The completest copies of this painting that are now perhaps extant, are to be found in a well-known set of engravings in copper, by Matthew Merian, the elder, the master of Hollar. There are great doubts as to their first appearance in 1621, as mentioned by Fuessli and Heinecken, but editions are known to exist with the respective dates of 1649, 1696, 1698, 1725, 1744, 1756, and 1789. Some of these are in German, and the rest are accompanied with a French translation by P. Viene. They are all particularly described by Peignot.[62] Merian states in his preface that he had copied the paintings several years before, and given his plates to other persons to be published, adding that he had since redeemed and retouched them. He says this Dance was repaired in 1568 by Hans Hugo Klauber, a citizen of Basle, a fact also recorded on the cut of the painter himself, his wife, Barbara Hallerin, and his son, Hans Birich, by the before-mentioned artist, G. S., and that it contained the portraits of Pope Felix V., the Emperor Sigismund, and Albert, King of the Romans, all of whom assisted at the Council of Basle in the middle of the 15th century, when the painting was probably executed. A greatly altered and modernised edition of Merian's work was published in 1788, 8vo. with the following title, "La Danse des Morts pour servir de miroir à la nature humaine, avec le costume dessiné à la moderne, et des vers à chaques figures. Au Locle, chez S. Girardet libraire." This is on an engraved frontispiece, copied from that in Merian. The letter-press is extracted from the French translation of Merian, and the plates, which are neatly etched, agree as to general design with his; but the dresses of many of the characters are rather ludicrously modernised. Some moral pieces are added to this edition, and particularly an old and popular treatise, composed in 1593, intitled "L'Art de bien vivre et de bien mourir." A Dance of Death is recorded with the following title "Todtentantz durch alle Stande der Menschen," Leipsig, durch David de Necker, formschneider. 1572, 4to.[63] Whether this be a copy of the Basle or the Berne painting, must be decided on inspection, or it may possibly be a later edition of the copy of the wood-cuts of Lyons, that will be mentioned hereafter. In the little Basle, on the opposite side of the Rhine, there was a nunnery called Klingenthal, erected towards the end of the 13th century. In an old cloister, belonging to it there are the remains of a Dance of Death painted on its walls, and said to have been much ruder in execution than that in the Dominican cemetery at Basle. On this painting there was the date 1312. In the year 1766 one Emanuel Ruchel, a baker by trade, but an enthusiastic admirer of the fine arts, made a copy in water colours of all that remained of this ancient painting, and which is preserved in the public library at Basle.[64]
