Delphinus
the rescuing dolphin
Today this word meansA small but sharply drawn summer constellation.
The dolphin that carried the poet Arion on its back after he leapt into the sea, and saved him.
Another version, handed down alongside it, makes it the dolphin that found the fleeing Amphitrite and persuaded her to return to Poseidon.
Either way, it is a story of a dolphin helping a human. In the ancient Mediterranean, killing a dolphin was taboo.
