Passage 4.1.1
Μεσσηνίοις δὲ πρὸς τὴν σφετέραν τὴν ἀπονεμηθεῖσαν ὑπὸ τοῦ βασιλέως ἐς τὸ Λακωνικὸν ὅροι κατὰ τὴν Γερηνίαν εἰσὶν ἐφʼ ἡμῶν ἡ ὀνομαζομένη Χοίριος νάπη. ταύτην τὴν χώραν ἔρημον οὖσαν οὕτω σχεῖν τοὺς πρώτους λέγουσιν οἰκήτορας· ἀποθανόντος Λέλεγος, ὃς ἐβασίλευεν ἐν τῇ νῦν Λακωνικῇ, τότε δὲ ἀπʼ ἐκείνου Λελεγίᾳ καλουμένῃ, Μύλης μὲν πρεσβύτερος ὢν τῶν παίδων ἔσχε τὴν ἀρχήν, Πολυκάων δὲ νεώτερός τε ἦν ἡλικίᾳ καὶ διʼ αὐτὸ ἰδιώτης, ἐς ὃ Μεσσήνην τὴν Τριόπα τοῦ Φόρβαντος ἔλαβε γυναῖκα ἐξ Ἄργους.
For the Messenians, the boundaries of their allotted territory by the king toward Laconia in our time lie around Gerenia, in the place called the ravine of Choirius. It is said regarding this region, then uninhabited, that the earliest settlers obtained it in the following way. After the death of Lelex, who had ruled over the land which is now known as Laconia but at that time was called Lelegia, Myles, being the elder of his sons, inherited the rule. Polycaon, younger in age, was thus left as a private man until he took as his wife Messene, the daughter of Triopas, who was the son of Phorbas, from Argos.
