For nearly two and a half millennia, Alexander the Great has loomed over history as a legendûand an enigma. Wounded repeatedly but always triumphant in battle, he conquered most of the known world, only to die mysteriously at the age of thirty-two. In his day he was revered as a god; in our day he has been reviled as a mass murderer, a tyrant as brutal as Stalin or Hitler. Who was the man behind the mask of power? Why did Alexander embark on an unprecedented program of global domination? What accounted for his astonishing success on the battlefield? In this luminous new biography, the esteemed classical scholar and historian Guy MacLean Rogers sifts through thousands of years of history and myth to uncover the truth about this complex, ambiguous genius.
