Passage 7.1.2
χρόνῳ δὲ ὕστερον ἀποθανόντος Ἕλληνος Ξοῦθον οἱ λοιποὶ τοῦ Ἕλληνος παῖδες διώκουσιν ἐκ Θεσσαλίας, ἐπενεγκόντες αἰτίαν ὡς ἰδίᾳ χρήματα ὑφελόμενος ἔχοι τῶν πατρῴων· ὁ δὲ ἐς Ἀθήνας φυγὼν θυγατέρα Ἐρεχθέως ἠξιώθη λαβεῖν καὶ παῖδας Ἀχαιὸν καὶ Ἴωνα ἔσχεν ἐξ αὐτῆς. ἀποθανόντος δὲ Ἐρεχθέως τοῖς παισὶν αὐτοῦ δικαστὴς Ξοῦθος ἐγένετο ὑπὲρ τῆς ἀρχῆς, καὶ---ἔγνω γὰρ τὸν πρεσβύτατον Κέκροπα βασιλέα εἶναι---οἱ λοιποὶ τοῦ Ἐρεχθέως παῖδες ἐξελαύνουσιν ἐκ τῆς χώρας αὐτόν·
Later, after Hellen had died, Xuthus was driven out of Thessaly by the remaining sons of Hellen, who brought the charge against him that he had secretly stolen and kept part of their father's property for himself. Fleeing to Athens, he was deemed worthy to marry a daughter of Erechtheus, and by her he had sons, Achaeus and Ion. Upon Erechtheus' death, Xuthus served as judge among Erechtheus' sons regarding the kingship. Because he awarded the throne to Cecrops, the eldest, the other sons of Erechtheus drove him from the land.
