Owing to the prevalent illiteracy among the people in these dark ages, the Church, in its mission of spiritual guidance, relied, as of old, on the preacher’s word. The power of his exhortations was seconded, however, by silently eloquent, impressive teachings surrounding the worshipers, namely, the scenes and figures of religious import, painted upon the walls of the church. That same endeavor to stimulate pious thoughts carried the miniature into liturgical books, into religious manuscripts generally. The writing-room of the monastery was all-sufficient to provide for the pious needs of clergy, rulers, and nobles. Here the patient copyist drew again and again the outlines of the large illuminated initials of his text, until he bethought himself of the labor he might save by imitating the cloth-printer, and cutting wooden relief-blocks of these outlines which he might stamp upon his parchment. An early device this, adopted in the twelfth or thirteenth century, but clearly foreshadowing the development which was soon to follow. Meantime, in that iron age religious enthusiasm had fired the crusaders, the armor-clad Occident had met the Orient, bringing back some of the wisdom of the ancient East into the scholar’s study and the convent cell, and broadening man’s outlook upon the world. We know how Gothic architecture grew up in the North, how in the Gothic church the ample wall space, which had been heretofore the realm of painting, was divided, reduced, suppressed. We know how the curtailed pictorial art sought new spheres of expression, how the panel picture took possession of the altars. Before long this picture, which could be shifted from one position to another, was used independently of altars, for the adornment of suitable wall spaces in the church, until finally it found its way from the church to the home, henceforth to be one of its indispensable adornments. As painting made its way into the lay world, the impersonal, traditional, dogmatic character of sacred subjects faded away. Not that ecclesiastic art had lost its deeply religious sincerity, but the artist saw nature with new eyes; he realized the beautiful world around him, and lovingly painted the plants and flowers at the feet of the Virgin. He removed her throne from the formal diapered background of gold, and placed it in the midst of the actual living world. The figures became more personal and lifelike; worldly subjects, even portraits, or at least efforts in the direction of individual differentiation, came within the artist’s sphere, while as yet the sacred subject remained the one great theme of artistic expression.
