The makers of the sixteenth and seventeenth centuries endeavoured to vary as much as possible both the figure of the machine and the material in which it was placed. Not only square, oval, octagonal, and cruciform watches occur, but some in such fanciful shapes as death's-heads, books, shells, acorns, tulips, pears, etc; while rock crystal (to render the works visible) and other stones were often converted into cases. Oval watches, known as "Nuremberg eggs", are usually reckoned among the earliest, but this title was not given to watches till some time after their invention, and as a matter of fact, according to Dr. Rée (_Nürnberg_, p. 172), all egg-watches that have been preserved belong to the seventeenth century. In Hollar's set of plates of the Four Seasons, dated 1641, the lady representing Summer has on her left side depending from her girdle an object of this shape, apparently a watch. The most important pendent ornament to the girdle, from the present point of view, is the pomander, the early history of which has already been alluded to. Throughout the sixteenth, and until about the middle of the century following, the pomander formed an almost invariable adjunct to the girdle, and was occasionally, in the case of men, hung to the long and heavy chains worn at that period round the neck.[171] [171] I will have my pomander of most sweet smell, Also my chains of gold to hang about my necke. _Book of Robin Conscience_ (_circa_ 1600). Most of the pendants still termed pomanders were, as has been already noted, in reality cases for scents or different cosmetics; but from their fruit-like shape, though often innocent of the original pomander ball, they have retained the title, but solely, it would seem, in our own language[172] (Pl. XXXI, 7). [172] The only modern French word for the pomander is _cassolette_. In German and Italian there is a tendency to revive the old titles _Bisamapfel_ and _Oldano_. LATER AND MODERN JEWELLERY CHAPTER XXX SEVENTEENTH-CENTURY JEWELLERY (GENERAL) Through the whole jewellery of the late Renaissance there runs a gradual and profound change of taste. Slowly and by imperceptible stages the earlier style, with its minute enamelled figures in high relief, gives place to a desire for sparkling diamonds, and a pleasure in the glitter of faceted stones. In the sixteenth century, diamonds, rubies, and other stones played a comparatively insignificant part in jewellery, and were prized mainly for their decorative value, but during the course of the seventeenth century a more prominent rôle was gradually conceded to precious stones. Used singly at first, in table-cut form, to give a centre of interest or a note of colour, they came finally to be arranged in juxtaposition and long rows. A complete change was brought about in the whole character of jewellery by the prominence thus given to the precious stone--a position it has retained ever since.
