It was quite otherwise with the pre-Raphaelites. They did not paint sober visions, but emotions. They therefore introduced into their pictures mysterious allusions and obscure symbols, which have nothing to do with the reproduction of visible reality. I need cite only one example--Holman Hunt’s _Shadow of the Cross_. In this picture Christ is standing in the Oriental attitude of prayer with outstretched arms, and the shadow of his body, falling on the ground, shows the form of a cross. Here we have a most instructive pattern of the processes of mystic thought. Holman Hunt imagines Christ in prayer. Through the association of ideas there awakes in him simultaneously the mental image of Christ’s subsequent death on the cross. He wants, by the instrumentality of painting, to make the association of these ideas visible. And hence he lets the living Christ throw a shadow which assumes the form of a cross, thus foretelling the fate of the Saviour, as if some mysterious, incomprehensible power had so posed his body with respect to the rays of the sun that a wondrous annunciation of his destiny must needs write itself on the floor. The invention is completely absurd. It would have been childish trifling if Christ had drawn his sublime death of sacrifice, whether in jest or in vanity, in anticipation, by his shadow on the ground. Neither would the shadow-picture have had any object, for no contemporary of Christ’s would have understood the significance of the shadowed cross before he had suffered death by crucifixion. In Holman Hunt’s consciousness, however, emotion simultaneously awakened the form of the praying Christ and of the cross, and he unites both presentations anyhow, without regard to their reasonable connection. If an Old Master had had to paint the same idea, namely, the praying Christ filled with the presentiment of his impending death, he would have shown us in the picture a realistic Christ in prayer, and in a corner an equally realistic crucifixion; but he would never have sought to blend both these different scenes into a single one by a shadowy connection. This is the difference between the religious painting of the strong healthy believer and of the emotional degenerate mind. In the course of time the pre-Raphaelites laid aside many of their early extravagances. Millais and Holman Hunt no longer practise the affectation of wilfully bad drawing and of childish babbling in imitation of Giotto’s language. They have only retained, of the leading principles of the school, the careful reproduction of the unessential and the painting of the idea. A benevolent critic, Edward Rod,[93] says of them: ‘They were themselves writers, and their painting is literature.’ This speech is still applicable to the school.
