PARTHENIOS was a River-God of Paphlagonia in Anatolia (modern Turkey).
The most important neighbouring rivers were the Halys in the east, and Nymphaios to the west.
Hesiod, Theogony 337 ff (trans. Evelyn-White) (Greek epic C8th or 7th B.C.) :
"Tethys bore to Okeanos the swirling Potamoi (Rivers) . . . Parthenios, Euenos and Ardeskos, and Skamandros, who is holy [in a list of rivers]."
Homerica, Fragment of Unknown Position 17 (trans. Evelyn-White) (Greek epic B.C.) :
"[The river Parthenios] flowing as softly as a dainty maiden goes."
Quintus Smyrnaeus, Fall of Troy 6. 464 ff (trans. Way) (Greek epic C4th A.D.) :
"Agamestor's son Kleitos [an ally of the Trojans], a bright-haired Nymphe had given him birth beside Parthenios [i.e. the Paphlagonian river], whose quiet stream fleets smooth as oil through green lands, till it pours its shining ripples to the Euxine sea."
