1. Some plots are “simple” and some “complex,” as indeed the actions represented by the plots are obviously such.
1. εἰσὶ δὲ τῶν μύθων οἱ μὲν ἁπλοῖ οἱ δὲ πεπλεγμένοι· καὶ γὰρ αἱ πράξεις ὧν μιμήσεις οἱ μῦθοί εἰσιν ὑπάρχουσιν εὐθὺς οὖσαι τοιαῦται.
2. By a simple action I mean one that is single and continuous in the sense of our definition above, wherein the change of fortune occurs without “reversal” or “discovery”; by a complex action I mean one wherein the change coincides with a “discovery” or “reversal” or both.
2. λέγω δὲ ἁπλῆν μὲν πρᾶξιν ἧς γινομένης ὥσπερ ὥρισται συνεχοῦς καὶ μιᾶς ἄνευ περιπετείας ἢ ἀναγνωρισμοῦ ἡ μετάβασις γίνεται, πεπλεγμένην δὲ ἐξ ἧς μετὰ ἀναγνωρισμοῦ ἢ περιπετείας ἢ ἀμφοῖν ἡ μετάβασίς ἐστιν.
4. These should result from the actual structure of the plot in such a way that what has already happened makes the result inevitable or probable; for there is indeed a vast difference between what happens propter hoc and post hoc.
4. ταῦτα 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.
