(Πείρασος), or PEIRAS, the son of Argus, a name belonging to the mythical period of Greek art. Of the statues of Hera, which Pausanias saw in the Heraeum near Mycenae, the most ancient was one made of the wild pear-tree, which Peirasus, the son of Argus, was said to have dedicated at Tiryns, and which the Argives, when they took that city, transferred to the Heraeum (Paus. 2.17.5). The account of Pausanias and the mythographers, however, does not represent Peirasus as the artist of this image, as some modern writers suppose, but as the king who dedicated it. (Comp. Paus. 2.16.1; Schol. ad Eurip. Orest. 920; Apollod. 2.1.2; Euseb. Praep. evan. 3.8; Thiersch, Epochen, 20.)
