KYTHEROS was a River-God of Elis in the Peloponnesos, southern Greece.
The Kytheros stream was a tributory of the Alpheios. It flowed down from Mount Pholoe, past the town of Herakleia, to merge with the Alpheios, a short distance downstream from Olympia.
Strabo, Geography 8. 3. 32 (trans. Jones) (Greek geographer C1st B.C. to C1st A.D.) :
"Herakleia, which is also one of the eight cities [of the region of Triphylia in Elis]; it is about forty stadia distant from Olympia and is situated on the Kytheros River, where is the temple of the Ioniades Nymphai, who have been believed to cure diseases with their waters."
Pausanias, Description of Greece 6. 22. 7 (trans. Jones) (Greek travelogue C2nd A.D.) :
"Distant from Olympia about fifty stades is Herakleia, a village of the Eleans, and beside it is a river Kytheros. A spring flows into the river, and there is a sanctuary of Nymphai near the spring . . . their common surname is Ionides."
