This god put Delphinus in
This god put Delphinus in the stars after the latter helped him court his wife. He and Apollo were forced to build the walls of Troy for King Laodemon after attempting to overthrow Zeus. In another story, this god fathered Despoena and Arion when he seduced Demeter in the form of a stallion, and his wife transformed Scylla into a barking monster after Scylla had an affair with this figure. He lost a contest to Athena when she gave Cecrops an olive branch, thus giving her patronage of Athens. Out of wedlock, he was the father of the Cyclops Polyphemus, and with his wife Amphitrite, he fathered Triton. For 10 points, name this trident-wielding Greek god of the sea.
