Library Of Alexandria - Elizabeth Cox
-
0:07 - 0:092,300 years ago,
-
0:09 - 0:12the rulers of Alexandria
set out to fulfill -
0:12 - 0:14one of humanity’s most audacious goals:
-
0:14 - 0:19to collect all the knowledge in the world
under one roof. -
0:19 - 0:20In its prime,
-
0:20 - 0:24the Library of Alexandria housed
an unprecedented number of scrolls -
0:24 - 0:27and attracted some of
the Greek world’s greatest minds. -
0:27 - 0:32But by the end of the 5th century CE,
the great library had vanished. -
0:32 - 0:35Many believed it was destroyed
in a catastrophic fire. -
0:35 - 0:39The truth of the library’s rise
and fall is much more complex. -
0:39 - 0:43The idea for the library came
from Alexander the Great. -
0:43 - 0:45After establishing himself as a conqueror,
-
0:45 - 0:48the former student of Aristotle
turned his attention -
0:48 - 0:53to building an empire of knowledge
headquartered in his namesake city. -
0:53 - 0:55He died before construction began,
-
0:55 - 0:57but his successor, Ptolemy I,
-
0:57 - 1:01executed Alexander’s plans
for a museum and library. -
1:01 - 1:04Located in the royal district of the city,
-
1:04 - 1:05the Library of Alexandria
-
1:05 - 1:08may have been built
with grand Hellenistic columns, -
1:08 - 1:10native Egyptian influences,
-
1:10 - 1:15or a unique blend of the two--there are
no surviving accounts of its architecture. -
1:15 - 1:20We do know it had lecture halls,
classrooms, and, of course, shelves. -
1:20 - 1:22As soon as the building was complete,
-
1:22 - 1:26Ptolemy I began to fill it with
primarily Greek and Egyptian scrolls. -
1:26 - 1:31He invited scholars to live
and study in Alexandria at his expense. -
1:31 - 1:34The library grew as they contributed
their own manuscripts, -
1:34 - 1:40but the rulers of Alexandria still wanted
a copy of every book in the world. -
1:40 - 1:44Luckily, Alexandria was a hub for ships
traveling through the Mediterranean. -
1:44 - 1:49Ptolemy III instituted a policy requiring
any ship that docked in Alexandria -
1:49 - 1:52to turn over its books for copying.
-
1:52 - 1:55Once the Library’s scribes
had duplicated the texts, -
1:55 - 1:59they kept the originals
and sent the copies back to the ships. -
1:59 - 2:02Hired book hunters also scoured
the Mediterranean -
2:02 - 2:04in search of new texts,
-
2:04 - 2:07and the rulers of Alexandria attempted
to quash rivals -
2:07 - 2:12by ending all exports of the Egyptian
papyrus used to make scrolls. -
2:12 - 2:16These efforts brought hundreds
of thousands of books to Alexandria. -
2:16 - 2:18As the library grew,
-
2:18 - 2:22it became possible to find information
on more subjects than ever before, -
2:22 - 2:27but also much more difficult to find
information on any specific subject. -
2:27 - 2:32Luckily, a scholar named Callimachus of
Cyrene set to work on a solution, -
2:32 - 2:34creating the pinakes,
-
2:34 - 2:37a 120-volume catalog
of the library’s contents, -
2:37 - 2:39the first of its kind.
-
2:39 - 2:41Using the pinakes,
-
2:41 - 2:44others were able to navigate
the Library’s swelling collection. -
2:44 - 2:47They made some astounding discoveries.
-
2:47 - 2:491,600 years before Columbus set sail,
-
2:49 - 2:53Eratosthenes not only realized
the earth was round, -
2:53 - 2:55but calculated its circumference
and diameter -
2:55 - 2:58within a few miles of their actual size.
-
2:58 - 3:01Heron of Alexandria created
the world’s first steam engine -
3:01 - 3:03over a thousand years before
-
3:03 - 3:07it was finally reinvented during
the Industrial Revolution. -
3:07 - 3:14For about 300 years after its founding
in 283 BCE, the library thrived. -
3:14 - 3:19But then, in 48 BCE, Julius Caesar
laid siege to Alexandria -
3:19 - 3:22and set the ships in the harbor on fire.
-
3:22 - 3:27For years, scholars believed the library
burned as the blaze spread into the city. -
3:27 - 3:30It's possible the fire destroyed
part of the sprawling collection, -
3:30 - 3:32but we know from ancient writings
-
3:32 - 3:37that scholars continued to visit
the library for centuries after the siege. -
3:37 - 3:41Ultimately, the library slowly disappeared
as the city changed from Greek, -
3:41 - 3:42to Roman,
-
3:42 - 3:43Christian,
-
3:43 - 3:45and eventually Muslim hands.
-
3:45 - 3:48Each new set of rulers viewed
its contents as a threat -
3:48 - 3:51rather than a source of pride.
-
3:51 - 3:53In 415 CE,
-
3:53 - 3:56the Christian rulers even had
a mathematician named Hypatia -
3:56 - 4:00murdered for studying
the library’s ancient Greek texts, -
4:00 - 4:02which they viewed as blasphemous.
-
4:02 - 4:07Though the Library of Alexandria
and its countless texts are long gone, -
4:07 - 4:10we’re still grappling
with the best ways to collect, -
4:10 - 4:11access,
-
4:11 - 4:13and preserve our knowledge.
-
4:13 - 4:15There’s more information available today
-
4:15 - 4:17and more advanced technology
to preserve it, -
4:17 - 4:19though we can’t know for sure
-
4:19 - 4:22that our digital archives
will be more resistant to destruction -
4:22 - 4:26than Alexandria’s ink and paper scrolls.
-
4:26 - 4:29And even if our reservoirs of knowledge
are physically secure, -
4:29 - 4:33they will still have to resist
the more insidious forces -
4:33 - 4:35that tore the library apart:
-
4:35 - 4:36fear of knowledge,
-
4:36 - 4:40and the arrogant belief
that the past is obsolete. -
4:40 - 4:44The difference is that, this time,
we know what to prepare for.
