For that one who proposes to himself to terrify or charm an audience should have plenty of conception to effect such a purpose, and should display to the spectators many-handed, many-headed, or fire-breathing monsters, or men enfolded in the coils of serpents, or that he should seem to increase their stature, or enlarge their natural proportions to a ridiculous extent, or that he should describe men metamorphosed into fountains and trees and birds, a kind of narrative which is not without its attraction for such as take pleasure in things of that sort;—all this, I say, is the clearest of demonstrations that it is possible to arrive at higher knowledge also by means of this inventive faculty.

τὸ γὰρ προθέμενον κατάπληξιν τοῖς ὁρῶσιν ἢ θυμηδίαν τινὰ μηχανήσασθαι τῆς πρὸς τὸ σπουδαζόμενον ἐπινοίας μὴ ἀπορῆσαι, ἀλλ' ἢ πολύχειράς τινας ἢ πολυκεφάλους ἢ πῦρ πνέοντας ἢ δρακόντων ὁλκοῖς συνεσπειραμένους εἰδοποιῆσαι ἢ πρὸς τὸ μεῖζον ἐξᾶραι τὴν συμμετρίαν ἢ διακολοβῶσαι πρὸς τὸ γελοῖον τὰ μέτρα τῆς φύσεως ἢ πηγὰς τοὺς ἀνθρώπους καὶ δένδρα καὶ ὄρνεα γενέσθαι διὰ μεταβολῆς διηγήσασθαι, δι' ὧν ἔστι ψυχαγωγίαν τινὰ τοὺς διὰ τῶν τοιούτων ἡδομένους εὑρεῖν, ἐναργεστάτην ἀπόδειξιν εἶναί φημι τοῦ καὶ τὰ κρείττω τῶν μαθημάτων δύνασθαι ἂν διὰ τῆς εὑρετικῆς δυνάμεως κατανοῆσαι.
