In the spring of 400 BC, roughly ten thousand Greek mercenaries stood on a promontory on the Black Sea coast and looked at a harbor that might have become a city. They had survived the Persian interior, the mountains of Armenia, the hostile Caucasian tribes, the long cold march toward the sea. They had reached it — the Black Sea, which they called the Pontus Euxinus, the Hospitable Sea — and here at Calpe, halfway between Byzantium and Heraclea Pontica, they rested. Xenophon, who led them and wrote down what happened, described the place in such precise detail that modern scholars can still find it: the narrow neck of land only 400 feet wide, the cliff falling straight to the sea, the port sheltered under the rock to the west, the fresh water source close to the beach. He saw it as a potential colony. His soldiers voted otherwise. They kept walking.

Calpe (Bithynia): Halfway Between Two Worlds

Photo credit Ucandairebaskani, CC BY-SA 4.0. Xenophon places Calpe about halfway between Byzantium and Heraclea Pontica — between the gateway to Europe and the main Greek city of the Pontic coast. That midpoint location gave the harbor a natural logic as a waystation for coastal traffic. Arrian, writing in the second centur...

The site of ancient Calpe is today identified with the area near Kerpe, a small coastal settlement in Kocaeli Province on the Black Sea coast of Turkey. The modern village carries none of the weight of the ancient description — it is a quiet stretch of coastline, fishing boats, a...
