A Catalogue, Of Impressions In Sulphur: Of Antique And Modern Gems From Which Pastes Are Made And Sold (1775) by James Tassie is a book that provides a comprehensive list of antique and modern gems that were used to create pastes. The book is essentially a catalogue of impressions made in sulphur, which were then used to create molds for gems. The book is divided into sections based on the type of gem, including cameos, intaglios, and seals. Each section provides a detailed description of the gem, including its size, shape, and design. The book also includes illustrations of each gem, which were created using the impressions in sulphur. The illustrations are highly detailed and provide a clear representation of each gem. The book is an important resource for anyone interested in the history of gemstones, as well as for collectors and dealers of antique gems.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
