Author: Karen Armstrong The city of Jerusalem stands as a religious crossroads unlike any place in history. As such, it possesses a volatile chemistry that--as we are made painfully through news reports and television--explodes on a regular basis. Karen Armstrong, a former Roman Catholic nun who teaches Judaism and is an honorary member of the Association of Muslim Social Services, has compiled a thorough narrative of the city's fascinating 3,000-year history. Though she emphasizes the city's religious turning points, she recounts battles, earthquakes and various other events, such as invasions by the Romans and the Crusaders, just a millennium apart, that nearly wiped out the city. Her comprehensive explanations provide a context to the current strife in Israel.
