The Bibliotheca ( Bibliotheke, "Library") is a compendium of myths and heroic legends, arranged in three books, generally dated to the first or second centuries AD. It was known traditionally as the Library of Apollodorus, but the attribution is now regarded as false. The Bibliotheca has been called "the most valuable mythographical work that has come down from ancient times". An epigram recorded by Photius expressed its purpose:

It has the following not ungraceful epigram: 'Draw your knowledge of the past from me and read the ancient tales of learned lore. Look neither at the page of Homer, nor of elegy, nor tragic muse, nor epic strain. Seek not the vaunted verse of the cycle; but look in me and you will find in me all that the world contains'.
