Flourished 4th–3rd century B.C.E., Athens, ancient Greece
Recent scholars have identified two female philosophers named Perictyone (Perictione) in ancient Greece: Perictyone I, author of On the Harmony of Women (circa 425–300 B.C.E.), and Perictyone II, author of On Wisdom (ca. 300–200 B.C.E.). Both were Neo-Pythagoreans, followers of the ancient Greek philosopher and mathematician Pythagoras. At one time, it was thought that Perictyone I was the mother of Plato, but this is unlikely.
