Person

Hypatia

Hypatia of Alexandria (c. AD 355-415) was the leading mathematician, astronomer, and Neoplatonic philosopher of her generation, head of the Neoplatonic school at Alexandria, and a public intellectual honored across the city. She is remembered today as much for her brutal murder by a Christian mob in 415 as for her scholarship, and her death has become a heavily mythologized flashpoint in debates over religion and violence. The historical assessment of that event is treated in the Hypatia Murder Objection Defeater; this page covers her life and thought.

Biographical sketch

Daughter and pupil of Theon of Alexandria, the mathematician and last recorded member of the Alexandrian Museum; she collaborated on and extended his work.
Rose to lead the Neoplatonic school at Alexandria, teaching mathematics, astronomy, and philosophy to a circle of elite students, pagan and Christian alike.
Held in high civic esteem; the prefect Orestes and other notables sought her counsel, an entanglement in city politics that would prove fatal.
Murdered in March 415 during the factional conflict between Orestes and Patriarch Cyril (see Cyril of Alexandria and the Hypatia Murder Objection Defeater).

Thought and work

Mathematics. She is credited (largely through later testimony and the Suda) with commentaries on Diophantus's Arithmetica, the Conics of Apollonius of Perga, and Ptolemy's astronomical tables, editing, clarifying, and teaching the mathematical canon rather than founding a new system.
Astronomy and instruments. Letters from her student Synesius of Cyrene credit her circle with practical knowledge of the astrolabe and a hydrometer, situating her in the applied astronomical tradition.
Neoplatonism. Philosophically she stood in the Plotinian-to-Iamblichan Neoplatonic lineage, teaching the ascent of the soul toward the One. Her Neoplatonism was reportedly of a more restrained, mathematically inflected cast than the ritual-heavy theurgy of some contemporaries, part of why she could hold Christian students.

Students and reception

Her best-documented pupil, Synesius of Cyrene, became a Christian bishop (of Ptolemais) and wrote her a series of affectionate, deferential letters, direct evidence that her school was not a pagan-versus-Christian battleground. Pagan (Damascius) and Christian (Socrates Scholasticus) sources alike portray her as learned, virtuous, and widely respected, which is part of what made her death so shocking to contemporaries.

The legend

From Edward Gibbon through Carl Sagan's Cosmos to the 2009 film Agora, Hypatia has been recast as "the martyr of reason," her death made to symbolize the triumph of Christian fanaticism over classical learning and the destruction of the Library of Alexandria. Modern scholarship (Maria Dzielska, Hypatia of Alexandria, 1995; Edward Watts, Hypatia, 2017) has substantially corrected this: the murder was rooted in Alexandrian power politics, not a war on science, and it neither ended classical learning nor destroyed the (already long-declined) Library. The Hypatia Murder Objection Defeater works through the history and the apologetic implications.
