Camel Caravan Reliefs. 100 – 50 BC. In front of you is a monumental relief, about a third larger than life, which depicts and actual caravan in procession. It consists of a group of camels and drivers entering Petra. About ten meters further up, there is a similar carving of a caravan leaving Petra, but this is more eroded. These carvings symbolize the endless procession of people and goods leaving and entering Petra, the economy of which was based on caravan trade. The first camel in the procession has a high hump, indicating that it is a caravan carrying goods. Close inspection of the upper group reveals that the lead driver, whose figure is preserved from the waist down, is clad in a loosely pleated cloth garment of wool. He holds a stick in his bent left arm with which to guide the animals. Text from notice on site.
