One November afternoo|i in the heart of a Third World city a (farmer began the difficult exercise of leading his horse through a halfcircle. It was difficult because the cart drawn by the horse required a sizable turning radius, because the farmer made the turn while responding to a traffic policeman's choleric gestures, and because no man or horse can be complacent when conducting such a maneuver on the pavement of Sharia Tahrir against Onrushing waves of automobiles. Like many other Egyptian place names this one has political significance. Sharia Tahrir means Liberation Street—which would be an equally ironic designation for another street on another continent in another part of the Third World.
