A nymph in Greek mythology, Adamanthea helped raise the infant Zeus to hide him from his father, Cronus. Her name comes from the Greek word ἀδάμας (adamas), meaning "untameable" and θεά, the Greek word for goddess.
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.
