[CHAPTER I.]
The Discovery of Metals—Various Reasons suggested for explaining the Origin of Bronze in the West—The Invention of Bronze—A Foundry during the Bronze Epoch—Permanent and Itinerant Foundries existing during the Bronze Epoch—Did the knowledge of Metals take its rise in Europe owing to the Progress of Civilisation, or was it a Foreign Importation?
The acquisition and employment of metals is one of the greatest facts in our social history. Thenard, the chemist, has asserted that we may judge of the state of civilisation of any nation by the degree of perfection at which it has arrived in the workmanship of iron. Looking at the matter in a more general point of view, we may safely say that if man had never become acquainted with metals he would have remained for ever in his originally savage state.
There can be no doubt that the free use of, or privation from, metals is a question of life and death for any nation. When we take into account the important part that is played by metals in all modern communities, we cannot fail to be convinced that, without metals civilisation would have been impossible. That astonishing scientific and industrial movement which this nineteenth century presents to us in its most remarkable form—the material comfort which existing generations are enjoying—all our mechanical appliances, manufactures of such diverse kinds, books and arts—not one of all these benefits for man, in the absence of metals, could ever have come into existence. Without the help of metal, man would have been condemned to live in great discomfort; but, aided by this irresistible lever, his powers have been increased a hundredfold, and man's empire has been gradually extended over the whole of nature.
In all probability, gold, among all the metals, is the first with which man became acquainted. Gold, in a metallic state, is drifted down by the waters of many a river, and its glittering brightness would naturally point it out to primitive peoples. Savages are like children; they love everything that shines brightly. Gold, therefore, must, in very early days, have found its way into the possession of the primitive inhabitants of our globe.
Gold is still often met with in the Ural mountains; and thence, perhaps, it originally spread all over the north of Europe. The streams and the rivers of some of the central countries of Europe, such as Switzerland, France, and Germany, might also have furnished a small quantity.
After gold, copper must have been the next metal which attracted the attention of men; in the first place, because this metal is sometimes found in a native state, and also because cupriferous ores, and especially copper pyrites, are very widely distributed. Nevertheless, the extraction of copper from the ores is an operation of such a delicate character, that it must have been beyond the reach of the metallurgic appliances at the disposal of men during the early pre-historic period.
The knowledge of tin also dates back to a very high antiquity. Still, although men might become acquainted with tin ores, a long interval must have elapsed before they could have succeeded in extracting the pure metal.
Silver did not become known to men until a much later date; for this metal is very seldom met with in the tumuli of the bronze epoch. The fact is, that silver is seldom found in a pure state, and scarcely ever except in combination with lead ores; lead, however, was not known until after iron.
