The view of the ‘Tombs of the Mamluks’, a group of 14th-century minarets with Saladin’s citadel rising behind, was a popular subject for early photographers in Egypt, including Flaubert’s companion, Maxime du Camp, who took perhaps the first calotypes of the tombs. It was now unrecognisable. A swath had been cleared in front of al-Suyuti’s squat white dome. At the base of the bulb-capped Sultaniyya minaret, the excavators clawed open dozens of new and old crypts. There was the thud of stone breaking. Piles of rubble dwarfed the labourers. Backing away, I stumbled over half a skull. To the north, the bright orange flowers of the flame trees stood out in the ruins.
