In 1904 H.G. Wells wrote about the Food of the Gods, which transformed regular animals and people into gargantuan proportions. The title was apt, because like us mortals, deities must also feast in order to survive.
Magical Goat Food
Perhaps the most famous divine nourishment would be the ambrosia consumed by the Greek gods on Mount Olympus. Before they discovered this magical foodstuff, gods had to inhale vapors from their dead enemies, akin to taking in the soul of the vanquished.
As the god Zeus grew from a baby to a full-grown thunderbolt-wielding god, he was nursed by a goat (or possibly a nymph) named Amalthea. Baby Zeus, like most infants, grabbed anything near him. While feeding, he broke off one of Amalthea’s horns. This was later transformed into a Cornucopia (or Horn of Plenty).
The Horn of Plenty would create a limitless supply of ambrosia for the gods (along with any type of food for mortals). White doves would whisk this precious food up to Mount Olympus each day.
Nectar was also used interchangeably with ambrosia, though it was said to taste like honey and be carried by a swift eagle.
Ichor and Immortality
The gods and goddesses gained immortality by gobbling up ambrosia and nectar. Immortality has its downside. Their blood transformed to ichor, a divine life force.
If the gods missed too many meals, their immortality would fade away. The great Demeter, goddess of the hearth, went for days without eating in her search for Persephone and nearly perished with the effort.
Mortals and Ambrosia
One story has Achilles gaining his famous invulnerability by being anointed with ambrosia, which burnt away his mortal skin. His mother, Thetis, would have covered his whole body in the stuff, but Peleus, her husband, thought she was trying to harm little Achilles and stopped her, leaving his famous ankle still mortal.
The gods used ambrosia to cure diseases, heal scars and beautify the human body. If applied to a freshly killed hero, the ambrosia would preserve the body forever. When Patroclus died in the Trojan war, his body was anointed with Ambrosia to keep it in a perfect state.
Some believed that if mortals consumed ambrosia (or nectar), they too would become immortal. King Tantalus attempted to seal some of the mythical provisions only to fail and become immortal in another way (punished with eternal hunger in Tartarus).
There might even have been a whole garden with immortality-bearing food. In the far west, where the sun sets, lay the Garden of Hesperides. Three nymphs, called the “Daughters of the Evening” tended the garden which held a special apple tree. One of Hercules’s tasks was to pluck an apple from this tree.
In the play Hippolytus, Euripides mentions a place where “streams flow with ambrosia by Zeus’s bed of love and holy Gaia”. This could possibly be the resting place of the fable Cornucoplia.
That’s a pretty good journey for those doves each day.
