Hypatia, a mathematician, astronomer and a philosopher, is a symbol for generations
From Little Journeys to the Homes of Great Teachers: Hypatia, by Elbert Hubbard, 1908
Editing Book III of Ptolemy's Almagest
Theon of Alexandria, Hypatia’s father, was a remarkable mathematician and philosopher in his own right. His efforts in preserving Euclid’s Elements are highly regarded to this day. Apart from this, Theon was deeply involved in writing extensive commentaries on Ptolemy’s works- Almagest and Handy Tables.
His daughter, Hypatia, continued his work and this proved beneficial in the preservation of the Greek mathematical and astronomical legacy. She built upon her father’s third book which contained the commentary on Almagest. Apart from these, Hypatia is credited for writing impactful commentaries on Apollonius of Perga’s Conics, as well as Diophantus’ Arithmetic. It is believed that her works aimed at interpolating her father’s theories and commentaries with the challenging areas of mathematics and philosophy of her time.

Hypatia used to build astrolabes. An astrolabe was used to calculate date and time based on the positions of the planets and stars. It can also be used to calculate stars and planets positions on any given date.
