One man has within the last thirty years accomplished, not for Denmark only, but for Europe, what the whole united labours of earlier archæologists failed to do. About the year 1815, the present Danish Councillor of State, C. J. Thomsen, the son of a merchant of Copenhagen, was appointed Secretary of a Royal Commission for the preservation and collection of national antiquities. It had then been in existence some seven or eight years, and the whole result of its labours was a few miscellaneous articles, unclassified and uncared for, lying in a small room of the University Library. His enthusiasm in the study of the antiquities of his country surmounted all obstacles. He had to contend alike with the theories of the scholar and the prejudices of the unlearned. But he had succeeded to a position of the utmost value to a man of energy and enthusiasm. From the first he had grants (though exceedingly small ones) of public money at his disposal. He soon enlisted the more important element of public sympathy, and nationality of feeling, in his pursuits. His little room became too small for accumulating purchases and donations. A suite of apartments was yielded, at his intercession, in the Royal Palace of Christiansborg; and as the varied collection increased in his hands, he found himself possessed at once of the space and the elements for systematic classification. The Royal Museum of Northern Antiquities of Copenhagen now numbers between three and four thousand specimens of stone weapons and implements, some hundreds of bronze swords, celts, spear-heads, armillæ, torcs, &c., and a collection of native gold and silver relics unequalled in all the museums of Europe. To it we owe the valuable suggestion of the system of classification now universally adopted in the nomenclature of archæological science--the _Stone_, _Bronze_, and _Iron_ periods, which, simple as it may appear, was first suggested by Mr. Thomsen, and is justly esteemed the foundation of Archæology as a science. By means of it the whole materials of antiquarian study at once arrange themselves according to an intelligible chronology of universal acceptance, and adapted in an especial degree to Northern antiquities. This, therefore, is the system on which the following data are arranged, subject only to such modifications as seem naturally to arise from national or local peculiarities.
