About the year 1536 the great painter Hans Holbein, who had come to England several years previously, entered into the service of Henry VIII, and it was between that date and his death in 1543 that he executed those masterpieces of design for jewellery which will ever stand as a landmark in the history of the subject. There is no evidence to show that Holbein himself worked in the precious metals. But brought up under similar influences as had moulded the great Italian artists of the Renaissance, Ghiberti, Pollaiuolo, Verrocchio, Francia, and Ghirlandaio, who combined the arts of painting, architecture, and sculpture with the jeweller's craft, he had been well grounded in the limitations of his materials, and knew how far the draughtsman could display his skill in this direction. The most important of Holbein's designs for jewellery are preserved in the British Museum, to which they were bequeathed by Sir Hans Sloane in 1753. The collection, originally mounted in a quarto volume, termed Holbein's London Sketch-book, is now remounted and systematically arranged. The designs, comprising 179 separate items, are for the most part drawn with a pen with black ink, and then some slight touches of brown put in for the shadows. Several of the designs have the ground blackened, the ornaments being left in white. Some of the jewels, entirely coloured and often touched up with gold, are designed for enamelling in high relief; some are perhaps designed for execution in niello, though it is not improbable that these were intended to be ornamented with black champlevé enamel. The most attractive are the patterns for jewels enriched with precious stones and enamels, the majority of which were for neck pendants intended to hang from a chain, ribbon, or silken cord, itself sometimes shown in the drawing (Pl. XXVI).
