sort of book that cost as much as a house.

This is the absolute luxury manuscript.

You couldn't get anything more precious,

more expensive, and more prestigious than this.

I'm looking at gold which would have had to have been beaten

into thin sheets to be applied to the page.

I'm looking at blue

which actually came all the way from Afghanistan.

I'm looking at malachite green brought from Central Europe.

It is an 800-page book,

which represents 400 animals.

400 animals!

In a very agrarian economy.

Books like this represent a pinnacle of medieval art,

but they also represent a limitation

on literacy and scholarship

compared to the broad literary culture

of the ancient world.

When I started my experiments with a reed pen

on papyrus, I was astonished with how quick it was.

Now, first of all, papyrus was a cheap writing material.

That means that books were accessible

to a certain segment of the population

in Greek and Roman times.

I think we could almost say that the Middle Ages is that period

when papyrus is no longer used, no longer available,

and parchment becomes the writing surface.

What do we gain from it?

This world of beautiful illuminated manuscripts.

What do we lose?

A broader reading culture.

So the shift from antiquity to the Middle Ages

is the shift from papyrus to parchment,

and the shift from a wide literate public

to a very small one.

Very interesting to see how writing materials and techniques

can have such an immense influence

on cultural development.

But what about other cultures, further to the East, in Asia?

In China, a rich literary and artistic tradition developed,

based on a distinctive pictorial script

and a unique writing technology.

The key components of that technology

are traditionally known as

"the four treasures of the study."

First is paper.

Then, the brush.

And the calligrapher needs an ink stone

on which to grind her ink,

which comes in the form of a stick of solid pigment.

The four treasures

allow Wang Jianing to practice brush calligraphy

in much the same way as it has

been for thousands of years.

Brush calligraphy produced works of art that were prized in China

every bit as much as illuminated manuscripts were in Europe.

But in a medieval manuscript,

the art is in the decoration around the text.

The nature of the Latin alphabet

and the characteristics of parchment

produced letters that were regular and repetitive.

But in Chinese brush calligraphy,

the art is in the brushwork

that produces the characters themselves.

And that is made possible by the nature of the writing surface.

Paper was invented in China in the second century,

and by the seventh century,

paper making was an important Chinese industry.

Paper was key to another Chinese invention:

woodblock printing.

Each page of text

was glued on to a wooden block,

and then the characters were carved out

by a skilled craftsman.

This step was laborious and expensive.

But once the wood block was produced,

it was quick and cheap to print from,

thanks to paper that was absorbent,

flexible, and inexpensive.

And because Chinese paper didn't tear easily,

it was a simple matter to stitch the pages together into a book.

Indeed, paper was so plentiful

that even a thousand years ago,

Chinese people could buy blank notebooks.

Such an aid to thought

would have been inconceivable in medieval Europe,

where every single blank page

was an expensive and scarce resource.

In a world of parchment,

many thoughts must have gone unrecorded.

A source of pride, but also a state secret.

For 600 years, only the Chinese knew how to make paper,

but nothing can be kept hidden forever.

This is the Meros Paper Mill near Samarkand,

a key city on the Silk Road

between China and the Mediterranean.

In the Middle Ages,

there were hundreds of such water-powered paper mills

operating in the region,

churning out paper for the Islamic empire

of the Abbasid caliphs.

Paper making had come to Samarkand

as the result of a battle.

In 751, the westward expansion of the Tang Dynasty

was checked by Arab forces at the River Talas.

It was a defeat that ensured that to this day,

the principal religion of Central Asia would be Islam.

And in the captured baggage train

of the Chinese army were paper makers.

The secret was out:

how to turn the bark of the mulberry tree

into the seemingly humble material that was the foundation

of Chinese culture and power.

To make mulberry bark paper, you take the new growth of the tree,

these sticks here, and you

peel off the outer bark, which is very thin,

you can peel it in one pull like that.

You have a golden inside and a rough woody outside.

You can then, as you see here,

Rukhsona, with her great Samarkandi swordsmanship,

can with a quick flick of the knife

peel away the brown outer skin,

and then that leaves you with

this pure inner pith,

which is the fibers of the mulberry tree,

and they'll need to be cooked and softened

in the next stage of the process.

After cooking,

the mill pounds the mulberry pith

for up to eight hours

to produce a pulp.

Added to water,

the pulp makes a thick soup of cellulose fibers,

which are scooped up in a rectangular sieve.

As the water flows through the sieve,

it leaves behind a thin mat of the fibers.

This is pressed between pieces of cotton

to form a single sheet of paper...

Which can later be hung up to dry.

Then, the Islamic papermakers

added a new step to the Chinese process.

They polished each sheet

to produce a smooth writing surface.

The preparation of paper for Islamic calligraphy

is quite a process.

And the reason is, is that they use a reed pen,

as the Ancient Romans did, but it's cut to a wide point.

And that wide point is going to be pushed

from right to left

to make the long strokes of Arabic calligraphy.

And therefore you cannot have any unevennesses

or any roughnesses in the paper.

The first thing I notice is

that the strokes need to be made pretty slowly,

because if I'm going fast, the ink is pulling back.

It's a matter of finding the right speed and pressure.

That's really fascinating.

At the beginning, I was going too fast

and the ink was pulling back,

but I've found the speed that this paper is demanding,

and now my ink is staying just where I put it.

What we have here with Islamic paper is something that's cheap

but very sophisticated,

very finely manicured, and tailored

to making extremely graceful calligraphy.

In Samarkand during the Middle Ages,

the paper making industry was on a surprisingly impressive scale.

There were perhaps as many as 400 paper mills

operating in this region in the Middle Ages,

all the way to the 18th century,

supplying paper to the entire Islamic world.

The production of a factory like this

would have been several thousand sheets a day,

and if you take that times 400,

we have millions of sheets of paper being made every day.

This was the paper that

supplied the entire Islamic world

with the basis for its intellectual, religious,

and cultural life.

And that intellectual life was rich indeed.

The five centuries that followed the beginning of paper making

in Samarkand came to be known as the Islamic Golden Age.

The arts and sciences flourished.

Islamic scholars made discoveries in geology, biology,

medicine, and especially mathematics.

They gave us the words algebra and algorithm,

and we still count using Arabic numerals.

Samarkand was itself a great center of scholarship.

In Registan Square,

three great Islamic universities face each other.

They are covered in monumental Arabic calligraphy...

Praising God and extolling the virtues of learning.

The oldest of the three universities

was founded by Ulugh Beg,

ruler of Samarkand in the 15th century.

But today, Ulugh Beg is famous not as a prince,

but as an astronomer.

Nearby the university, Ulugh Beg built an observatory.

It's long gone, except for the part that was underground.

The top half of the sextant once reached 100 feet above ground,

making it by far the largest such instrument ever built.

Sunlight would have illuminated the curved track,

which is marked very precisely with degrees.

A copper ruler inserted in one of these slots

measured the fraction of a degree,

called the minutes of arc.

Ulugh Beg used the sextant to measure

the height of the sun at noon each day.

At midsummer and midwinter,

this allowed him to determine the length of the solar year.

The scientific observations being made here

were far in advance of anything happening in Europe at the time.

Islamic science,

and the paper it was written on,

would eventually find its way to Europe...

Where it would help to lay the foundations

of a scientific revolution.

This star catalogue, published in Poland in 1690,

lists the position of the fixed stars

as determined by six great astronomers.

Ulugh Beg is among them.

This extraordinary frontispiece

shows the Ancient Greek Ptolemy, Tycho Brahe...

Ulugh Beg is the one with the

long mustache in the image,

sitting at table being highly honored in this sequence

of persons who'd had mighty observatories

and made observations of the fixed stars.

So you've got a succession

on each side of astronomers,

and the idea in this image is that

the catalogs are steadily improved as each

passes on their findings for improvement

by their successors.

By the time this star catalogue was published,

the ancient view of the heavens had been radically transformed

by the discoveries of astronomers like Galileo,

Copernicus, Kepler, and Isaac Newton.

They were all Europeans,

proof that by the 17th century,

European intellectual life no longer lagged behind

the scholarship of the Islamic world.

And that change had been made possible by a revolution

in the production of the written word,

for this is a printed book.

The impact of printing in the Western world

is comparable in scope in all areas of learning

to the impact in the Islamic world of the use of paper.

Printing would eventually spread the written word

to every level of European society.

But how did this radical new technology

find a market in a world

where books were a luxury for the very rich?

The European printing revolution began

in the German town of Mainz

in 1448,

when Johannes Gutenberg,

a goldsmith by trade,

began casting the letters of the Latin alphabet in metal.

Gutenberg was looking for a way to produce multiple copies

of the same text in a much faster way than

scribes could copy texts in the manuscript period.

Gutenberg's idea as to speed up the process

of putting words on a page by replacing the scribe

with a machine.

The secret of Gutenberg's printing press

was his ability to mass-produce multiple copies in metal

of each individual letter.

And in this, he had a hidden advantage:

the nature of the Latin alphabet.

The letters of the Latin alphabet

are really very simple shapes,

and when you write them in the way they would have been written

at the time printing was invented,

all the letters are very clearly separate.

This is a modular way of writing, and, in fact,

if I want to make little blocks of metal with them,

no problem, because I'm already, I'm already there, basically.

The design has already happened.

These simple block-like letters can become blocks of metal

and can be printed.

But it's easy for us to forget

what a big risk Gutenberg was taking.

To set up his print shop took capital,

capital which would have to be repaid.

And so it was vital

that the first book he printed turn a profit.

Well, this is one of the really great treasures

of Lambeth Palace Library.

It's a copy of the Vulgate Bible

printed by Johannes Gutenberg in Mainz in the mid-1450s.

So it's a copy of the first substantial printed book

to be produced in the West with movable type.

The people who bought books in the 15th century

were a small and elite group

of rich individuals and institutions.

Every book they had ever seen was a manuscript,

and they had a clear idea of what a book should look like.

What people would have really prized in the manuscript book,

and would have thought marked it out as a manuscript

of high quality, was the regularity of the text

and of the letter forms,

the evenness of the inking,

the contrast between the white of the page

and the black of the text...

Those qualities... regularity of letter forms

and of line length... were precisely the characteristics

of movable type.

What was a challenge for the scribe

was straightforward for the typesetter.

So, movable type could produce a printed book

that matched the quality of the manuscripts

that readers were used to looking at and buying.

And Gutenberg didn't stop there.

He printed on parchment

and had the printed text illuminated by hand.

The impression of a manuscript is so complete

that for hundreds of years,

the librarians at Lambeth Palace were fooled.

And until the early 19th century,

it was thought to be a manuscript.

It was catalogued as a manuscript.

And I think Gutenberg would have been delighted by our confusion,

because what he was trying to, to achieve

with the printing of this book

was to produce a book by a new technique

that people would, would think was just as good

as the manuscripts that they were used to buying

and reading.

So what he was trying to do

was to do, to do something new that would seem old.

Gutenberg's strategy worked.

His printed Bible sold with ease.

He soon had imitators,

and within a few decades,

there were hundreds of printing presses operating in Europe,

manufacturing books on an unprecedented scale.

On one printing press,

you had two people working on it,

and in one day, they could make 2,500 prints.

That means that in, let's say, two weeks' time,

they could print a whole book in 1,250 copies.

And in the manuscript time,

it would take one scribe about a year

to produce one single copy of a text.

That's really an information revolution at the time.

And just as paper had made its way from the Islamic world

to Europe, printed books were soon traveling

in the other direction, as European printers set out

to serve Christian readers

living under Islamic rule in the Ottoman Empire.

It looks quite humble,

but this is a rather rare and precious specimen.

This is the first Arabic book printed with movable type.

It was printed in 1514 in Fano, Italy.

And this here is a Book of Hours printed in Arabic.

But the manuscript tradition in the Islamic world

was very different from that in Europe.

Instead of a modular script of separate letters,

Arabic was written in a cursive style

in which the letters in a word are all connected.

These connections are obligatory,

and readers would never have seen Arabic

written any other way.

You see, the Arabic script is much more than

simply a cursive script that connects letters together.

In fact, it's words that stack

and are interwoven across the line.

There, it is not simply a sequence of words,

but some words might be higher and lower,

the ends of words might weave into the beginnings of others,

and all of that is incredibly difficult to reproduce

with movable type.

These difficulties are readily apparent

in the printed Book of Hours.

You can see that we have two forms of the Arabic script

on a single page.

The first form is a recognizable calligraphic Arabic hand.

It's a cliché, a wooden block.

It's not movable type.

And so it would be recognizable

to any reader of Arabic as good Arabic.

But underneath it, you have a completely new invention.

It is the Arabic movable type script,

and it results from the adaptation,

the forced adaptation, of Arabic to the movable type environment,

making it closer to the logic of the Latin script.

And you can see here that the

words do not stack up

upon each other like the calligraphic hand.

The letters are all on one basic line.

And you can even see, if you look closely,

that the base line that connects the cursive letters together

is not complete and there are gaps

between the individual letters.

The well-trained scribe

I don't think would have recognized this as Arabic.

It was difficult for movable type to reproduce

the look of an Arabic manuscript,

and that made it hard to compete

with the well-established local book trade.

So although Ottoman printers were soon printing Hebrew

and Armenian alphabets,

it was more than two centuries

before the first Arabic print shop was established

in Istanbul in 1727.

What we have here is the first Arabic book

printed with movable type in the Muslim world,

about 200 years after the, the Book of Hours

that we've looked at previously.

This text shows a remarkable advance

in Arabic printing technology.

There are many more ligatures

that mimic the Arabic calligraphic hand.

Nevertheless, unlike in Europe,

movable type failed to capture the market,

and within 20 years, the printer was out of business.

After a short stint,

basically, printing technology died off.

And so we can wonder, why did printing never really take off?

And, well, the most obvious difference between

the first book printed using movable type

in the Muslim world and the Gutenberg Bible

is the book's contents... this is a dictionary.

This would have had a much more limited audience,

it wouldn't have been consumed by everyone,

and it wouldn't have been a book

that everyone would have had an interest in.

That book would have been the Koran,

but movable type, although improved,

was still not good enough

to reproduce the calligraphy of the Holy Book.

If you could have had affordable and mass-produced Korans,

I think you would've had a huge market for that.

The trouble is, they had to meet a certain quality.

You could not print a Koran like this.

This does not reproduce a manuscript,

it does not reproduce the format

of the Koran that the faithful were used to seeing.

So the most widely read and widely appreciated

Arabic book was never printed using movable type,

and that took a huge part of the market out.

Whereas Gutenberg printed the book, the Bible, that basically

everyone in the continent would have wanted.

So there's an irony.

Printing took off in Europe in large part

because Gutenberg could produce with movable type

a book that looked as if it had been written by hand.

And that was possible because he was printing the Latin alphabet.

If he'd been trying to print a different script,

he might never have succeeded.

That simple fact

lies behind a thousand-fold increase

in the availability of information,

an explosion of ideas that led directly

to the European scientific revolution,

the Industrial Revolution that followed,

and the world we live in today.

Pen and paper,

ink and alphabet...

these things are so familiar

as to be almost invisible.

But these are world-altering technologies.

Our history has been shaped

by the shape of the letters we write

and the means we use to write them.

Remember that next time you pick up a pencil.
