The gold altar tray and chalice (Fig. 94) were found near Gourdon, in the Department of the Haute-Saône. The altar tray has a cross in the centre, and lozenge and trefoil ornaments of Cloisonné garnet-coloured enamels. Greek coins of the sixth century were found with it. The Byzantine reliquary (Fig. 95) is another example of Cloisonné work. At Cologne, in the cathedral, is the shrine of the Magi that contains the skulls of the “Three Kings.” This is a magnificent reliquary made by the order of the Archbishop Philip von Heinsberg in two storeys, both of which have a series of arcades with figures in each. It is also an example of enamelled work in which the Cloisonné and Champlevé processes may be seen. The first authentic or dated specimens of Champlevé enamels belong to the twelfth century, though some specimens are likely of an earlier date. Some crosses and other works of the dates 1041-1054 show a mixture of the two embedded varieties of enamels. It is probable that the Rhenish Provinces of Germany were the first places where Champlevé enamels were extensively made; but almost simultaneously in the twelfth century there arose an active centre of work in this method in Limoges, the future great seat of the enamel industry. [Illustration: Fig. 95—Byzantine Reliquary, Cloisonné Enamel; Tenth Century.] The German variety may be distinguished from the French by the greater number of colours employed: there is a difficulty in deciding which of the two is the earlier. The Abbé Suger, when building the Abbey of St. Denis, brought enamellers from Loraine, near the Rhine, to make an enamelled cross, which they completed between 1143 and 1147. A portable altar, and a cruciform reliquary with a dome, in the treasury at Hanover, are early examples of the German school. One of these portable altars in enamel, of the German school, thirteenth century, is shown at Fig. 98. The earliest Champlevé enamel of the Limoges school is that of the monument to Geoffrey Plantagenet, who died in 1151. It is now in the Museum of Le Mans (Fig. 97).
