His drawings (as catalogued by Lippmann) include the following: (1) _In the Kunsthalle, Bremen_. Three sketches for pendent whistles, where the sound-producing part is formed of a ball with a hole in it, into which the air is carried by a pipe. In two cases the ball is held in the mouth of a lion, and in the third in the beak of a cock. The animals stand each on a curved pipe, and have a ring above for suspension (L. 124). (2) _In the British Museum_. Two sketches for ring-shaped pendants--apparently whistles (Pl. XXVI, 1). In both cases is air blown from a mouthpiece half-way round the ring into a ball held in an animal's mouth (L. 252). (3) _In the possession of Herr von Feder, Karlsruhe_. Four designs for brooches and clasps, richly ornamented (L. 433-435, and 437). Two of these sketches (L. 433 and 437) and several others (the whereabouts of the originals of which is not known) were etched by Wenzel Hollar in the seventeenth century, and are enumerated in Parthey's catalogue of Hollar's works. The etchings after the two known originals are numbered 2565 and 2561. The other jewels etched by Hollar from Dürer's designs are the following: (1) A pendant in the form of St. George and the Dragon within a laurel wreath, with a ring above and below (P. 165). (2) A girdle-end formed of two dolphins with a chain attached (P. 2559). (3) A buckle and buckle-plate--the buckle formed of two dolphins, the plate ornamented with two cornucopiæ (P. 2560). (4) A round scent-case or pomander (P. 2567). In addition are miscellaneous designs for ornaments, erroneously considered to be patterns for embroidery (P. 2562-3-4 and 2566). A charming representation of a pendent jewel is seen in Dürer's woodcut of the Emperor Maximilian's Triumphal Arch suspended from the Imperial Crown held by the figure of Genius. [Illustration: _PLATE XXVI_ DESIGNS FOR JEWELLERY BY DÜRER AND HOLBEIN] Following Dürer there appeared a number of goldsmiths who, with the spread of the new style over Europe, were prepared to perform the task of remodelling personal ornaments in accordance with the taste of the day. The most ingenious of them, together with some artists of distinction, engraved with great fertility of imagination, for those who were not capable of design, patterns for goldsmith's work and jewellery. A large demand was made on the productive faculties of these engravers, who included among their ranks not only the best artists, termed from the usual small size of their productions "the little masters," but many other designers of goldsmith's ornament; and from their works, multiplied by means of engraving, the numerous craftsmen who worked in gold, enamel, and precious stones, drew their subjects and ideas.
