Helios
The sun god, whose sacred cattle become a fatal taboo on the voyage.

Overview
Helios is the sun god. The Theogony places him in the Titan genealogy as a child of Hyperion and Theia alongside Selene and Eos. The Odyssey shows his rights being enforced through the cattle of Thrinacia, guarded by his daughters Lampetie and Phaethousa. Both Tiresias and Circe warn Odysseus not to harm them. When the crew slaughter cattle while he sleeps, Lampetie reports the act to her father; Helios demands punishment from Zeus and threatens to shine among the dead if denied redress, so Zeus promises to destroy the ship with a thunderbolt. Genealogy establishes his cosmic place, while the cattle episode links sacred property, witness, appeal and divine punishment.
