island received this name for the same reason. The island was also called Oche, and the largest of the mountains there bears the same name. It was also named Ellopia, after Ellops the son of Ion. Some say he was the brother of Aiclus and Cothus; he is also said to have founded Ellopia—a place in the region called Horia, in Histiaeotis near the mountain Telethrius—and to have added to his territory Histiaia, Periada, Cerinthus, Aedepsus, and Orobiae, in which there was an oracle that was most truthful; there was also an oracle of Apollo Selinuntius. The Ellopians migrated to Histiaia and expanded the city, having been forced to do so by the tyrant Philistides after the battle of Leuctra. Demosthenes says that Philistides was established as tyrant of the Oreitae by Philip; for this is what the Histiaeans were later called, and the city was called Oreus instead of Histiaia. Some say that Histiaia was colonized by Athenians from the deme of the Histiaeans, just as Eretria was from that of the Eretrians. Theopompus says that when Pericles was overpowering Euboea, the Histiaeans moved to Macedonia by agreement, and two thousand Athenians came and settled in Oreus, which had previously been a deme of the Histiaeans.
