NisyrosAs we approach Nisyros by boat we cannot fail to be deeply impressed by the image that emerges before our eyes: perfectly white houses, dense greenery, and the colors of the volcanic soil. According to ancient mythology Poseidon, helping Zeus in his battle against the Titans, chased the fearful giant Polybotis over land and seas. When Poseidon reached the island of Kos he broke of a piece of the island with his mighty trident and throwing it at Polybotis he buried him under it. This broken off piece of Kos became the island of Nisyros. The volcano was created over the mouth of Polybotis and the constant rumblings are the chest sighs of the buried titan.
