Hypatia, (born c. 355 CE/AD—died March 415, Alexandria), mathematician, astronomer, and philosopher who lived in a very turbulent era in Alexandria’s history. She is the earliest female mathematician of whose life and work reasonably detailed knowledge exists.
Hypatia was the daughter of Theon of Alexandria, himself a mathematician and astronomer and the last attested member of the Alexandrian Museum (see Researcher’s Note: Hypatia’s birth date). Theon is best remembered for the part he played in the preservation of Euclid’s Elements, but he also wrote extensively, commenting on Ptolemy’s Almagest and Handy Tables. Hypatia continued his program, which was essentially a determined effort to preserve the Greek mathematical and astronomical heritage in extremely difficult times. She is credited with commentaries on Apollonius of Perga’s Conics (geometry) and Diophantus of Alexandria’s Arithmetic (number theory), as well as an astronomical table (possibly a revised version of Book III of her father’s commentary on the Almagest). These works, the only ones she is listed as having written, have been lost, although there have been attempts to reconstruct aspects of them. In producing her commentaries on Apollonius and Diophantus, she was pushing the program initiated by her father into more recent and more difficult areas.
She was, in her time, the world’s leading mathematician and astronomer, the only woman for whom such claim can be made. She was also a popular teacher and lecturer on philosophical topics of a less-specialist nature, attracting many loyal students and large audiences. Her philosophy was Neoplatonist and was thus seen as “pagan” at a time of bitter religious conflict between Christians (both orthodox and “heretical”), Jews, and pagans. Her Neoplatonism was concerned with the approach to the One, an underlying reality partially accessible via the human power of abstraction from the Platonic forms, themselves abstractions from the world of everyday reality. Her philosophy also led her to embrace a life of dedicated virginity.
With the deaths of Synesius and Theophilus and the accession of Cyril to the bishopric of Alexandria, however, this climate of tolerance lapsed, and shortly afterward Hypatia became the victim of a particularly brutal murder at the hands of a gang of Christian zealots.
Carl Sagan on Hypatia:
The last scientist who worked in the Library was a mathematician, astronomer, physicist and the head of the Neoplatonic school of philosophy--an extraordinary range of accomplishments for any individual in any age. Her name was Hypatia. She was born in Alexandria in 370. At a time when women had few options, and were treated as property, Hypatia moved freely and unselfconsciously through traditional male domains. By all accounts she was a great beauty. She had many suitors but rejected all offers of marriage. The Alexandria of Hypatia's time--by then long under Roman rule--was a city under grave strain. Slavery had sapped classical civilization of its vitality. The growing Christian Church was consolidating its power and attempting to eradicate pagan influence and culture. Hypatia stood at the epicenter of these mighty social forces. Cyril, the Archbishop of Alexandria, despised her because of her close friendship with the Roman govenor, and because she was a symbol of learning and science, which were largely identified by the early Church with paganism. In great personal danger, she continued to teach and publish, until, in the year 415, on her way to work she was set upon by a fanatical mob of Cyril's parishoners. They dragged her from her chariot, tore off her clothes, and, armed with abalone shells, flayed her flesh from her bones. Her remains were burned, her works obliterated, her name forgotten. Cyril was made a saint."
"The glory of the Alexandrian Library is a dim memory. Its last remnants were destroyed soon after Hypatia's death. It was as if the entire civilization had undergone some self-inflicted brain surgery, and most of its memories, discoveries, ideas and passions were extinguished irrevocably. The loss was incalculable. In some cases, we know only the tantalizing titles of the works that were destroyed. In most cases, we know that of the 123 plays of Sophocles in the Library, only seven survived. One of those seven is Oedipus Rex. Similar numbers apply to the works of Aeschylys and Euripedes. It is a little as if the only surviving works of a man named William Shakespeare were Cariolanus and a A Winter's Tale, but we had heard that he had written certain other plays, unknown to us but apparently prized in his time, works entitled Hamlet, Macbeth, Julius Caesar, King Lear, Romeo and Juliet."
"Of the physical contents of that glorious Library not a single scroll remains. In modern Alexandria few people have a keen appreciation, much less detailed knowledge, of the Alexandrian Library or of the great Egyptian civilization that preceded it for thousands of years.
