Who was the earliest female philosopher?

The first outstanding female mathematician, astronomer and philosopher in the world

At the end of the Eastern Roman era, a female mathematician, astronomer and philosopher appeared in Alexandria, North Africa. She was praised for her talent, beauty, eloquence and morality. Her name was Hipatia (AD 370 ~ 4 15). She is the daughter of mathematician and astronomer Theon. (Theon is quite famous. His fame comes from Euclid's Elements of Geometry, Ptolemy's Masterpieces of Astronomy and his Annotated Convenient Books, all of which are quite complete and have brought influence to later generations. He himself is a less creative scholar. )
