Hypatia, daughter and pupil of Theon, enjoys the distinction of being the first known woman mathematician and the last of the ancient mathematicians. She assisted her father in the commentary on Ptolemy's Almagest and the revisions to Euclid's Elements. She supposedly wrote commentaries (now lost) on Diophantus's Arithmetica and Apollonius's Conic Sections. She is the last-known lecturer at Alexandria, where her teachings on mathematics and Neoplatonism, a philosophy she propounded, won for her the admiration of her students and the enmity of the Christians. Likely her works were among those burned in frequent pillages of libraries by Christian mobs and she was killed by one of the mobs around the year 415.
