Hypatia: Philosopher at the Crossroads
Hypatia taught mathematics in a city tearing itself apart—her lecture hall ringed by religious mobs.

Scholar in the Storm
Hypatia drew crowds for her discussions of geometry and astronomy. She was one of very few women with public authority in a city where ideology was now a matter of life or death.
When Ideas Became Dangerous
Alexandria was fracturing—Christian zeal competing with ancient traditions. Hypatia tried to bridge worlds. Instead, her murder in 415 CE marked the end of something: the free exchange of ideas, trampled by violence.
Hypatia was no ivory-tower academic. She was a civic leader, mathematician, and pagan in Christianizing Alexandria. Her death is a flashpoint: the old world of philosophical debate giving way to new forces, less tolerant of ambiguity and dissent.
