Argus

Argus, or Argos, in Greek mythology, (1) the designer of the Argonauts' ship Argo; (2) the old dog who died after recognizing his master, Odysseus, returning in disguise to his home in Ithaca after an absence of 19 years; (3) the monster called Panoptes (the all-seeing) because of the great number of eyes in his head and over his body. He was ordered by Hera to watch Io, who had been transformed into a cow, but Hermes killed him, and by Hera's orders, Argus's eyes were sprinkled as decorations through the tail of the peacock.
