Pausanias Description of Greece 1.4.6

[6] They [= the Pergamenes] have spoils-of-war [captured] from the Gauls, and a painting [ graphē] that portrays their deed [ ergon] against them. The land they dwell in was, they say, in ancient times sacred [ hierā] to the Kabeiroi, and they claim that they are themselves Arcadians, being descended from those who crossed into Asia [Minor] with Telephos. Of the wars that they have waged no story [ phēmē] has been made public to the world-at-large, except that they have accomplished three most notable achievements: the subjection of the coastal region of Asia [Minor], the expulsion of the Gauls from there, and the exploit of Telephos against the followers of Agamemnon, at a time when the Greeks [ Hellēnes], after failing to reach Troy, were plundering the plain called Mēion, thinking it Trojan territory. Now I will return from my digression.
