Argus Panoptes

Argus Panoptes (or Argos) is a many-eyed giant in Greek mythology. The figure is known for having spawned the saying "the eyes of Argus", as in to be "followed by", "trailed by", "watched by", et cetera the eyes; the saying is used to describe being subject to strict scrutiny in one's actions to an invasive, distressing degree. The monstrous entity has been either directly included or indirectly alluded to in a wide variety of works influenced by Greco-Roman thought over the past several centuries.

Argus Panoptes (Ἄργος Πανόπτης), guardian of the -nymph Io and son of Arestor, was a primordial giant whose epithet, "Panoptes", "all-seeing", led to his being described with multiple, often one hundred, eyes. The epithet Panoptes was applied to the Titan of the Sun, Helios, and was taken up as an epithet by Zeus, Zeus Panoptes. "In a way," Walter Burkert observes, "the power and order of Argos the city are embodied in Argos the neatherd, lord of the herd and lord of the land, whose name itself is the name of the land."

The epithet Panoptes, reflecting his mythic role, set by Hera as a very effective watchman of Io, was described in a fragment of a lost poem Aigimios, attributed to Hesiod:

And set a watcher upon her, great and strong Argus, who with four eyes looks every way. And the goddess stirred in him unwearying strength: sleep never fell upon his eyes; but he kept sure watch always.

In the 5th century and later, Argus' wakeful alertness was explained for an increasingly literal culture as his having so many eyes that only a few of the eyes would sleep at a time: there were always eyes still awake. In the 2nd century AD Pausanias noted at Argos, in the temple of Zeus Larissaios, an archaic image of Zeus with a third eye in the center of his forehead, allegedly Priam's Zeus Herkeios purloined from Troy.
