Zeus and Amalthea
The baby Zeus, hidden by his mother, the Titan Rhea, from his offspring-eating father, the Titan Kronos, is reared by the nanny goat Amalthea. In his divine-baby-strength, Zeus accidentally breaks off one of her horns, which becomes the cornucopia, the horn of never-ending nourishment.
