Ὅταν οὖν καὶ οἱ ἐνιαυτοὶ ἀκριβῶς ἄγωνται καθ’ ἥλιον καὶ οἱ μῆνες καὶ αἱ ἡμέραι κατὰ σελήνην, τότε νομίζουσιν οἱ Ἕλληνες κατὰ τὰ πάτρια θύειν, τοῦτο δέ ἐστι κατὰ τοὺς αὐτοὺς καιροὺς τοῦ ἐνιαυτοῦ τὰς αὐτὰς θυσίας τοῖς θεοῖς συντελεῖσθαι. Οἱ μὲν γὰρ Αἰγύπτιοι τὴν ἐναντίαν διάληψιν καὶ πρόθεσιν ἐσχήκασι τοῖς Ἕλλησιν. οὔτε γὰρ τοὺς ἐνιαυτοὺς c ἄγουσι καθ’ ἥλιον, οὔτε τοὺς μῆνας καὶ τὰς ἡμέρας κατὰ σελήνην, ἀλλ’ ἰδίᾳ τινὶ ὑποστάσει κεχρημένοι εἰσί. βούλονται γὰρ τὰς θυσίας τοῖς θεοῖς μὴ κατὰ τὸν αὐτὸν καιρὸν τοῦ ἐνιαυτοῦ γίνεσθαι, ἀλλὰ διὰ πασῶν τῶν τοῦ ἐνιαυτοῦ ὡρῶν διελθεῖν καὶ γίνεσθαι τὴν θερινὴν ἑορτὴν καὶ χειμερινὴν καὶ ⟨τὴν⟩ φθινοπωρινὴν καὶ ἐαρινήν. ἄγουσι γὰρ τὸν ἐνιαυτὸν ἡμερῶν τξε′· ιβ′ γὰρ μῆνας ἄγουσι τριακονθημέρους καὶ πέντε ἐπαγομένας· τὸ δὲ δ ον οὐκ ἐπάγουσι διὰ τὴν προειρημένην αἰτίαν, ἵνα αὐτοῖς ἀναποδίζωνται αἱ ἑορταί.
