extraordinary number of works of art, which originated in this facility and mastery over technical matters, we cannot fail to be astonished and admit that the artistic sense for sculpture is a distinctive impulse and instinct of spirit, which can only, that is, in so overwhelming a degree, appear in one period and one people. In the whole of the Prussian State, for example, at the present time we can easily reckon up the number of bronze statues, the single bronze door of a church we find in Gnesen, and, with the exception of the standing figures of Blücher at Berlin and Breslau, and Luther at Wittenburg, we have merely a few more in Königsberg and Düsseldorf[193]. The very various tone and the infinite adaptability to form and fusibility of this material, which may accommodate itself to every kind of representation, gives to sculpture the pass into every conceivable variety of production, and makes its sensitive material suitable for a host of conceits, prettinesses, utensils, ornaments, and innocent trifles of all kinds. Marble, on the other hand, is limited in its suitability for the depicting of objects and their size; it is, for instance, possible to execute bas-reliefs in it of a certain size on urns and vases. It is, however, unsuitable for smaller objects. In the case of bronze, however, which is not merely cast into specific forms, but can also be beaten into shape and informed by the engraver's tools, there is hardly any type or size of representation which it does not command. We may here, by way of more definite example, instance the case of coinage minting. In this art, too, we find that the ancients executed masterworks of beauty, albeit in the technical aspect of the mere mintage[194] they stand as yet far behind our present elaboration of all that is mechanical in the design. The coins in fact were not really minted, but beaten but of pieces of metal closely resembling a globular form. This department of the art attained its culmination in the time of Alexander. The coins of the Roman Empire have already deteriorated. In our own time Napoleon endeavoured to revive the beauty of antique work in his medals and coinage, and they are of great excellence. In other states, however, the mere worth of the metal and accurate weight is mainly important in the mintage of coin.
