Mykonos was named after the son or grandson of the god Apollo and a local hero. The island is said to be the location where the great battle between Zeus and the Titans took place. Hercules is believed to have killed the invincible giants by luring them here, away from their protection of Mount Olympus. Without their protection the giants became vincible and Hercules was able to kill them off. The large rocks all over Mykonos island are said to be the testicles of these petrified giants.
