Circe (Κίρκη) is the Greek sorceress of the Odyssey — daughter of the sun god Helios, who turned Odysseus's men into pigs on her island Aeaea. Her name derives from kirkos, meaning "hawk."
Madeline Miller's 2018 novel Circe brought a major modern revival to the name.
Circe reduces to eight — the number of Greek sorcery.
