The Sistine Madonna, the only picture of Raphael's painted on canvas, is usually considered to be the greatest religious painting that ever was executed and one of the most wonderful realizations of vivid poetic imagination that the world possesses. Everything in it is full of sublime suggestion. The majestic attitude of the Madonna posed upon the clouds, her face of perfect beauty, her far-away gaze of rapt veneration {13} and absorption in her motherhood, but motherhood of the Divine, proclaim her a vision from Heaven. No more wonderful conception of the human mother of the Divinity has ever been reached and yet critics and artists are a unit in proclaiming that the Virgin Mother is surpassed in wondrous realization of profound imagination by the Divine Child Whom she holds so tenderly in her arms. He looks out into the world from those arms with solemn sacred eyes that somehow give the idea of His profound interest in all that He sees and of an all-embracing vision. Then there is the rugged, bearded Pope Sixtus gazing upward with rapt devotion and the graceful, beautiful Saint Barbara adequately representative of the modest virgins who all over the world, for all the time since the coming of Christ, modestly cast their eyes down before the Virgin Mother and her child. Below are the two exquisite boy angels, whose charming childish attitudes of rapture have always roused so much interest. It is said that these were the portraits of two little boys who came to gaze, boy fashion, curiously into the window of the studio while Raphael was painting. His transformation of the mischievous, inquisitive, supremely boyish faces into the look of angelic rapture is one of the triumphs of the picture that have always made it of the greatest interest. Painted originally for an Italian Church it is now the treasure of the gallery of Dresden, where it occupies a room by itself that is more like a shrine to which devout worshippers come from all over the world and in which as in some sacred place the visitor distinctly lowers his voice and walks on tiptoe. Nothing tells more of what the picture means than to watch the crowds that come from all over the world to see it and the way in which it is almost worshipped by those whose opinion is worth the most.
