History of the Peloponnesian War

The same winter, Hippocrates, setting out from Peloponnesus with ten galleys of Thurium, commanded by Dorieus, the son of Diogoras, with two others, and with one galley of Laconia and one of Syracuse, went to Cnidus. This city was now revolted from Tissaphernes;

and the Peloponnesians that lay at Miletus, hearing of it, commanded that, the one half of their galleys remaining for the guard of Cnidus, the other half should go about Triopium and help to bring in the ships which were to come from Egypt. This Triopium is a promontory of the territory of Cnidus, lying out in the sea and consecrated to Apollo.
