Argus Panoptes
In one tradition Telchis was an early king of Sicyon, son and successor of Europs, thus grandson of the primeval king Aegialeus, and was in his turn succeeded by his own son Apis, to whom was subsequently born Thelxion. In another version Telchis and Thelxion, whose genealogy is not stated, are said to have deposed and killed the Argive Apis, son of Phoroneus and Teledice, who had left no offspring. Apis' death was later avenged on them by Argus Panoptes.
