Hypatia (b. ca. AD 350–370, d. March 415) was an Egyptian Neoplatonist philosopher who was the first notable woman in mathematics. As head of the Platonist school at Alexandria, she also taught philosophy and astronomy. As a Neoplatonist philosopher, she belonged to the mathematic tradition of the Academy of Athens, as represented by Eudoxus of Cnidus; she was of the intellectual school of the 3rd century thinker Plotinus, which encouraged logic and mathematical study in place of empirical enquiry and strongly encouraged law in place of nature. Hypatia lived in Roman Egypt, and was murdered by a Christian mob which accused her of causing religious turmoil. Kathleen Wilder proposes that the murder of Hypatia marked the end of Classical antiquity, while Maria Dzielska and Christian Wildberg note that Hellenistic philosophy continued to flourish in the 5th and 6th centuries, and perhaps until the age of Justinian.
