Ambrosia

In the ancient Greek myths, ambrosia, the food or drink of the Greek gods, is often depicted as conferring longevity or immortality upon whoever consumed it. It was brought to the gods in Olympus by doves and served either by Hebe or by Ganymede at the heavenly feast. Ancient art sometimes depicted ambrosia as distributed by the nymph named Ambrosia, a nurse of Dionysus.
