Poseidon

Poseidon (Greek: Ποσειδῶν) was the god of the sea, and, as "Earth-Shaker,"[1] of the earthquakes in Greek mythology.[2] The name of the sea-god Nethuns in Etruscan was adopted in Latin for Neptune in Roman mythology: both were sea gods analogous to Poseidon. Linear B tablets show that Poseidon was venerated at Pylos and Thebes in pre-Olympian Bronze Age Greece, but he was integrated into the Olympian gods as the brother of Zeus and Hades.[2] Poseidon has many children. There is a Homeric hymn to Poseidon, who was the protector of many Hellenic cities, although he lost the contest for Athens to Athena. "Wikipedia"
