The Library of Alexandria was a research center that held one million books by the time of Jesus.
In March of 415 C.E., on a sunny day in the holy season of Lent, Cyril of Alexandria, the most powerful Christian theologian in the world, murdered Hypatia, the most famous Greco-Roman philosopher of the time. Hypatia was slaughtered like an animal in the church of Caesarion, formerly a sanctuary of emperor worship.1 Cyril may not have been among the gang that pulled Hypatia from her chariot, tearing off her clothes and slashing her with shards of broken tiles, but her murder was surely done under his authority and with his approval.
