Passage 8.19.1
εἰσὶ δέ τινες γένους μὲν καὶ οὗτοι τῶν Ἀρκάδων, ὄνομα δέ σφισι Κυναιθαεῖς, οἳ καὶ ἐν Ὀλυμπίᾳ τὸ ἄγαλμα ἀνέθεσαν τοῦ Διός, κεραυνὸν ἐν ἑκατέρᾳ ἔχοντα τῇ χειρί· οὗτοι οἱ Κυναιθαεῖς τεσσαράκοντα ἀπωτέρω Λουσῶν σταδίοις μᾶλλον οἰκοῦσι, καί σφισιν ἐν ἀγορᾷ πεποίηνται μὲν θεῶν βωμοί, πεποίηται δὲ Ἀδριανοῦ βασιλέως εἰκών.
There are others who are also Arkadians by race, and these are called the Kynaithaians; they dedicated at Olympia a statue of Zeus, holding a thunderbolt in each hand. These Kynaithaians dwell about forty stades further than Lousoi; in their agora are altars of the gods, and also a statue of the emperor Hadrian.
