It didn't help that she was a close friend of the pagan Prefect Orestes. The Christian Archbishop of Alexandria, Cyril, blamed Hypatia for keeping Orestes from the "true faith." Cyril also viewed her as an obstacle for those who might have accepted Christianity but for her charisma, charm, and excellence in making difficult mathematical and philosophical concepts understandable – concepts that contradicted the teachings of the relatively new church.
Ultimately, the age-old conflict between faith and reason cost Hypatia her life. While on her way home from delivering her daily lectures at the university in 415 C.E., she was attacked by Christian zealots. They dragged her to the front of a church, stripped her naked, beat her, then butchered and burned her body. Soon after, Cyril ordered the University of Alexandria sacked and burned, leading to a mass exodus of intellectuals and artists from the newly Christianized city of Alexandria.
Hypatia's death is recognized as a watershed moment in history, delineating the classical age from the age of Christianity. Alexandria, which immediately fell into decline, waned as a center of culture and learning.
Hypatia’s untimely loss remains a symbol of the tragic cost of religious intolerance.
Hypatia dedicated herself to reason and scholarship in the face of prejudice and ignorance. She was the first woman known to history to make a contribution to the advancement of mathematics. Today she is a powerful feminist icon and affirmation for female intellectual ability. This is why she's a Time Traveler Tours #HistoryHero. Many thanks to TTT&T followers, Nivrith and Teresa Robeson, for bringing Hypatia to our attention.
