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 off 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 sighs of the buried titan! The name of the island possibly derives from pre Hellenic aegean place names. Homer refers to the cooperation of the Nysirian islander in the Trojan expedition. The inhabitants of Nissyros worshipped Delfinios Apollo as well as the sea god Poseidon, a temple to whom was once located where Pali are today. The historical fortunes of Nisyros is common with the fortunes of the
other islands of the south eastern Aegean. Pirates harboured in the area until the Knights of Rhodes took over the island in 1312. In 1522 the Turks occupied Nissiros and in 1912 the Italians took over and with the end of World War II Nissyros was incorporated to Greece.
