οἱ μὲν οὖν ἀρχαῖοι τοὺς μῆνας τριακονθημέρους ἦγον, τοὺς δὲ ἐμβολίμους παρ’ ἐνιαυτόν. ταχέως δ’ ἐπὶ τοῦ φαινομένου ἐλεγχομένης τῆς ἀληθείας διὰ τὸ τὰς ἡμέρας καὶ τοὺς μῆνας μὴ συμφωνεῖν τῇ Ε σελήνῃ, τοὺς δὲ ἐνιαυτοὺς μὴ στοιχεῖν τῷ ἡλίῳ, [ὅθεν] ἐζήτουν περίοδον, ἥτις κατὰ μὲν τοὺς ἐνιαυτοὺς τῷ ἡλίῳ συμφωνήσει, κατὰ δὲ τοὺς μῆνας καὶ τὰς ἡμέρας τῇ σελήνῃ, περιέχει δὲ [ὁ τῆς περιόδου χρόνος] ὅλους μῆνας καὶ ὅλας ἡμέρας καὶ ὅλους ἐνιαυτούς.
