Input (English): He once conspired with Hera and Athena to put Zeus in chains; later, he killed the giant Polybotes with an island. Some stories claim that he was raised by the Telchines or hidden in a flock of sheep by Arne at the request of Rhea instead of suffering the fate of most of his siblings. He sent a monster to attack Troy after Laomedon failed to reward him for helping Apollo build walls, and later sent another monster to devour Laocoon. His horse lost to Athenas olive tree in the contest for Athens, his children include Polyphemus and Triton, and his wife is Amphitrite. For 10 points, identify this brother of Hades and trident-wielder, the Greek god of horses and the sea.
