(Ἀρίστων) and TELESTAS (Τελεστὰς), brothers, were the sculptors of a colossal statue of Zeus which the Cleitorians dedicated at Olympia from the spoils of many captured cities. The statue with its pedestal was about eighteen Greek feet high. It bore an inscription, which is given by Pausanias, but in a mutilated state. (Paus. 5.23.6.)
