Hypatia of Hypatia (c. 360–415 CE): Hypatia, a prominent Neoplatonist philosopher and mathematician in ancient Alexandria, is sometimes associated with Gnostic thought due to her interest in esoteric and mystical subjects. While she wasn't a Gnostic herself, her intellectual pursuits intersected with Gnostic ideas, and she is often regarded as an inspirational figure in the development of mystical and esoteric traditions.
