A page of writing and five separate initials from a book of "Hours," written in Flanders or Holland at the end of the fifteenth century, are here shown, with a border of the same period from another volume. The first book, which is in a private collection, affords an example of the kind of illumination which is styled by the French "grisaille," a word which may be translated "grey-work." In this style, which consists usually in the artist restricting himself to certain colors, or to black, grey, and white only, very few books were ever written. I have already, in the General Sketch, mentioned one which had pictures in imitation of Limoges enamels. A volume apparently illuminated by the same hand as those in our MS. is in the Burgundian Library at Brussels. The figure pictures in both look as if they were not painted by the same artist as the writing and illumination of the letters, and it is probable two or more were employed in the production. There was great activity in all the arts in the Low Countries during the fifteenth century, and the most gorgeous books ever illuminated were written there at that period. At Dortrecht, at Bruges, and other places there were schools of illuminators, and the practice of the art was not confined, as in England, to ecclesiastics and the cloister. The books written were, however, mainly religious; and the same designs were used over and over again. It would, in fact, be easy to identify each guild of miniature painters by their employment of the same set of forms. This eventually led to deterioration, and only the introduction of oil painting, by turning the minds of the artists into a wider channel, saved Flemish art. The masters of the Van Eycks, of Memling, of Matsys, of Van Romerswale were undoubtedly the teachers of illumination in books. The artist in "grisaille" always took especial pains with his draperies. He had so little wherewith to produce his effect that he sometimes almost reached the _chiaro-scuro_ of a later period. Some of the pictures of this school which I have seen look as if they were intended to represent moonlight views. In the present volume the effect of the soberly coloured figure subjects is greatly enhanced by the rich colors of the border, and the brilliantly burnished gilding. The ground on which the letter O is gilded in Plate VI., is quartered into red and blue, and the outer part "counter-changed," as they say in heraldry. A delicate pattern is worked over the colors in body-white. The small leaves are painted with thick coats of Emerald Green.
