Are you sure about that? Kozachka says the Philistines burned the library at Alexandria.
It has been blamed on phillistines, romans, muslims, and a pyromaniac librarian from Thebes that couldn't stomach competition..
There are also rumours that the Alexandrian Library's festival of jugglers with flaming torches may have caused a few conflagurations as well..
My best guess is the Alexandrian practice of tying oily rags to a cat's tail and setting them on fire during the full moon was the actual culprit...
