(Ἄργος).

1. The third king of Argos, was a son of Zeus and Niobe. (Apollod. 2.1.1, &c.) A Scholiast (ad Hom. Il. 1.115) calls him a son of Apis, whom he succeeded in the kingdom of Argos. It is from this Argus that the country afterwards called Argolis and all Peloponnesus derived the name of Argos. (Hyg. Fab. 145; Paus. 2.16.1, 22.6, 34.5.) By Euadne, or according to others, by Peitho, he became the father of Jasus, Peiranthus or Peiras, Epidaurus, Criasus, and Tiryns. (Schol. ad Eurip. Phoen. 1151, 1147; ad Eurip. Orest. 1252, 1248, 930.)
