This lovely little constellation is easily envisaged as the dolphin it is meant to represent. Apparently, it is the dolphin that came to the rescue of the famous Greek poet Arion, who was returning by ship from a competition in which he had won a large sum of money. The avaricious sailors robbed him of the prize and cast him overboard, hoping to hide their crime. But Zeus sent a dolphin to rescue him, and then destroyed the ship with a thunderbolt. Arion was saved and the dolphin thereafter was placed in the sky.
