Lampetia (Λαμπετίη) is from the Greek lampō (to shine). One of the **Heliades, daughters of Helios the Sun** — with her sister Phaethusa, **she kept Helios's sacred cattle on the island of Thrinacia**. When Odysseus's crew slaughtered the cattle, she reported the crime to her father, who demanded their destruction.
Featured in Homer's Odyssey Book 12.
Lampetia reduces to five — the number of Heliade.
