 The population was very small in ancient times and, except for the brief mentions in Herodotus and Pausanias, left little or no record in the history of those times.It is clear that Hydra was populated during the Byzantine era, as vases and coins have been discovered in the area of Episkopi.However, it appears that the island again lost its population during the Latin Empire of Constantinople as its inhabitants fled the pirate depredations.
