Strabo, Geography

Then to Cnidus, with two harbors, one of which can be closed, can receive triremes, and is a naval station for twenty ships. Off it lies an island which is approximately seven stadia in circuit, rises high, is theatre-like, is connected by moles with the mainland, and in a way makes Cnidus a double city, for a large part of its people live on the island, which shelters both harbors. Opposite it, in the high sea, is Nisyrus. Notable Cnidians were: first, Eudoxus the mathematician, one of the comrades of Plato; then Agatharchides, one of the Peripatetics, a historian; and, in my own time, Theopompus, the friend of the deified Caesar, being a man of great influence with him, and his son Artemidorus. Thence, also, came Ctesias, who served Artaxerxes as physician and wrote the works entitled Assyrica and Persica. Then, after Cnidus, one comes to Ceramus and Bargasa, small towns situated above the sea.
