According to various archeological findings in the place Episkopi of Hydra, scientists have concluded that the emigration to the island had begun long before the Homeric period, meaning the after Neolithic time (3000 - 2600 B.C.). Hydra didn't manage, to the centuries that followed, to evolve in a place socially and historically capable of being.
Hydria, as Herodotus used to call the island of Hydra, around the 13th century, is becoming the place of Driops farmers, fishermen and shepherds, who used to live to the Parnassus and Oiti. Two centuries later, with the descent of Dorians, Driops are disappearing and so the life in the island.
During Archaic times, Hydra didn't have to offer anything of Historical value. The island was probably under the command of the king of Mycenae , then it was bought from Hermions until 525 B.C and then again it was bought from political refugees from Samos to be given to trizinians, who wanted the island for farming and forager.
A small number of Historians make references to Hydra. Among them are Herodotus, Ptolemaios the Geographer, Pausanias and the lexicographers, Stefanos the Byzantios and Isixios.
