English: Nomadic people left tens of thousands of inscribed rocks, like this one, across Jordan desserts, written in Safaitic (in the north) and Thamudic (in the south) inscription; old Arabian dialects. Safaitic inscription with an image of a Bactrian camel carved on this desert rock. The detailed drawing indicates that the scribe has seen this type of Asian camel, probably along the trade route with China. First century BCE to fourth century CE. From modern-day al-Mafraq, Jordan Hashemite Kingdom. On display at the Jordan Museum, Amman, Jordan.
