Caravaggio picks up the Herodotus. He turns a page, comes over a dune to discover the Gilf Kebir, Uweinat, Gebel Kissu. When Almásy speaks he stays alongside him reordering the events. Only desire makes the story errant, flickering like a compass needle. And this is the world of nomads in any case, an apocryphal story. A mind travelling east and west in the disguise of sandstorm.
