Institutio Oratoria

also lived about the same period: while Theophrastus, the pupil of Aristotle, produced some careful work on rhetoric. After him we may note that the philosophers, more especially the leaders of the Stoic and Peripatetic schools, surpassed even the rhetoricians in the zeal which they devoted to the subject.

Hermagoras next carved out a path of his own, which numbers have followed: of his rivals Athenaeus seems to have approached him most

But the rhetoricians who attracted the most enthusiastic following were Apollodorus of Pergamus, who was the instructor of Augustus Caesar at Apollonia, and Theodorus of Gadara, who preferred to be called Theodorus of Rhodes: it is said that Tiberius Caesar during his retirement in that island was a constant attendant at his lectures.

These rhetoricians taught different systems, and two schools have arisen known as the Apollodoreans and the Theodoreans, these names being modelled on the fashion of nomenclature in vogue with certain schools of philosophy. The doctrines of Apollodorus are best learned from his pupils, among whom Cains Valgius was the best interpreter of his master's views in Latin, Atticus in Greek. The only text-book by Apollodorus himself seems to be that addressed to Matius, as his letter to Domitius does not acknowledge the other works attributed to him. The writings of Theodorus were more numerous, and there are some still living who have seen his pupil Herinagoras.
