Giovanni Karcher was a Flemish tapestryGLOSSARYAs historical climatologists have not shown that Renaissance Italian winters and springs were warmer than they are now, it is puzzling that Italy did not fabricate tapestries to decorate and draught-proof the stony rooms of its palaces until 1545, when Cosimo I set up a manufactory in Florence. To hardiness or stinginess (tapestry was by far the most expensive form of wall decoration) we owe the existence of such secular frescoed decorative schemes as the labours of the months in the castle at Trent (c. 1407), the Arthurian scenes of Pisanello and the courtly ones of Mantegna in the Ducal Palace of Mantua, the delicious calendar fantasies of Cossa and others in the Palazzo Schifanoia in Ferrara - and, doubtless, many others that await liberation from whitewash or later panelling. These are all in situations where northern patrons would have used tapestries. These were imported, chiefly from Flanders, into Italy. The influence of their hunting and ceremonial scenes in particular registered on Italian 'gothic' painting or illumination and stained glass, and in literature. But the Italians did not make them. The most famous of all 'Italian' tapestries, those for the Sistine Chapel designed by Raphael, were made in Brussels from the full-scale coloured patterns, or cartoons, now in the Victoria and Albert Museum, London. Nor is it clear whether imported tapestries were used habitually or simply to add grandeur to special occasions. Even when Cosimo's manufactory was in being, and working from designs by court artists of the calibre of Bronzino, Salviati and Allori, his own headquarters, the Palace of the Signoria (now the Palazzo Vecchio), was being decorated with frescoes. The subject is underexplored. weaver active in Italy. He organized with his brother Nicolas Karcher a large workshop for Ercole d'Este II, Duke of Ferrara and Modena. This workshop produced important series of tapestries, such as the famous Scipio tapestries after drawings by Giulio Romano.
