A revolution momentarily rearranges the density of human conglomerations. Squares like Cairo‘s Tahrir, fairly lively on an average day, can suddenly be filled with millions of people or, if the military blocks them off, be utterly devoid of them. Before 2011, the square between the Cheops and Chephren pyramids teemed with tourists. When we visited in November 2013, it was a gaping void. Tourism has reduced dramatically since the revolution, particularly in Cairo and Luxor. For months, tour guides, horse-drawn carriages and those renting out camels have been waiting in vain for customers.
