Erm... except that really happened to Hypatia of Alexandria.
Not as they showed it. In fact, the ONLY thing they got right is that Hypatia was a philosopher, and she was lynched. That's it.
Hypatia was a Neo-platonist, and had utterly no problem with the Christian Church. She wasn't some Psuedo-Athiestic Humanist like the movie presents her. She had many Christian students, and even a few
Bishops included themselves in her circle of friends.
The likes of Augustine and Ambrose were major supporters of philosophy, including Neo-Platonism. Roman Christians LOVED the Greek classics, and went to extensive lengths to preserve them, which is why we still have them today.
Hypatia wasn't even killed for religious reasons! She was caught in the middle of a power struggle between the Bishop of Alexandria and the Governor of Egypt. The governor had sent some of his supporters to attack some of the Bishops, and they retaliated. Hypatia was one of the governors supporters, and she tragically was one of the targets of that retaliation. She wasn't killed for being an Apostate, however, she was killed for supporting the 'wrong' side in a political struggle.
The thing about the burning down the Library of Alexandria is complete and utter nonsense. You know why?
Because Julius Caesar destroyed it in 48 BC, when he defended Cleopatra from her brother's attempt to seize power. It was never rebuilt.
It is just slander based upon the writings of Edward Gibbon, who notoriously just pulled stuff out of his ass when it suited his agenda.
