The food, sometimes the ointment or perfume, of the Greek and Roman gods:
In ancient Greek mythology, ambrosia (Greek: ἀμβροσία) is sometimes the food or drink of the Greek gods, often depicted as conferring immortality upon whoever consumed it. It was brought to the gods in Olympus by doves, so it may have been thought of in the Homeric tradition as a kind of divine exhalation of the Earth.
Ambrosia is sometimes depicted in ancient art as distributed by a nymph labeled with that name. In the myth of Lycurgus, an opponent to the wine god Dionysus, violence committed against Ambrosia turns her into a grapevine.
Tantalus was banished to the underworld for stealing ambrosia from Zeus’s table and for offering his son, boiled and cooked, as a peace offering.
