Tinos was named after King Tino, the first settler of the island and leader of a group of Ionians from Cariati of Asia Minor, who lived here in prehistoric times. A local tradition attributes the name to Princess Tinos.
According to a legend of Greek mythology, the god of the sea, Poseidon sent to this island a swarm of storks in order to relieve the ancient inhabitants of the many snakes that had almost invaded it. Thus, the inhabitants, grateful to Poseidon and his mythical wife, Amphitrite, built two temples to which they honored them as their patrons.
