It was the Roman month of September, seven hundred and four years after Romulus-so tradition ran-founded the little village by the Tiber which was to become "Mother of Nations," "Centre of the World," "Imperial Rome." To state the time according to modern standards it was July, fifty years before the beginning of the Christian Era. The fierce Italian sun was pouring down over the tilled fields and stretches of woodland and grazing country that made up the landscape, and the atmosphere was almost aglow with the heat. The dust lay thick on the pavement of the highway, and rose in dense, stifling clouds, as a mule, laden with farm produce and driven by a burly countryman, trudged reluctantly along.
