Head of the Neoplatonic school in Alexandria, Hypatia taught geometry, astronomy, and philosophy to Christians and pagans alike. She stands as an enduring symbol of reason and intellectual courage.
Life
Daughter of the mathematician Theon of Alexandria, Hypatia grew up in the great library city as it entered its final century of glory. She became the last known steward of a lineage of learning that stretched back to Euclid.
She lectured publicly on Plato and Aristotle, corresponded with statesmen, and was consulted by governors. In an age of intensifying religious violence, she refused to abandon philosophy for any dogma — and was ultimately murdered by a mob for it.
