Cerasus or Kerasous (Ancient Greek: Κερασοῦς) was a town of ancient Pontus, on the Black Sea coast, a little to the west of Trapezus.
[1] The Ten Thousand, in their retreat, came to Trapezus, and leaving Trapezus, "they arrive on the third day at Cerasus, an Hellenic city on the sea, a colony of the Sinopeis, in Colchis.
"[2] The Anonymous geographer of Ravenna places Cerasus 60 stadia east of Coralla, and 90 west of Hieron Oros, and on a river of the same name.
The name, and possibly the population, of the town were translated to Pharnacia in the Hellenistic era.
[3] Its site is tentatively located near Gelida Kale in Asiatic Turkey.
