διὸ δὴ καὶ τὰ μεγέθη τῶν ἡμερῶν καὶ τῶν νυκτῶν ἴσα ἐστὶν ἐν Διδύμοις καὶ Καρκίνῳ. καὶ γὰρ ἐν τοῖς ὡρολογίοις τὸ ἄκρον τῆς τοῦ γνώμονος σκιᾶς τὰς αὐτὰς γράφει γραμμὰς ἐν τοῖς προειρημένοις ζῳδίοις. Ὁ δὲ αὐτὸς λόγος καὶ ἐπὶ τῶν χειμερινῶν τροπῶν.| οὐδὲ γὰρ ἐπ’ ἐκείνων ὑποληπτέον ἐν ὅλῳ τῷ Αἰγόκερῳ μεγίστας νύκτας γίνεσθαι, ἀλλ’ ἕν τι σημεῖόν ἐστι λόγῳ θεωρητόν, ὃ κοινόν ἐστιν Αἰγόκερῳ καὶ Τοξότῃ. τὸ δὲ ὅλον ζῴδιον τὸ τοῦ Αἰγόκερω καὶ τὸ τοῦ Τοξότου τὴν αὐτὴν ἀπόστασιν ἔχει ἀπὸ τοῦ χειμερινοῦ τροπικοῦ σημείου καὶ ὑπὸ τῶν αὐτῶν παραλλήλων ἐμπεριλαμβάνεται κύκλων· ἔστι γὰρ ἀλλήλοις κατὰ συζυγίαν. ὅθεν καὶ τὰ μεγέθη τῶν ἡμερῶν καὶ τῶν νυκτῶν ἴσα ἐστὶν ἐν Τοξότῃ καὶ Αἰγόκερῳ. Καθόλου δὲ ὅσα τῶν ζῳδίων κατὰ συζυγίαν ἀλλήλοις ὑπάρχει, ταῦτα τὰ ζῴδια ἴσας ἡμέρας καὶ νύκτας περιέχει. ἔσονται οὖν ἴσαι ἡμέραι ἐν Διδύμοις καὶ Καρκίνῳ, Ταύρῳ καὶ Λέοντι, Κριῷ καὶ Παρθένῳ, Ἰχθύσι καὶ Ζυγῷ, Υδροχόῳ καὶ Σκορπίῳ, Τοξότῃ καὶ Αἰγόκερῳ.
