Passage 5.6.4
μετὰ δὲ τὸν Ἄνιγρον ὁδεύσαντι ἐπὶ μακρότερον διὰ χωρίου τὰ πλείονα ὑποψάμμου καὶ ἔχοντος δένδρα πίτυς ἀγρίας, ὀπίσω ἐς ἀριστερὰ Σκιλλοῦντος ὄψει ἐρείπια. τῶν μὲν δὴ πόλεων ἦν τῶν ἐν τῇ Τριφυλίᾳ καὶ Σκιλλοῦς· ἐπὶ δὲ τοῦ πολέμου τοῦ Πισαίων πρὸς Ἠλείους ἐπίκουροί τε Πισαίων οἱ Σκιλλούντιοι καὶ διάφοροι τοῖς Ἠλείοις ἦσαν ἐκ τοῦ φανεροῦ, καὶ σφᾶς οἱ Ἠλεῖοι τούτων ἕνεκα ἐποίησαν ἀναστάτους.
After crossing the Anigrus, and then traveling onward for some distance through land mostly sandy in nature and covered with wild pine trees, you will see on your left behind you the ruins of Skillous. Skillous was one of the cities of Triphylia. During the war between the Pisatans and the Eleans, the inhabitants of Skillous openly allied themselves with the Pisatans, becoming enemies of Elis; therefore, on account of these events, the Eleans utterly destroyed their city.
