A superbly bound and unusually clean copy in a contemporary Dutch binding of one of the most decorative works on shells. The beautifully handcoloured engraved plates depict nearly a thousand shells. The last ten plates, which were published after Knorr's death, have a dark brown background in contrast to the illustrated white shells. The extraordinary quality of the plates represent the eighteenth century continuation of the tradition of Dürer, and it is scarcely an exaggeration to say that the beauty of some of Knorr's illustrations exceeds that of their models. Most of them are after drawings by the author, C. Dietsch and J.C. Kleemann. The portrayed shells come from famous Dutch cabinets such as the one of Martin Houttuyn, physician of Amsterdam, who had a very large collection of shells, containing many rare species; the cabinet of W. van der Meulen, a wealthy merchant of Amsterdam; the cabinet of J. Brandt, druggist of Amsterdam. Also from the cabinet of J.P. Breyn, physician of Dresden, as well as the cabinets of Schadeloock, Muller and others. Provenance: Bookplate of Anne Geraldine Tennant.
