Arrian was a pupil of Epictetus around 108 AD, and, according to his own account, he was moved to publish his notes of Epictetus' lectures, which are known as "Discourses of Epictetus", by their unauthorized dissemination. According to George Long, Arrian noted from Epictetus' lectures for his private use and some time later made of these, the "Discourses". Photius states that Arrian produced two books the "Dissertations" and the "Discourses". The Discourses are also known as "Diatribai" and are apparently a verbatim recording of Epictetus' lectures.
