Sir William Woodthorpe Tarn (1869-1957) was a British ancient historian who wrote numerous works on the Hellenistic world. Tarn's Alexander the Great, first published in two volumes during 1948, has become a classic text and its importance for subsequent Alexander studies can hardly be exaggerated. Based on a lifetime's work and elegantly and persuasively written, both volumes evoked immediate admiration - and very soon sharp reaction. Volume I presents a 'compendious' narrative of Alexander's life and achievements; volume II focuses on providing a detailed analysis of sources and discussion relating to key historical cruces. This is a fascinating work that will be of value to anyone with an interest in the writings of Tarn, ancient history and Alexander the Great.
