acquired the epithet Argeiphontes or “Argus-slayer”. The sacrifice of Argus liberated Io and allowed her to wander the earth, although tormented by a gadfly sent by Hera, until she reached the Ionian Sea, named after her, from where she swam to Egypt and gave birth to a love child of Zeus, according to some versions of the myth. According to Ovid, Argus had a hundred eyes. Hera had Argus' hundred eyes preserved forever in a peacock's tail so as to immortalise her faithful watchman. In another version, Hera transformed the whole of Argus into a peacock. The myth makes the closest connection of Argus, the neatherd, with the bull. According to the mythographer Apollodorus, Argus, "being exceedingly strong ... killed the bull that ravaged Arcadia and clad himself in its hide". Eponyms Argus Panoptes is referenced in the scientific names of at least eight animals, each of which bears a pattern of eye spots: reptiles Cnemaspis argus, Eremias argus, Sibon argus, Sphaerodactylus argus, and the Argus monitor Varanus panoptes; the pheasant Argusianus argus; the fish Cephalopholis argus and the cowry Arestorides argus.
