Lycus (river of Bithynia)
Lycus or Lykos was an ancient river of Bithynia. It flowed in the east of Bithynia in a westerly direction, and emptied itself into the Black Sea a little to the south of Heraclea Pontica, which was twenty stadia distant from it. The breadth of the river is stated to have been two plethra, and the plain near its mouth bore the name of Campus Lycaeus.
