Son of the Titan Astraeus and Eos and god of the wind of the west and the spring. His wife was Iris and brothers Boreas (north wind) and Notus (south wind).

Zephyrus loved Apollo, and killed his rival Hyacintos when the god had shown interest in him. When the two were throwing discuses, Zephyrus blew the discus in Hyacinthos direction, killing him when it hit his head.

It was also Zephyrus who was the only wind left, when Aeolus gave Odysseus a sack with all the winds. Thanks to this western wind, the hero and his men reached Ithaca in only ten days
