Potamos

The Potamoi (Greek: Ποταμοί, "rivers") are the gods of rivers and streams. The river gods were the sons of the great earth-encircling river Oceanus and his wife Tethys and the brothers of the Oceanids.[1] They were also the fathers of the Naiads. The river gods were depicted in one of three forms: a man-headed bull, a bull-headed man with the body of a serpent-like fish from the waist down, or as an arm resting upon an amphora jug pouring water.

Notable river gods include:
 * Achelous, the god of the Achelous River, the largest river in Greece, who gave his daughter in marriage to Alcmaeon,[2] and was defeated by Heracles in a wrestling contest for the right to marry Deianira.[3]
 * Alpheus, who fell in love with the nymph Arethusa, pursuing her to Syracuse, where she was transformed into a spring by Artemis.[4]
 * Inachus, the first king of Argos and progenitor of Argive line through his son grandson Argus.
 * Nilus, Egyptian river god and the father of numerous daughters that mingled with the descendants of Inachus, forming a dynasty of kings in Egypt, Libya, Arabia and Ethiopia.
 * Peneus, river god of Thessaly flowing from the foot of Pindus. He was the father of Daphne and Stilbe, love interests of the god Apollo.
 * Scamander, who fought on the side of the Trojans during the Trojan War, and, offended when Achilles polluted his waters with the a large number of Trojan corpses, overflowed his banks nearly drowning Achilles.
