Arrian of Nicomedia
Lucius Flavius Arrianus, known as Arrian, was born around 86 AD in Nicomedia in the province of Bithynia (in present-day northwestern Turkey) and died around 160 AD. He ranks among the most important scholars and writers of the Roman Imperial Period — as a historian, military strategist, and above all as the faithful preserver of the Stoic teachings of his master Epictetus.
Student of Epictetus
As a young man, Arrian traveled to Nicopolis in Epirus, where he attended the lectures of the freed slave and philosopher Epictetus. This encounter would shape his intellectual life. Epictetus taught orally and left no written works of his own. Arrian recognized the risk of losing this wisdom and began carefully transcribing his teacher's lectures. The result was the Diatribai (Discourses, Gr. Διατριβαί) — originally eight books, four of which have survived. They render Epictetus's teaching sessions in vivid, direct language and convey the core principles of Stoic ethics: the distinction between what is up to us (eph' hēmin) and what is not, and the cultivation of inner freedom independent of external circumstances.
From this material Arrian also compiled the celebrated Enchiridion (Ἐγχειρίδιον, "handbook") — a concise, accessible collection of Epictetus's most essential teachings. The Enchiridion became one of the most influential texts in Stoic philosophy and continues to resonate to this day.
Political and Military Career
Arrian was not only a philosopher and writer, but also a man of practical life — fully in the Stoic spirit. He served Emperor Hadrian loyally, became a Roman citizen, and held high offices, including that of Governor of Cappadocia (c. 131–137 AD). In this capacity he proved himself militarily by repelling a threatened Alan invasion.
Historical Works
As a historian, Arrian consciously modeled himself on Xenophon and composed the Anabasis Alexandri, which is regarded as the most reliable ancient source on the campaigns of Alexander the Great. He also wrote works on tactics, hunting (Kynegetikos), and the coast of the Black Sea (Periplus Ponti Euxini).
Significance for Stoicism
Arrian's contribution to the history of philosophy can scarcely be overstated: without his meticulous work of transcription, Epictetus's teachings would have been lost entirely. He combined in a unique way Stoic conviction, political engagement, and literary care — embodying in himself the Stoic ideal of the active, reason-guided human being.
