While looking in the sky at night, you try to point out the different constellation you see. Most people know the major constellations, but many do not know about the constellation Delphinus. There are many scientific and literary explanations for the constellation Delphinus. There are two known myths about delphinus. The first is about Arion. Arion was a known poet and musician. He was born on the island of Lesbos. He was known for playing the lyre. This made him famous during the seventh century B.C. He was sailing his way back to Greece after he was touring in southern Italy. During his sail, two sailors planned to steal all the money Arion had made and to kill him. As Arion sang one final song, a group of dolphins swam along the boat. As Arion saw this, he jumped off the boat. For the remainder of the trip, the dolphin transported Arion back to Greece. Arion himself had the sailors condemned to death for trying to steal his money. In the myth, the dolphin is placed next to the lyre and the lyre signifies Arion’s lyre. The dolphin was placed in the sky by Apollo. In the second myth, the dolphin represents the messenger of Poseidon. Amphitrite resisted the Sea God’s advanced and hid among her sisters. Poseidon commanded his messengers to go and find Amphrite and bring her back to the Sea God, among a dolphin. The dolphin found Amphrite and returd ger to the Sea God.
