Anabasis

During that day they bivouacked where they were, upon the beach by the harbour. Now this place which is called Calpe Harbour is situated in Thrace-in-Asia; and this portion of Thrace begins at the mouth of the Euxine and extends as far as Heracleia, being on the right as one sails into the Euxine.

It is a long day’s journey for a trireme to row from Byzantium to Heracleia, and between the two places there is no other city, either friendly or Greek, only Bithynian Thracians; and they are said to abuse outrageously any Greeks they may find shipwrecked or may capture in any other way.

As for Calpe Harbour, it lies midway of the voyage between Heracleia and Byzantium and is a bit of land jutting out into the sea, the part of it which extends seaward being a precipitous mass of rock, not less than twenty fathoms high at its lowest point, and the isthmus which connects this head with the mainland being about four plethra in width; and the space to the seaward of the isthmus is large enough for ten thousand people to dwell in.

At the very foot of the rock there is a harbour whose beach faces toward the west, and an abundantly flowing spring of fresh water close to the shore of the sea and commanded by the headland. There is also a great deal of timber of various sorts, but an especially large amount of fine ship-timber, on the very shore of the sea.

The ridge extends back into the interior for about twenty stadia, and this stretch is deep-soiled and free from stones, while the land bordering the coast is thickly covered for a distance of more than twenty stadia with an abundance of heavy timber of all sorts.

The rest of the region is fair and extensive, and contains many inhabited villages; for the land produces barley, wheat, beans of all kinds, millet and sesame, a sufficient quantity of figs, an abundance of grapes which yield a good sweet wine, and in fact everything except olives.
