Passage 1.17.6
Μενεσθεὺς δὲ τῶν μὲν παίδων τῶν Θησέως παρʼ Ἐλεφήνορα ὑπεξελθόντων ἐς Εὔβοιαν εἶχεν οὐδένα λόγον, Θησέα δέ, εἴ ποτε παρὰ Θεσπρωτῶν ἀνακομισθήσεται, δυσανταγώνιστον ἡγούμενος διὰ θεραπείας τὰ τοῦ δήμου καθίστατο, ὡς Θησέα ἀνασωθέντα ὕστερον ἀπωσθῆναι. στέλλεται δὴ Θησεὺς παρὰ Δευκαλίωνα ἐς Κρήτην, ἐξενεχθέντα δὲ αὐτὸν ὑπὸ πνευμάτων ἐς Σκῦρον τὴν νῆσον λαμπρῶς περιεῖπον οἱ Σκύριοι κατὰ γένους δόξαν καὶ ἀξίωμα ὧν ἦν αὐτὸς εἰργασμένος· καί οἱ θάνατον Λυκομήδης διὰ ταῦτα ἐβούλευσεν. ὁ μὲν δὴ Θησέως σηκὸς Ἀθηναίοις ἐγένετο ὕστερον ἢ Μῆδοι Μαραθῶνι ἔσχον, Κίμωνος τοῦ Μιλτιάδου Σκυρίους ποιήσαντος ἀναστάτους---δίκην δὴ τοῦ Θησέως θανάτου---καὶ τὰ ὀστᾶ κομίσαντος ἐς Ἀθήνας·
Now Menestheus paid little heed to the sons of Theseus, as they had departed to Euboea to Elephenor. But fearing that Theseus himself might someday return from the Thesprotians, and judging him an opponent difficult to contest, he worked diligently to win the favor of the people so that, even if Theseus should indeed survive and return, he might still be thrust aside later. Theseus sailed to Deucalion in Crete, but winds drove him off course to the island of Skyros. Though the Skyrians welcomed him magnificently because of his family’s renown and the fame of his own deeds, yet Lycomedes plotted his death on that account. Thus the sanctuary of Theseus at Athens was established later than the Persian occupation of Marathon, after Cimon, the son of Miltiades, had laid waste Skyros—thus avenging the death of Theseus—and had brought his bones home to Athens.
