Passage 8.1.3
τούτων τῶν κατειλεγμένων καθηκόντων ἐπὶ θάλασσαν Ἀρκάδες τὸ ἐντὸς οἰκοῦσιν ἀποκλειόμενοι θαλάσσης πανταχόθεν· ὅθεν σφᾶς καὶ Ὅμηρος ἀφικέσθαι φησὶν ἐς Τροίαν παρʼ Ἀγαμέμνονος πλοῖα εἰληφότας καὶ οὐχὶ ναυσὶν οἰκείαις.
Of these enumerated peoples who dwell upon the sea, the Arcadians alone inhabit an inland region, completely cut off from the sea on every side. On this account even Homer says that they came to Troy on ships provided by Agamemnon, and not on vessels of their own.
