Reqem Walk in the Desert.
The first series is from the necropolis Petra in the Jordanian desert. More than 2000 years ago it was the prosperous capital of the Nabataeans and a centre for caravans. It lost importance when the caravans took a short cut and sailed up the Red Sea with the monsoon winds to get to their trade destination at the Mediterranean. - Here the history of Petra-Reqem is used as a metaphor of our time.
