Passage 1.4.6
Περγαμηνοῖς δὲ ἔστι μὲν σκῦλα ἀπὸ Γαλατῶν, ἔστι δὲ γραφὴ τὸ ἔργον τὸ πρὸς Γαλάτας ἔχουσα. ἣν δὲ νέμονται οἱ Περγαμηνοί, Καβείρων ἱεράν φασιν εἶναι τὸ ἀρχαῖον· αὐτοὶ δὲ Ἀρκάδες ἐθέλουσιν εἶναι τῶν ὁμοῦ Τηλέφῳ διαβάντων ἐς τὴν Ἀσίαν. πολέμων δὲ τῶν μὲν ἄλλων, εἰ δή τινας ἐπολέμησαν, οὐκ ἐς ἅπαντας κεχώρηκεν ἡ φήμη· τρία δὲ γνωριμώτατα ἐξείργασταί σφισι, τῆς τε Ἀσίας ἀρχὴ τῆς κάτω καὶ ἡ Γαλατῶν ἀπʼ αὐτῆς ἀναχώρησις καὶ τὸ ἐς τοὺς σὺν Ἀγαμέμνονι Τηλέφου τόλμημα, ὅτε Ἕλληνες ἁμαρτόντες Ἰλίου τὸ πεδίον ἐλεηλάτουν τὸ Μήιον ὡς γῆν τὴν Τρῳάδα. ἐπάνειμι δὲ ἐς τὴν ἀρχὴν ὅθεν ἐξέβην τοῦ λόγου.
The Pergamenes possess spoils taken from the Galatians, and also a painting depicting the battle against the Galatians. The territory they now occupy, the Pergamenes claim was originally sacred to the Cabeiri. They themselves wish to be considered Arcadians, descended from those who crossed over to Asia together with Telephus. Regarding the other wars they may have fought, their fame has not survived equally in every case; but three achievements in particular stand out prominently for them: their rule over Lower Asia, the repulse of the Galatians from their lands, and the heroic struggle of Telephus against Agamemnon's forces, at the time when the Greeks, having lost their way to Troy, ravaged by mistake the plain of the Mysians, assuming it was Trojan soil. Now I shall return to the starting point from which I departed from my narrative.
