wrote many original books. By far the most important of these is the Anabasis of Alexander, or the History of Alexander the Great's Campaigns. This is one of the most authentic and accurate of historical works. Though inspired with admiration for his hero, the author evinces impartiality and freedom from hero-worship. He exhibits great literary acuteness in the choice of his authorities and in sifting evidence. The two chief sources from which he drew his narrative were the histories written by Ptolemy, son of Lagus, and Aristobulus, son of Aristobulus, both of whom were officers in Alexander's army. Other authorities quoted by Arrian himself were:—Eratosthenes, Megasthenes, Nearchus, Aristus, and Asclepiades. He also made use of Alexander's letters, which he mentions five times;[1] only once, however, quoting the exact words of the writer. The last authority which he mentions, is the Royal Diary kept by Eumenes, of Cardia, the private secretary of Philip as well as of Alexander, and by the historian Diodotus, of Erythrae. It is used by Arrian only once,[2] as it is by Plutarch.[3]

This book is written in the Ionic dialect, like the History of Herodotus and the Indica of Ctesias. The latter untrustworthy book Arrian wished to supplant
