(Πολυβώτης), a giant, who in the contest between the gods and giants was pursued by Poseidon across the sea as far as the island of Cos. There Poseidon tore away a part of the island, which was afterwards called Nisyrion, and throwing it upon the giant buried him under it. (Apollod. 1.6.2; Paus. 1.2.4 ; Strab. x. p.489.)
