Adamanthea

Since she instead gave the infant Zeus to Adamanthea to nurse in a cave on a mountain in Crete, it is clear that Adamanthea is a doublet of Amalthea.

Since Cronus ruled over the earth, the heavens, and the sea, Adamanthea hid him by dangling him on a rope from a tree so he was suspended between earth, sea, and sky and thus, invisible to his father.
