I segreti della techne: Isocrate nella dossografia aristotelica.

Isokrates never wrote a handbook, but as a lifelong teacher he developed for his students a body of rules and exercises, which were known to contemporary witnesses, such as Speusippus and Aristotle, as his 'technics' (technai). Aristotle entered them in his Synagoge Technon, a doxographical survey of rhetorical theories up to his time, and the book was still available to the Neoplatonic Syrianus, who quotes tenets of Isocratean doctrine from this source. These are the first textual fragments of the Synagoge identified so far.
