SATNOEIS was a River-God of the Troad, in Mysia, Anatolia (modern Turkey).
The River Satnioeis had its headwaters near the peak of Mount Ida. It flowed west, issuing into the Aegean Sea between the towns of Khryse and Hamaxitos in the South-Westernmost corner of the Troad. Neighbouring rivers were the Skamandros to the north, and Kaikos to the south-east.
Homer, Iliad 14. 440 ff (trans. Lattimore) (Greek epic C8th B.C.) :
"Satnios [a Trojan killed by Aias in the Trojan War], Enops' son, whom the perfect Nymphe Neis had borne once to Enops, as he tended his herds by Satnioeis River."
- Homer, The Iliad - Greek Epic C8th B.C.
