 It seems that Aristotle was the author not only of the Rhetoric as we know it today, but of several treatises dealing with rhetoric. According to ancient testimonies, Aristotle wrote an early dialogue on rhetoric entitled ‘Grullos’, in which he put forward arguments for why rhetoric cannot be an art (technê); and since this is precisely the position of Plato’s Gorgias (see §4 of  Plato: rhetoric and poetry),  the lost dialogue Grullos has traditionally been regarded as a sign of Aristotle’s (alleged) early Platonism (see Solmsen 1929, 196–208). But the evidence for the position defended in this dialogue is too tenuous to support such strong conclusions: it also could have been a ‘dialectical’ dialogue, simply listing the pros and cons of the thesis that rhetoric is an art (see Lossau 1974). We are in a similar situation concerning another lost work on rhetoric, the so-called ‘Technê Sunagogê’, a collection of previous theories of rhetoric that is also ascribed to Aristotle. Cicero seems to use this collection, or at least a secondary source relying on it, as his main historical source when he gives a short survey of the history of pre-Aristotelian rhetoric in his Brutus 46–48. Finally, Aristotle once mentions a work called ‘Theodecteia’ which has also been supposed to be Aristotelian; but more probably he refers to the rhetorical handbook of his follower Theodectes, who was also a former pupil of Isocrates. From these lost works on rhetoric we only have a meagre collection of scattered fragments (frg. 68–69 R3, 114 R3, 125–141 R3: see Rose 1886).
