Adamanthea helped raise Zeus after hiding him from his child-devouring father, Cronus.
Adamanthea, along with the goat-nymph Amalthea, are revered as the foster mothers of Zeus. Reacting to a prophecy from his mother, Gaia, that his own offspring would overthrow his supreme position in the pantheon, Cronus swallowed all of his children immediately after birth. Rhea, Zeus' mother, and Cronus' wife, deceived Cronus by giving him a stone wrapped to look like a baby instead of Zeus, whom she instead gave to Adamanthea to nurse. Since Cronus ruled over the earth, the heavens, and the sea, Adamanthea hid Zeus by dangling him on a rope from a tree, suspended between earth, sea, and sky, and thus invisible to his father.
