The Enchiridion, or Manual, of Epictetus; George Long translation

"Among Epictetus' pupils, who came from all parts of the Empire, was a certain Flavius Arrian, later consul under Hadrian and the historian of Alexander. Arrian took careful notes of the lectures and teaching of Epictetus and published them in the eight books of the Discourses, of which the first four have survived. Arrian says in his preface that the Discourses are 'in the very language Epictetus used, so far as possible', and preserve 'the directness of his speech'. Arrian also compiled out of his lecture notes a compendium of the main tenets of Epictetus, the Encheiridion, or Manual" - Great Books of the Western World, Vol. 12.
