Ἄργος Πανόπτης was inspired by the Greek myth of Argus Panoptes (Ἄργος Πανόπτης), guardian of the heifer-nymph Io and son of Arestor and probably Mycene (in other version son of Gaia), was a primordial giant whose epithet Panoptes, "all-seeing", led to his being described with multiple, often one hundred, eyes.Argus was Hera's servant. His great service to the Olympian pantheon was to slay the chthonic serpent-legged monster Echidna as she slept in her cave.
