Καὶ πάλιν ἐπεὶ ἐν πάσῃ νυκτὶ ἓξ ζῴδια δύνει ἐν ὥραις ιβ′, ⟨καὶ ἐν πάσῃ ἡμέρᾳ ἓξ ζῴδια δύνει ἐν ὥραις ιβ′, φανερὸν ὅτι καὶ ἐν ἡμέρᾳ καὶ ἐν νυκτὶ ιβ′ ζῴδια δύνει ἐν ὥραις ἰσημεριναῖς κδ′, τὸ δὲ ἓν ζῴδιον δύνει ἐν δυσὶν ὥραις ἰσημεριναῖς κατὰ τὸν μέσον τῶν δύσεων χρόνον.⟩ Φανερὸν ⟨δὲ⟩ ἐκ τῶν αὐτῶν ὅτι τὸ ἓν ζῴδιον ἐν δυσὶν ὥραις δύνει καὶ ἐν δυσὶν ὥραις ἀνατέλλει, ὥςτε ἐν ὥραις τέσσαρσιν ἰσημεριναῖς δύνει καὶ ἀνατέλλει. καὶ πάντων τῶν ζῳδίων ὁ συναμφότερος χρόνος τῆς ἀνατολῆς καὶ τῆς δύσεως ἐστὶν ἴσος ⟨χρόνῳ⟩ ὡρῶν ἰσημερινῶν τεσσάρων. Καὶ ὅσα μὲν τῶν ζῳδίων ἐν πλείστῳ χρόνῳ ἀνατέλλει, ἐν ἐλαχίστῳ χρόνῳ δύνει, ὅσα δὲ ἐν ἐλαχίστῳ χρόνῳ ἀναφέρεται, ἐν πλείστῳ χρόνῳ δύνει.
