In Greek mythology, Lampetia (Ancient Greek: , romanized: Lampetí? or Ancient Greek: , romanized: Lampetía, lit. 'shining') was the daughter of Helios and Neaera; she was the personification of light. Her sister, Phaethusa, and she were taken by their mother to guard the cattle and sheep of Thrinacia. She looked after 700 animals in total. She ran to her father when Odysseus' men slaughtered and sacrificed some of his ageless and deathless cattle. Her father, Helios, was enraged and asked the gods to avenge the deaths of his cattle, threatening to bring sunlight to the Underworld if the men were not punished. Zeus then sent a lightning bolt down and a storm, killing all of Odysseus' men, a doom that was portended by the meat writhing and lowing on the spits.
