17. Zeus Turned His Mistress Into a Cow to Hide Her From His Wife
A homeless Io finally gave in to Zeus. To conceal her from his jealous wife and shield her from Hera’s vengeance, the chief god turned Io into a white heifer. It did not work. Hera knew her husband and brother all too well. She began to get suspicious when she noticed just how much time he was spending at a pasture, in which a magnificent white cow grazed. So she asked Zeus to give her the heifer as a present.
Zeus could not think up a good excuse to refuse Hera’s request, so he grudgingly gave his love to his wife as a gift. Hera then assigned Argus Panoptes, a giant with a hundred eyes, to tether the white cow to an olive tree, and keep a constant watch on her. Zeus, driven to distraction by his lust for Io, was unable to bear the separation. So he sent the messenger god Hermes, disguised as a shepherd, to lull Argus to sleep.
