Triton
Greek immortal merman and son of Poseidon. In charge of calming storms at sea.
Triton had the head and upper body of a man, and the tail of a dolphin. His name is probably a variation of his moon-goddess mother's, Aphitrite. Therefore, the new moon of good fortune and luck was associated with him. Triton calmed the waves by blowing on his conch shell, which he also did in the Roman myth, on Neptune's command, during the great flood sent by Zeus. Dolphins are associated with calm seas, when they are most likely to be seen. Like many other gods, Triton could also turn sour what he had turned to good, and vice-versa. Triton rescued ships and people in perilous situations. However, he also sunk ships and drowned people who challenged the gods. He even dragged Euphemus’ ship away after he thankfully sacrificed a sheep to Triton for giving him directions and an island on the Mediterranean for his descendants. Consistent with most mythology, the extent of gods’ mercy was limited to what mood they were in.
