Zephyr or Zephir God in Floral Witchcraft is the God of the West wind. He is one of the sons of Eos and Astreu, being his brothers Boreas, Notus and Eurus. He was married to Iris and lived in a Thrace cave. In Roman mythology, this god was associated with Favonius. The wind myth Zephyr says that this fertilized the mares in a certain region of Lusitania making the horses in this area unusually fast. It appears in the Ode Maritime of Avieno.
Another of the myths in which Zephyr appears most prominently is that of Jacinto, a handsome and athletic Spartan prince. Zephyr fell in love with Jacintus and courted him, as did Apollo. Both competed for his love, which came to choose Apollo, making Zephyr go crazy with jealousy. Later, when he surprised them by practicing the release of the disc, Zephyr blew a gust of wind over them, causing the disc to hit Jacintus on the head as he fell.
When Jacintus died, Apollo created the flower of the same name with his blood. In Psyche's story it was Zephyr who served Eros by transporting Psyche to his home.
