During twelve years of continuous campaigns, Alexander conquered an empire that stretched from the shores of the Adriatic to the edge of modern India. Arrian's history of those conquests, the most reliable and detailed account to emerge from the ancient world, is a work that will fascinate readers interested in classical studies, the history of warfare, and the origins of East-West tensions that still simmer today in Iraq, Iran, and Afghanistan. Drawing on Ptolemy's memoirs and other sources that have not survived antiquity, Arrian's portrait of Alexander is unmatched for its accuracy and immediacy. Having served as a high Roman official with command of an army, Arrian had a unique perspective on Alexander, imbued with a level of understanding that only firsthand military experience can provide. In the richly illustrated and annotated style of the Landmark series, The Campaigns of Alexander, which features an engaging and eloquent new translation by Pamela Mensch, brings together some of the pre-eminent classics scholars at work today to create what is certain to be the definitive edition of this essential work of history.
