[31] Cunynghame (H. H.), _European enamels_, p. 69. From the beginning of the thirteenth century a change takes place with the appearance of the Gothic style. Forms become slighter and more elegant, and exhibit greater delicacy and detail in their workmanship. Hitherto goldsmith's work, however beautiful from the cumulative effect of precious stones and enamels, was little more than conventional, nay, almost barbaric, in its representations of the human figure; but the revival in the art of figure sculpture led to a considerable use being made of the human figure executed in full relief. Just as in the Romanesque period, so during the time when Gothic art reigned supreme, architecture left its impress on every work of art; and jewellery and other goldsmith's work, as well as ivories, seals, and even shoes, were ornamented with the designs of Gothic architecture and with pierced open-work patterns, like the window tracery of the great cathedrals--termed "Paul's windows" by the masses. Improved skill in design and workmanship became incompatible with the retention of the older and coarser enamel-work, and without relinquishing a medium which by the brilliancy of its colouring was eminently suited to the works of the goldsmith, the thirteenth-century craftsman obtained the desired result by the use of translucent enamel upon metal, usually silver, chased and modelled in low relief. The beauty of this _basse-taille_ enamel, producing, as it were, transparent pictures, enabled the artist frequently to dispense with coloured gems, and retain only pearls, whose delicate hues harmonised better with his work. Occasionally, however, pearls, precious stones, and translucent enamels were employed together with brilliant effect.
