Lampetia is one of Helios’s daughters and Circe’s half-sister. Like her sister Phaethousa, Lampetia is a caretaker of Helios’s sacred cattle. She is one of Helios’s most beautiful children and she, just like the other gods, is obsessed with perfection and beauty in a very vapid way. She suggests that Circe never speak in order to hide her ugly voice.
