Petra and the Incense Road
1Petra lies in rugged sandstone mountains in what is now southern Jordan, south of the Dead Sea. Deserts stretch to the east and south. Only a few inches of rain fall there in a year, almost all of it in winter, and summers are hot and dry. The main way into Petra is the Siq, a winding canyon about three-quarters of a mile long and in places only about 10 feet wide, with tall cliffs on both sides.
2Far to the south, in southern Arabia, grew the trees whose sap was dried to make frankincense and myrrh. Temples across the Mediterranean world burned these sweet-smelling resins, and buyers paid high prices for them. Camel caravans carried them north for weeks through dry country to ports such as Gaza, on the Mediterranean coast. Along much of the way water was scarce, and caravans depended on people who knew where to find it. The Nabataeans, an Arab people, came to control part of this route, around Petra.
3The trade made the Nabataeans rich, and their wealth drew enemies. About 312 BCE, Antigonus, one of the generals who fought over Alexander the Great's empire after his death, sent soldiers to seize Nabataean goods. According to ancient writers, the soldiers struck while many Nabataean men were away at a market and carried off incense and silver, but the Nabataeans chased them and destroyed most of the force. A second army soon gave up and went home.
4Archaeologists have found that the Nabataeans built dams, cut channels into the rock and dug cisterns to store winter rain and spring water. A channel along the Siq carried water into the city. Over time Petra filled with stone buildings, and grand tombs were carved into its cliffs; many of the most famous were probably made in the first century BCE or the first century CE. Rome took control of the Nabataean kingdom in 106 CE.
