THE BAROQUE IN ROMAN CATHOLIC COUNTRIES C. I6OO-C. 1760 naissance. Its source is the France of Louis XTV, as will be shown later (see p. 168), He had started in the artillery force of the Prince- Bishop of Wiirzburg. There he had shown a keen interest in mathe- matics and fortification. Michelangelo too, it will be remembered, had worked on the defence engineering, and some of the other leading 16th-century architects in Italy, e.g. Sammicheli, had been distinguished military engineers. The Prince-Bishop singled out young Neumann for architectural work, made him his surveyor of works and sent him to Paris and Vienna to discuss the plans for his new palace at Wiirzburg with his opposite numbers there, the French king's and the Emperor's architects, and to learn from them. Thus his most famous work, the palace at Wiirzburg, is only partly his; but his experience grew, and the Bishop appreciated him more and more. He was made a captain, then a major, then a colonel, but he had no longer any duties of active service and could devote all his time to architecture. He did all the designing and supervising for the Bishop that had to be done, and was soon also asked to design palaces and churches for other clients. Thus churches of the i8th century in Germany may originate from very different milieus: the workshop of the mediaeval craftsman or the drawing-board of the technically skilled courtier. Differences in architectural character may often be explained in this way. Asam churches are naive, Neumann's are of an intellectual complexity equal to Bach's. Spatial effects, however, are as important in the Asams' as in Neumann's work. But the Asams stick to the more ostentatious devices of optical illusion (raising them, it is true, to a high emotional pitch), while Neumann composes his configurations of space scorning easy deceptions. At Rohr near Ratisbon the Asams, instead of a High Altar, placed in the chancel of the church a showpiece, cruder than Bernini's St. Teresa, and twice as melodramatic: the Apostles, life-size figures standing around a life-size Baroque sarcophagus, and the Virgin rising to Heaven supported by angels to be received into a glory of clouds and cherubs high above. Wild gesticulation and dark glowing colour all help to inflame the passions of faith. The chancel at Welfenburg, another church near Ratisbon, is the stage for a more mysterious apparition: a silver St. George on horseback wielding a flame-shaped sword and riding straight towards us out of a back- ground of dazzling light which is let in from concealed windows. The dragon and die princess stand out as dark golden silhouettes 134
