Passage 8.1.1
Ἀρκάδων δὲ τὰ πρὸς τῆς Ἀργείας Τεγεᾶταί τε ἔχουσι καὶ Μαντινεῖς, νέμονται δὲ οὗτοί τε καὶ τὸ ἄλλο Ἀρκαδικὸν τὸ μεσόγαιον τῆς Πελοποννήσου. Κορίνθιοι γὰρ οἰκοῦσιν ἐπὶ τῷ ἰσθμῷ πρῶτοι· Κορινθίοις δὲ τὰ πρὸς θαλάσσης εἰσὶν Ἐπιδαύριοι γείτονες· τὰ δὲ ἐς Ἐπίδαυρον καὶ Τροιζῆνά τε καὶ Ἑρμιόνα ὁ κόλπος ἐστὶν ὁ Ἀργολικὸς καὶ ὅσα ἐπιθαλάσσια τῆς Ἀργείας· ταύτης δὲ ἔχονται τῆς χώρας Λακεδαιμονίων περίοικοι, τούτοις δὲ ὅμορος ἡ Μεσσηνία· καταβαίνει γὰρ μέχρι θαλάσσης ἐς Μοθώνην καὶ Πύλον καὶ ἐπὶ Κυπαρισσιάς.
The territory of the Arcadians towards Argolis is possessed by the Tegeans and Mantineans, and these, along with the rest of Arcadia, occupy the inland region of the Peloponnese. The Corinthians dwell first on the Isthmus. Their neighbors on the seacoast are the Epidaurians; and the gulf known as the Argolic Gulf extends along Epidaurus, Troezen, Hermione, and all the seacoast parts of Argolis. Bordering this region are the Perioeci of the Lacedaemonians, who in turn neighbor Messenia. For Messenia stretches down to the sea at Methone, Pylos, and Cyparissiae.
