The Bibliotheca (Ancient Greek: ΒΙΒΛΙΟ&thΗήΚΗ Bibliothēkē, "Library"), also known as the Bibliotheca of Pseudo-Apollodorus, is a compendium of Greek myths and heroic legends, arranged in three books, generally dated to the first or second century AD.The author was traditionally thought to be Apollodorus of Athens, but that attribution is now regarded as false, and so "Pseudo-" was added to ApollodorusThe Bibliotheca has been called "the most valuable mythographical work that has come down from ancient times". An epigram recorded by the important intellectual Patriarch Photius I of Constantinople 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 cyc≤ but look in me and you will find in me all that the world contains'.The brief and unadorned accounts of myth in the Bibliotheca have led some commentators to suggest that even its complete sections are an epitome of a lost work.
