Grisaille painting originated evidently from the suggestions of carved stone-work in cathedral-decoration. The figures of saints occupying niches, which were familiar to the visitants of churches, were the first models that led to the painting of miniatures with the figures in grey tints. It must have been, for a true artist, delightful to triumph over the difficulty of achieving the effects of relief and of modelling with the aid of a single pigment only. To be the master of such an art, and to handle the monochrome in such a way as to run with perfect touch through a gamut of gradations in tone, would surely have been more gratifying than to win success by the splendour of full illumination. The artist did not, however, entirely abstain {76}from the use of gold; he allowed it to shine on the crowns of kings and around the heads of his saints; and colour was used sparingly in the backgrounds. These backgrounds in the pictures of earlier date were ornamental diapered surfaces, but after the first decade or two of the fifteenth century, landscape backgrounds made their appearance. It was, however, some time before the miniaturist succeeded in realising effects of distance, and thus producing true pictures as distinguished from ornamental historiation. The Italians were the first to gain a tolerable knowledge of perspective, but the Flemings were not much behind them. It was not, however, till late in the fifteenth century that anything like a faithful expression of perspective is found in the miniatures of MSS. In the latter part of the fifteenth century, pure grisaille was extended into camaieu; that is, the monochrome might be any other colour than grey, so long as it was used in the same manner. This, however, was usually confined to parts of miniatures, and not inconsistent with a lavish use of gold for the lights, and masses of different colour in other portions of the same picture. The quantity of gold that gave magnificence to the work of the miniaturist in Flanders and France in the last quarter of the fifteenth century became excessive. It was a relief to the eye when this blaze of gold receded before the outcome of late Flemish art. Scarcely any school produced work comparable for delicacy and truth to the miniatures painted in prayerbooks at Bruges and Ghent between 1490 and 1520. _Illuminated Borders in the Fifteenth Century_
