There is a small group of enamelled glass of very uncertain origin which claims attention here. We are concerned with certain little ewers, either of colourless or more often of deep cobalt-blue glass; they are generally mounted in metal, but the handle is always of glass. There are several examples of these ewers in the British Museum, many of which bear dates ranging from 1577 to 1618. The cobalt-blue glass has, by Dr. Brinckmann, been traced back to the glass-houses of Neudeck Platten, on the Saxon-Bohemian frontier. In the treatment, however, of the enamels on these little jugs, we are reminded of some of the work executed by the Altarists in France. The enamelling is of a somewhat more pleasing character than that which we find on the big beakers; white, yellow, green, and red are applied without shading. A favourite subject is a stag-hunt or the coursing of a hare, and at the side is often found a graceful lily of the valley[199] (Plate XL. 2). [Illustration: _PLATE XL_ ENAMELLED BEAKER GERMAN, ABOUT 1600 ENAMELLED JUG WITH PEWTER LID GERMAN, END OF SIXTEENTH CENTURY] To return to our broad cylindrical glasses—the huge _humpen_ and the smaller _kanne_, both of which indeed sometimes take the form of a barrel or a truncated cone—it is usual, on the basis of the decoration, to divide these beakers into the following classes:— 1. The _Reichs-adler Humpen_. On these, the double-headed eagle, displayed, with imperial crown, occupies nearly the whole surface of the glass. A big crucifix covers the breast of the bird, though this is replaced in some examples by the ball of empire. The arms of the seven electors and of the forty-eight members of the _Heilige Römische Reich_ are arranged in a definite order along the outstretched wing feathers[200](Plate XXXIX.). 2. The _Kur-fürsten Humpen_. Here, on the upper zone, the emperor on horseback rides in front of the three spiritual electors—the four lay princes follow below. In other cases the kaiser sits on his throne, with the electors on either side.[201] 3. The Fichtelgebirge glasses, on which a mountain landscape is rudely indicated. None of these glasses can be attributed to an earlier date than the second half of the seventeenth century. A good example in the British Museum shows the Ochsenkopf, one of the highest peaks of the district, as well as the four rivers that issue from its slopes. A padlock hanging by a gold chain over the mountain points to the treasures therein contained: as an often-repeated inscription says:—_An Eisen, Erz und Holz, thut mann viel von ihm ziehen_. Many of these beakers, and perhaps others of a similar character, may be referred to the glass-houses of Bischofsgrün, which are situated at the foot of the Ochsenkopf.
