Argus Panoptes
He was a son of Zeus and Niobe, daughter of Phoroneus, and is possibly the brother of Pelasgus. Argus married either Evadne, the daughter of Strymon and Neaera, or Peitho the Oceanid, and had by her six sons: Criasus, Ecbasus, Iasus, Peiranthus (or Peiras, Peirasus, Peiren), Epidaurus and Tiryns (said by Pausanias to be the namesake of the city Tiryns). According to Pausanias, yet another son of Argus was the Argive Phorbas (elsewhere his grandson through Criasus). Meanwhile, Cercops speaks of Argus Panoptes as the son of Argus and Ismene.
