Vertus forms the southern limit of the Côte d'Avize, and the vineyard slopes subsiding at their base into a broad expanse of fertile fields, and crested as usual with dense forest, rise up behind the picturesque old town, which is mentioned in a letter of the Emperor Louis and a charter of Charles the Bald in the ninth century. It was once strongly fortified, though a dilapidated gateway is all that to-day remains of the ancient ramparts, which failed to secure it in 1380, when the English, under the 'Comte de Bouquingouan,' presumably Buckingham, burnt the whole of the town except the Abbey of St. Martin, and elicited from the native poet, Eustache Deschamps, _dit_ Morel, 'huissier d'armes' to Charles VI. and castellan of Fismes, a lamentation, wherein he fails not to mention the high renown of the local vintage.[394] [Illustration: OLD HOUSES AT VERTUS.] Vertus can still boast a curious old church of the eleventh century, with solid Romanesque towers, elaborate mouldings, and richly ornamented capitals; also a picturesque promenade, shaded with centenarian trees, together with several quaint old houses, including one with a florid Gothic window surrounded by a border of grapes and vine-leaves, and another with a quaintly projecting corner turret, dominated by a conical roof. The Vertus vineyards are mentioned in a charter of the Abbey of Ste. Marie, dated 1151. They were originally planted with vines from Beaune in Burgundy, and in the fourteenth century yielded a red wine held in high repute, of pleasant flavour, and rich in perfume,[395] but which would appear to have been imbued with those purgative properties[396] traceable in other growths of the Champagne. The red wine of Vertus formed the favourite beverage of William III. of England, and was long in high repute. To-day, however, the growers find it more profitable to make white instead of red wine from their crops of black grapes, the former commanding a good price for conversion into _vin mousseux_, from being in the opinion of some manufacturers especially valuable for binding a _cuvée_ together. The Vertus growths rank among the second-class Champagne crus.[397] [Illustration: SILLERY AND ITS VINEYARDS.] II. /The Champagne Vinelands--The Vineyards of the Mountain./
