The Anabasis of Alexander

All we know of Arrian is derived from the notice of him in the Bibliotheca of Photius, who was Patriarch of Constantinople in the ninth century, and from a few incidental references in his own writings. We learn from Suidas that Dion Cassius wrote a biography of Arrian; but this work is not extant. Flavius Arrianus was born near the end of the first century of the Christian era, at Nicomedia, the capital of Bithynia. He became a pupil of the famous Stoic philosopher Epictetus, and afterwards went to Athens, where he received the surname of the “younger Xenophon,” from the fact that he occupied the same relation to Epictetus as Xenophon did to Socrates.
