Strabo Geography 16.3.5

[5] “Nearchus and Orthagoras relate, that an island Ogyris lies to the south, in the open sea, at the distance of 2000 stadia ¹ from Carmania. In this island is shown the sepulchre of Erythras, a large mound, planted with wild palms. He was king of the country, and the sea received its name from him. It is said that Mithropastes, the son of Arsites, satrap of Phrygia, pointed out these things to them. Mithropastes was banished by Darius, and resided in this island; he joined himself to those who had come down to the Persian Gulf, and hoped through their means to have an opportunity of returning to his own country.
