Personal Life of Hypatia

Hypatia was the daughter of mathematician and astronomer, Theon of Alexandria. Not much is known about her mother. She was the only child of her parents, and Theon educated her himself.

As Hypatia reached her adulthood, she had surpassed her father in both mathematics and philosophy. She became a renowned scholar in the city and took her father's place as the head of Platonic school, a modern university.

Hypatia taught students from all over the Mediterranean. She also taught them the writings of Plato and Aristotle. She spoke amongst the assembly of men, which shows her extraordinary dignity and virtue. She was often described as a charismatic teacher.

While Hypatia was considered a Pagan, a traditional roman belief before Christianity, she worshipped no particular diety. Her ideas can be connected to multiple religious belief systems.

Contributions of Hypatia in the field of Mathematics

Hypatia refined several scientific instruments, wrote math textbooks, and developed a more efficient long division method. Hypatia wrote a piece on Diophantus's thirteen volume Arithmetica, which contains 100 mathematical problems, whose solutions are proposed using algebra. She also wrote an article on conic sections, but these writings have been lost in the hole of time.

Hypatia also constructed an Astrolabe, which is a device used to calculate the date and time according to the positions of stars and planets. She also built a Hydrometer, a tool used to determine densities of fluids.

It is not evident that she took part in any original mathematical research. However, she assisted her father in producing a new version of Euclid’s Elements.

Hypatia was a Neoplatonist, believing that mathematics has a spiritual aspect, divided among the four branches of arithmetic, geometry, astronomy, and music. She thought that the numbers are the sacred language of the universe.

How did Hypatia die?

Christianity was on the rise and became the Empire's state religion. The local archbishop Cyril got political powers and commanded Pagan temples' destruction and the harassment of the Jewish population. There was a bitter religious conflict between Christians, Jews, and Pagans.

Cyril encroached on the secular authority of the Roman governor Orestes, which led to a prolonged public quarrel between the two men. As Hypatia was considered wise and impartial, Orestes consulted her, and she advised him to act with fairness.

When Cyril's monks badly injured Orestes in a riot, he had their leader tortured to death. Cyril and his followers blamed Hypatia for witchcraft and turning Orestus against Christianity.

One day when Hypatia was traveling through the city, a violent Christian mob attacked her and dragged her out of her carriage, brutally murdering her and dismembering her body.

Hypatia's death was a turning point in the politics of Alexandria. In the wake of her murder, philosophers, greek and Romans fled the city, and the city's role as the center of learning declined. She was being called a 'martyr of philosophy'.


The affair of her death made Hypatia a powerful feminist symbol. She became an inspiration for the intellectual endeavor she had in the face of the ignorance of prejudice. Hypatia's contribution to mathematics and philosophy was enough to leave a great legacy behind and preserve her name. Still, sadly, the manner of her death added to it with even greater emphasis.
