Passage 4.35.3
Μοθωναίοις δὲ βασιλεὺς μὲν Τραϊανὸς ἔδωκεν ἐλευθέρους ὄντας ἐν αὐτονομίᾳ πολιτεύεσθαι· τὰ δὲ ἔτι παλαιότερα μόνοις σφίσι Μεσσηνίων τῶν ἐπὶ θαλάσσῃ τοιόνδε ἀτύχημα ἰδίᾳ συνέβη γενέσθαι. τὰ ἐν Ἠπείρῳ τῇ Θεσπρωτίδι ὑπὸ ἀναρχίας ἐφθάρη· Δηιδαμείᾳ γὰρ τῇ Πύρρου παῖδες οὐκ ἐγένοντο, ἀλλὰ ὡς τελευτᾶν ἔμελλεν, ἐπιτρέπει τῷ δήμῳ τὰ πράγματα. θυγάτηρ δὲ ἦν Πύρρου τοῦ Πτολεμαίου τοῦ Ἀλεξάνδρου τοῦ Πύρρου·
The emperor Trajan granted to the people of Mothone, who were already free, the right to live under their own autonomy; but sometime further in the past, this particular misfortune befell them alone among the Messenians dwelling upon the seacoast. The affairs of Thesprotian Epirus had fallen into disorder due to the absence of governance; for Deidameia, daughter of Pyrrhus, had borne no children, and when she was near death, entrusted the government to the people. She was the daughter of Pyrrhus, son of Ptolemy, who was the son of Alexander, and he in turn was son of Pyrrhus.
