The entire edifice, the tower and that portion which has disappeared, formed originally the residence of the governor of the place, the personal representative of the counts who themselves, in default of a special residence in their capital, were forced to lodge therein on their seemingly brief visits. The names of the counts of Tonnerre and Auxerre appear frequently in the historical chronicles of their time, but references to their doings lead one to think that they chiefly idled their time away at Paris. That this great tower made a part of some sort of a fortified dwelling there is no doubt, but that it was ever a part of a seigneurial chateau is not so certain. With respect to the part Auxerre played in the military science of the middle ages it is interesting to recall that the drum, or _tambour_, is claimed as of local origin, or at least that it was here first known in France, in the fourteenth century. No precise date is given and one is inclined to think that its use with the army of Edward III at Calais on the 3rd August, 1347, was really its first appearance across the Channel after all. Above Auxerre the Yonne divides, or rather takes to itself the Armançon and the Seruin to swell its bulk as it flows down through the Auxerrois. Above lies the Avallonnais, where another race of seigneurs contribute an altogether different series of episodes from that of their neighbours. It remains a patent fact, however, that the cities and towns of the valley of the Yonne give one ample proof of the close alliance in manners and customs of all mid-France of mediæval times. The inhabitants of this region are not a race apart, but are traditionally a blend of the "natural" Champenois and the "frank and loyal" Burgundian,--"strictly keeping to their promises, and with a notable probity in business affairs," says a proud local historian. Here in this delightful river valley were bred and nourished the celebrated painter, Jean-Cousin; the illustrious Vauban, the builder of fortresses; the enigmatical Chevaliere d'Eon; the artist Soufflot, architect of the Pantheon; Regnault de Saint-Jean d'Angely, Minister of Napoleon; Bourrienne, his secretary and afterwards Minister of State under the Bourbons. Following the Yonne still upwards towards its source one comes ultimately to Clamecy. Between Auxerre and Clamecy the riverside is strewn thickly with the remains of many an ancient feudal fortress or later chateaux. At Mailly-le-Chateau are the very scanty fragments of a former edifice built by the Comtes d'Auxerre in the fifteenth century, and at Chatel-Censoir is another of the same class. At Coulanges-sur-Yonne is the débris, a tower merely, of what must one day have been a really splendid edifice, though even locally one can get no specific information concerning its history.
