Portrait of Hypatia

Hypatia

Neoplatonist

Born c. 355 CE, Alexandria

Died 415 CE, Alexandria

Mathematician, astronomer, and the last great teacher of Alexandria, killed for standing at the center of its conflicts.

Hypatia led the Neoplatonist school of Alexandria, lectured on Plato and Aristotle to students who came from across the Mediterranean, and wrote commentaries on mathematics and astronomy that were used for centuries. She designed instruments, an astrolabe and a hydrometer among them, and held a position of unusual public authority for a woman of her age. In 415 she was caught in the violent politics between the city's prefect and its bishop and was murdered by a mob. Her death is often read as a closing of the ancient mind, though the truth is more tangled and more human.

Hypatia lectures in Alexandria with an astrolabe and geometric diagrams, star charts on the walls, students with scrolls in columned light.
Mathematics and philosophy at the city's edge.
