The German taste also showed itself in the character and distribution of the ornament. While this was apt to be spread freely over the façades and was used profusely in the decoration of the windows and doors, it was lavished especially on the gables and dormer gables, so that they are the distinctive feature of the design. To some extent the details of Italian ornament were introduced, but more generally the German carver followed his own taste for bold and deeply cut designs, showing a preference for rusticated masonry, including rusticated pilasters, and drawing on his fancy for grotesques, caryatids and the half-length figures, terminating in a pedestal, known as _gaines_. And the wood carver vied with the sculptor, especially in the interior decoration of ceilings and wall panelling, while the exteriors as well as the interiors afforded scope for the fancy of the painter. The ornamental tendency increased until the purpose seemed to be to cover every available space with decoration; while as the latter grew less and less organic, it became less original. The carver ceased to invent his designs and was satisfied to copy them with tedious repetitions from the pattern books which, compiled apparently in the Netherlands--one of them by Cornelius de Vriendt--circulated through Germany and, as we shall see, found their way to England. They comprised a heterogeneous assortment of motives, for title pages and frontispieces of books as well as for doorheads and other architectural details, and introduced a variety of designs in bands and straps, borrowed from the work of locksmiths and leather-workers. The degradation reached its climax in the Rococo ornament of the early eighteenth century, especially in the Zwinger Palace, Dresden, “the most terrible Rococo work ever conceived, if we except some of the Churrigueresque work in Spain.” In the neighbourhood of the Hartz Mountains, where forests abounded, timber was used with handsome effect in the design of the structure; beams, doors and window frames, corbels, and so forth being richly carved and often coloured. In the alluvial plain of the North, bounded roughly by a line drawn east and west through Berlin, the absence of stone and the abundance of clay encouraged the use of brick both for the structure and its decoration, and developed a skill in the handling of this material that could scarcely be surpassed. Elsewhere stone was plentiful and the main walls were constructed either of masonry or rubble covered with stucco.
