What was the Library of Alexandria?

History By 1 min read

Quick answer

The Library of Alexandria was the most famous library of the ancient world, founded in Alexandria, Egypt, under the Ptolemaic kings in the early 3rd century BC. It aimed to collect every book in the known world, perhaps holding hundreds of thousands of scrolls. It wasn’t destroyed in one fire but declined over centuries.

Founded by Alexander’s successors

After Alexander the Great died in 323 BC, his general Ptolemy I took control of Egypt. Ptolemy I or his son Ptolemy II founded the Library as part of the Mouseion, a research institute dedicated to the Muses. Scholars lived there, paid by the king, to study and write.

How it collected books

Ships’ booksBooks found on ships in the harbor were copied; the library often kept the original
BorrowingIt famously borrowed Athens’ official copies of the great plays and never returned them, forfeiting a large deposit

Great minds of Alexandria

  • Euclid wrote his Elements, the basis of geometry for 2,000 years.
  • Eratosthenes, a chief librarian, estimated Earth’s circumference with impressive accuracy.
  • Callimachus created the Pinakes, one of the first library catalogs.
  • Scholars produced the Septuagint, a Greek translation of the Hebrew Bible.

How did it end?

EventEffect
48 BCJulius Caesar’s fire in Alexandria may have burned some books or warehouses
Later centuriesFunding fell and scholars were expelled under some rulers
AD 270sFighting destroyed the palace district
AD 391The Serapeum, a daughter library, was destroyed

Most historians say the Library faded through neglect and conflict, not a single dramatic blaze.

The modern library

Egypt opened the Bibliotheca Alexandrina in 2002, a huge modern library and cultural center near the ancient site, with a tilted, disc-shaped roof.
