"If ever a dead city held romance it is Petra...Hewn out of ruddy rock in the midst of a mountain wilderness, sumptuous in ornament and savage in environs, poised in wildness like a great carved opal glowing in a desert, this lost caravan city staggers the most experienced traveller". So wrote Rose Macaulay in her "Pleasure of Ruins" (1953), echoing the sentiments of generations of travellers before and since. Reached through a narrow, winding crevasse betweem looming cliffs in south Jordan, Petra served as the capital city of the Nabatean Arabs from the 3rd century BCE to 106 CE (when it was occupied by the Roman emperor Trajan). In this book, Maria Giulia Amdasi Guzzo and Eugenia Equini Schneider provide an accessible overview of the history and culture of the Nabateans, including their language, religion, politics and economy, as well as a detailed guide to the city of Petra and its art and architecture. A major stop on the spice trade route, Petra attracted wealth and culture from across the Arabic and classical worlds and was abundantly furnished with more than 800 monuments. Perhaps the most well known of these is the Khazneh el-Faroun, or Treasury, a royal tomb more than 130 feet high with a magnificent Hellenistic facade carved from the salmon pink sandstone of the surrounding cliffs. But no less impressive were Petra's advanced achievements in hydraulic engineering, including elaborate water conservation systems and dams. For anyone who has felt the lure and wonder of ancient cities and civilizations in exotic locations, "Petra" should be a valuable resource.
