hundred-eyed giant of Greek mythology, late 14c., from Latin, from Greek Argos, literally "the bright one," from argos "shining, bright" (from PIE root *arg- "to shine; white"). His epithet was Panoptes "all-eyes." After his death, Hera transferred his eyes to the peacock's tail. The name also is used in the figurative sense of "very vigilant person."
