In 1911, _Royal Copenhagen Porcelain: Its History and Development from the Eighteenth Century to the Present Day_ was issued by my publisher, who in bringing out this sumptuous monograph fell under the spell of the beauty of Copenhagen art. That volume appealed to connoisseurs and collectors and was welcomed both here, on the Continent, and in America. It has been thought desirable, in view of the limited circulation of that volume, to issue a popular edition, which is here presented in a slightly abridged form with none of the essentials omitted. Many of the illustrations have not found their way into this gallery. But a brave array of pictures is given to convey to the general reader, and to those who have not perused the larger volume, the chief characteristics of Royal Copenhagen porcelain, and indicate reasons why this factory is now regarded as the leading factory in Europe. How many of the great factories of the world can claim two great epochs in their history? But Copenhagen can do this. The first is the Müller period (overglaze decoration), when the factory assumed its well-known mark, in 1775, of the three blue lines indicating the three waterways of Denmark--the Sound and the Great and Little Belts. The second great period, the Modern Renaissance (underglaze decoration), practically commenced in 1885. The porcelain of this factory has long been held in high esteem. Admiral Nelson in 1801, when with the British fleet outside Copenhagen, wrote to Lady Hamilton, "I was in hopes to have got off some Copenhagen china to have sent you"; and later, "As I know you have a valuable collection of china, I send you some of the Copenhagen manufacture." The bowl made at the royal factory in memory of the brave Danes who fell in the battle of Copenhagen is herein illustrated. The _Encyclopædia Britannica_ (11th Edition), 1911 (article on _Ceramics_), awards a high place to the Royal Copenhagen Factory, "the productions of which are not only famous all over the world, but have set a new style in porcelain decoration which is being followed at most of the continental factories." At the present time museums and private collectors in this country and in various parts of the world are acquiring Royal Copenhagen porcelain on account of its artistic character.
