Enchiridion of Epictetus

The Enchiridion or Handbook of Epictetus (Ἐγχειρίδιον Ἐπικτήτου, Enkheirídion Epiktḗtou) is a short manual of Stoic ethical advice compiled by Arrian, a 2nd-century disciple of the Greek philosopher Epictetus. Although the content is mostly derived from the Discourses of Epictetus, it is not a summary of the Discourses but rather a compilation of practical precepts.
