Phaethusa is a Thrinacian Sun Nymph in Greek Mythology, who was tasked with guarding Helios' cattle on the island of Thrinacia with Lampetia.
Genealogy and Family[]
Phaethusa is a daughter of the Titan God of the sun, Helios and Neaera, possibly an Oceanid goddess. She was born alongside a twin sister, Lampetia. Her other siblings include The Heliades, The Heliadae, Electryone and Phaethon.
Story[]
Their mother, Neaera, took her and Lampetia to the island of Thrinacia where they guarded their father's cattle. She carried a copper staff with which she tended to her father's herd of sheep with. She is sometimes listed as among the Heliades, daughters of Helios and Clymene who mourned for their brother Phaethon and were transformed into poplar trees. In the Argonautica however, set explicitly after Phaethon's death, she and her sister are still tending to their father's flock.
