Meanwhile, here, upon the plain below, another and fairer city was arising--Augustodunum, the Roman capital of Gaul, now known as Autun. It has often been asserted that the location of Bibracte upon Mont Beuvray is merely legendary, and that Autun is the historic site of the great city of the Aedui. But this theory, as we have seen, has been finally exploded by the researches of M. Bulliot. He proves conclusively, not only that Bibracte was situate on the summit of Beuvray, but also that Autun was built upon virgin soil, and not upon the site of a Gallic city, which would inevitably have yielded tangible proof of its existence in Gaulish coins and other remains. The proportion of Gaulish to Roman coins found in Autun, up to the present time, is about one to fifteen hundred.[16] Further evidence is offered by the fact that the city conforms to the requirements mentioned by Vitruvius at the time of its erection--about fifteen to ten years before the Christian era--that, in building a town, the first necessity is to choose a healthy site, elevated, not subject to fogs, of good temperature, not exposed to extremes of heat and cold, away from marshy land, and facing south or west.[17] One of the chief features of Burgundian towns is the excellence of their sites. This feature, due no doubt, to Roman example, is nowhere more noticeable than at Autun, which remains to-day one of the best situate, and among the most interesting, of all the cities of France. * * * * * The first thing to be done, it seems to me, in exploring such a place as Autun, which comprises a mediæval and a modern town within the Enceinte of a Roman city, is to get your bearings, to orient yourself, as the French say. On the previous evening, looking up from our sunset seat on the grass, beside that mysterious pile known as the Temple of Janus, we had seen, far above the city, to the south-east, on the slope of the hills which enthrone Autun, a gaunt, grey stone lifting its head over the village roofs of Couhard. The next morning found us descending the Rue St. Pancras, into the hollow that lies between the village and the town. As we climbed the ascent, the rising sun gave us alluring glimpses of the mysterious stone, seen through the curling mists of an autumn morning; yet, many a time, we turned from it, to watch the light playing upon ancient wall and tower, and gilding the spire of the cathedral of St. Lazare. [Illustration: AUTUN; shewing Cathedral and Mediæval Towers] A bend to the left brought us into Couhard, a straggling group of dishevelled cottages and huts lining the Ruisseau de la Toison, that bubbles merrily along the side of the hill. It is a dilapidated, picturesque, tangled village, given over to ducks and dirt, and to washerwomen, who, like flies in summer, settle upon the running waters of France, to wash their toisons d'or.
