 The Roman soldiers are shown wearing generic armor and weapons resembling the type used in the first century AD, but the film is actually set in the fifth century AD, by which time Roman troops no longer wore leather armor and would have instead worn scale armor or chain mail.The film contains a scene, based on the final episode of Carl Sagan's "Cosmos", in which Christians burn the "Great Library of Alexandria", but the historical Library of Alexandria had actually ceased to exist in any recognizable form centuries before Hypatia was even born.The last references to anyone having held membership in the Mouseion (the larger research institute which contained the library) date to the 260s AD.
