The elaborate hinges, clasps, and locks of doors and coffers that were often enriched still further with coats of arms are also of great interest and appear to have been made subjects of lavish decoration before the larger domestic belongings were so treated. Of the decorations of lock-plates the German example of the Imperial Eagle from the Town Hall, Nuremberg (Fig. 183), is interesting as an instance of great simplification of form to suit the material in which it is expressed. Fig. 184 is another but more ornate example of the treatment of pierced and chased metal. [Illustration: FIG. 183.--Lock-plate. German. From the Town Hall, Nuremberg.] [Illustration: FIG. 184.--Decorated Hinge in Pierced and Chiselled Metal. German. Seventeenth Century.] [Illustration: FIG. 185.--Lock-plate. Chiselled Iron. French. Fifteenth Century.] The French lock-plate in chiselled iron (Fig. 185) was in the Spitzer Collection, and is decorated with the crowned Arms of France, and with Navarre, Aragon, Bearn and Bourbon quarterly and with a coat at top repeated on either side, consisting of three pommes de pin, or pine cones. The fleur-de-lis in Gothic tracery on the hasp is also notable. Fig. 186 bears the crowned Arms of France surrounded by the beautiful collar of St. Michael. Below is the well-known monogram which combines the initials of Henry II and of Diana de Poitiers, and her badge of crescents forms a circular device interlaced within the guilloche border, and a further allusion to her goddess namesake occurs in the bows and arrows at the sides. A fellow bolt-plate in the same collection has the Arms of France dimidiating those of Medici and Dauphiny on the shield at top, and in place of the crescent badge below, is a rainbow in clouds and surrounded by laurel; and the monogram, a double K for Queen Katherine, is several times repeated. [Illustration: FIG. 186.--Bolt-plate. French. Sixteenth Century.] [Illustration: FIG. 187.--Panel in Chiselled Iron. Sixteenth Century.] A very beautiful work, also in chiselled iron, is the panel of the armorial insignia of the Emperor Charles V, the Arms with the Columns the latter rising from waves of the sea, being the device that represented the Pillars of Hercules and the motto “plus oultre” (Fig. 187). The arms are encircled with the collar of the Toison d’Or very boldly treated. The work is Spanish of the early sixteenth century, and is notable for its exquisite finish as well as for its general excellence of design and drawing.
