KYDNOS (or Cydnus) was a River-God of Kilikia in Anatolia (modern Turkey).
The River Kydnos had its headwaters in the Tarsos Mountains on the Kilikian border with Syria. It flowed into the Meditteranean near the city of Tarsos. The most important neighbouring rivers were the Lamos to the west and the Orontes of Syria in the south-east.
Nonnus, Dionysiaca 24. 102 ff (trans. Rouse) (Greek epic C5th A.D.) :
"The daughters of Kydnos [i.e. Naiades], the River that loved Zephryos (the West Wind) . . . these his father had given to Bakkhos for victory in the Indian War."
