§10.1εἰσὶ δὲ τῶν μύθων οἱ μὲν ἁπλοῖ οἱ δὲ πεπλεγμένοι· καὶ γὰρ αἱ πράξεις ὧν μιμήσεις οἱ μῦθοί εἰσιν ὑπάρχουσιν εὐθὺς οὖσαι τοιαῦται.
Of plots, some are simple and others are complex; for the actions indeed of which the plots are imitations are already from the start of this very character.
§10.2λέγω δὲ ἁπλῆν μὲν πρᾶξιν ἧς γινομένης ὥσπερ ὥρισται συνεχοῦς καὶ μιᾶς ἄνευ περιπετείας ἢ ἀναγνωρισμοῦ ἡ μετάβασις γίνεται, §10.3πεπλεγμένην δὲ ἐξ ἧς μετὰ ἀναγνωρισμοῦ ἢ περιπετείας ἢ ἀμφοῖν ἡ μετάβασίς ἐστιν.
I call that action simple which, as it proceeds in a continuous and single course as defined, has its transition occur without reversal or recognition; and complex, that action from which the transition occurs with recognition or reversal or both.
§10.4ταῦτα δὲ δεῖ γίνεσθαι ἐξ αὐτῆς τῆς συστάσεως τοῦ μύθου, ὥστε ἐκ τῶν προγεγενημένων συμβαίνειν ἢ ἐξ ἀνάγκης ἢ κατὰ τὸ εἰκὸς γίγνεσθαι ταῦτα· διαφέρει γὰρ πολὺ τὸ γίγνεσθαι τάδε διὰ τάδε ἢ μετὰ τάδε.
These things must arise from the very constitution of the plot, so that they result from what has gone before, occurring either of necessity or according to probability; for there is a great difference between something happening "because of this" or "after this."
