Delphinus, “The Dolphin” earned his place in the night sky by helping out the Greek god of the sea, Poseidon. The deity was in love with Amphitrite, a Nereid, but she was not interested. After many rebuffed attempts he decided to try a new approach. He sent out many messengers with his proposal, and it was the dolphin that convinced Amphitrite to marry the god. For that, Poseidon placed him amongst the stars.
