Rhesus
(
Ρῆσος).
1.
A river-god in Bithynia, one of the sons of Oceanus and Tethys.
2.
Son of king Eïoneus in Thrace. He marched to the assistance of the Trojans in
their war with the Greeks. An oracle had declared that Troy would never be taken if the
snow-white horses of Rhesus should once drink the water of the Xanthus and feed upon the
grass of the Trojan plain. But as soon as Rhesus had reached the Trojan territory, and had
pitched his tents late at night, Odysseus and Diomedes penetrated into his camp, slew
Rhesus himself, and carried off his horses. The story is the subject of a play ascribed to
Euripides, but regarded by many as not genuine.
