Though introduced early into Germany, the style of the Italian Renaissance made its way but slowly in a country where the ideas of the Middle Ages long held possession of people's minds. It was not till after about 1515, when the spread of books and engravings quickened its general acceptance, that the new movement gained ground there. The German goldsmiths, when once they had cast aside the Gothic style, seized upon Renaissance ornament with such avidity that by the second half of the sixteenth century they had acquired a widespread fame, and would seem by their richness of invention to have completely cast into the shade the Italian jewellers of their own day. From an early period there had been a steady flow of artists leaving Germany to study in the great Italian ateliers. The principal of these, and one who influenced his countrymen more than any, was Albert Dürer, who showed in the engravings produced after his journey to Italy a perfect apprehension of Italian design. As it travelled northward, Renaissance ornament increased in freedom from classic rule, and in the hands of the later draughtsmen and engravers who executed patterns for the goldsmiths, it lost much of its original purity, and assumed a mixed style, composed of strap and ribbon work, cartouches, and intricate complications of architectural members; while the industrious affectation of the jewellers of the day for manipulative difficulties led to the production of ornaments whose effect is sometimes marred by over-elaboration of detail. In addition to other circumstances, we must remember that the greater wealth of the middle classes was a powerful factor in the increasing production of jewellery. The goldsmiths consequently occupied an important position; and that there was a great demand for their services is proved by the fact that patterns for jewellery executed on their behalf by the foremost engravers of the day form no unimportant part of the engraved work produced by these artists.
