Hypatia, often called Hypatia of Alexandria, was a Greek mathematician, astronomer and philosopher in Egypt, then a part of the Eastern Roman Empire. She was the head of the Neoplatonic school at Alexandria, where she taught philosophy and astronomy. According to contemporary sources, Hypatia was murdered by a Christian mob after being accused of exacerbating a conflict between two prominent figures in Alexandria: the governor Orestes and the Bishop of Alexandria. For some historians, Hypatia’s death symbolized the end of Classical antiquity. She was born born c. AD 350-370 and died in 415.
