2. Δέον τοίνυν εἰδέναι σε, ὡς ἡ οἰκουμένη πᾶσα πρὸς τὸ μέγεθος τῆς ὅλης γῆς ἀναλογιζομένη τὸ τέταρτον ταύτης εὑρίσκεται. Ἐπειδὴ γὰρ σφαιροειδῆ ταύτην παρελάβομεν εἶναι, καὶ περίμετρον ἔχειν μοιρῶν τξ, τὰς μὲν ρπ΄ κατὰ τὸ φαινόμενον μέρος τῆς γῆς ὑποθώμεθα, τὰς δ᾿ ἑτέρας ρπ τῷ μὴ φαινομένῳ δῶμεν. Τοῦτο δὲ ποιήσωμεν ἐπὶ τοῖς τέσσαρσι τῆς οἰκουμένης μέρεσι, βορείῳ λέγω καὶ νοτίῳ καὶ ἑσπερίῳ καὶ ἑῴῳ.
