Hyacinth or Hyacinthus was one of Apollo's male lovers. He was a Spartan prince, beautiful and athletic. The pair was practicing throwing the discus when a discus thrown by Apollo was blown off course by the jealous Zephyrus and struck Hyacinthus in the head, killing him instantly. Apollo is said to be filled with grief: out of Hyacinthus' blood, Apollo created a flower named after him as a memorial to his death, and his tears stained the flower petals with the interjection αἰαῖ, meaning alas. The Festival of Hyacinthus was a celebration of Sparta.
