Book excerpt: This biography of the ancient Jewish military leader examines how he mounted a years-long revolt against Rome that changed the course of history. In AD 132, a bloody struggle began between two determined leaders over who would rule Judea. One was the powerful Roman Emperor Hadrian, who some regarded as divine. The other was Shim’on—known today as Bar Kokhba—a Jewish military commander in a district of a minor province, who some believed to be the ‘King Messiah’. In Bar Kokhba, ancient historian Lindsay Powell examines the clash between these two men, and the two ancient cultures they represented. In the ensuing conflict, the Jewish militia resisted the onslaught of the professional Roman army for three-and-a-half years. They established an independent nation with its own administration, headed by Shim’on as its president. The outcome of that David and Goliath contest was of great consequence, both for the people of Judaea and for Judaism itself. Drawing on archaeology, art, coins, inscriptions, militaria, as well as secular and religious documents, Lindsay Powell sheds light on Bar Kokhba’s singular life and legacy. She also describes her personal journey across three continents to establish the facts.
