A pocket guide to the art, history and culture of Petra with hundreds of archival and color illustrations, maps, site plans and a section of original documents. It includes a detailed overview of individual buildings and sectors within the desert city. Occupied by the Nabataeans from the 4th-century BC, conquered by the Romans, and overrun by the Crusaders, the city was long lost to the west; only the local people knew of this desert stronghold until its rediscovery by the Swiss explorer Burckhardt in 1812.  (JRD13, $15.95)
