|  Argus was a hundred-eyed
monster of Greek mythology and guardian of
Hera, the Queen of Gods and the jealous wife of Zeus.
 Hera dispatched
Argus to stand watch over the nymph Io a rival for
 Zeus's affection
(the cow in the background is Io's transformation
 in an unsuccessful
attempt to escape Hera). Zeus ordered Hermes
 to rescue
Io. Hermes hypnotized Argus with his flute and beheaded
 him. To commemorate
Argus's loyalty, the sad Hera adorned the
 peacock's
tail with his eyes.
