Zephyros

Zephyrus (Favonius in Latin ) is the god and personification of the West Wind. The most called-on wind in myth, Zephyrus is believed to have inhabited a cave in Thrace during Greek times. His mother is Eos (Aurora in Latin), goddess of dawn, while his father is Astraeus, the Titan god of astronomy. One of the anemoi (directional winds) with his brothers Boreas (the North Wind), Eurus (the East Wind), and Notus (the South Wind); Zephyrus abducted the goddess Chloris (Flora in Latin) to be his wife and gave her power over flowers, he fathered Carpus (fruit) with her.

Mythology
Zephyrus was most famous for his rivalry with Apollo for the love of Hyacinth. One day he spied on them and saw the pair playing discus throw, Zephyrus got jealous, and blew a gust of wind at them, striking the boy in the head with the falling discus, thus killing him. In grief of his death, Apollo created the Hyacinth plant with his blood.

The Battle of the Labyrinth
Annabeth tells Percy that she was sent down from Olympus on Zephyrus by her mother, Athena in a golden cradle, to her father to be raised by him. Presumably this is how the children of Athena are generally sent to men she favors.

Favonius
As Zephyrus' Roman form, Favonius, he becomes more warlike and mitirialistic.
