All this led to much greater individuality among artists than had ever existed before: it came to be understood that a painter could, and had a right to, paint a picture as he wished, and was not governed by any priestly law. Religious subjects were still painted more frequently than others, and the decoration of religious edifices was the chief employment of the artists; but they worked with more independence of thought and spirit. The painters studied more from nature, and though the change was very slow, it is still true that a certain softness of effect, an easy flow of drapery, and a new grace of pose did appear, and about A.D. 1350 a new idea of the uses and aims of painting influenced artists everywhere. [Illustration: FIG. 24.--BIRTH OF THE VIRGIN. _From the Grandes Heures of the Duc de Berri._] About that time they attempted to represent distances, and to create different planes in their works; to reproduce such things as they represented far more exactly than they had done before, and to put them in just relations to surrounding places and objects; in a word, they seemed to awake to an appreciation of the true office of painting and to its infinite possibilities. During this Gothic period some of the most exquisite manuscripts were made in France and Germany, and they are now the choicest treasures of their kind in various European collections. Fig. 24, of the birth of the Virgin Mary, is from one of the most splendid books of the time which was painted for the Duke de Berry and called the Great Book of the Hours. The wealth of ornament in the border is a characteristic of the French miniatures of the time. The Germans used a simpler style, as you will see by Fig. 25, of the Annunciation. The influence of the Gothic order of architecture upon glass-painting was very pronounced. Under this order the windows became much more important than they had been, and it was not unusual to see a series of windows painted in such pictures as illustrated the whole teaching of the doctrines of the church. It was at this time that the custom arose of donating memorial windows to religious edifices. Sometimes they were the gift of a person or a family, and the portraits of the donors were painted in the lower part of the window, and usually in a kneeling posture; at other times windows were given by guilds, and it is very odd to see craftsmen of various sorts at work in a cathedral window: such pictures exist at Chartres, Bourges, Amiens, and other places. [Illustration: FIG. 25.--THE ANNUNCIATION. _From the Mariale of Archbishop Arnestus of Prague._] About A.D. 1300 it began to be the custom to represent architectural effects upon colored windows. Our cut is from a window at Konigsfelden, and will show exactly what I mean (Fig. 26).
