It is difficult to describe the effect produced by this picture. The first sensation is a feeling of horror and disgust of the corpse. Its forehead is in shadow, its open eyes are turned upward, its mouth half shut as if in amazement; the chest is swollen, its legs and feet are rigid, the flesh is livid and looks as if it would be cold to the touch. In great contrast to this stiffened corpse are the living attitudes of the students, the youthful faces, the bright eyes, intent and full of thought, revealing, in different degrees, eagerness to learn, the joy of comprehension, curiosity, astonishment, the effort of the intellect, the activity of the mind. The face of the master is calm, his eye is serene, and his lips seem smiling with the satisfaction of intimate knowledge of his subject. The whole group is surrounded by an air of gravity, mystery, and scientific solemnity which imposes reverence and silence. The contrast between the light and shade is as marvellous as that between death and life. Everything is painted with infinite pains; it is possible to count the little folds of the ruff, the wrinkles in the face, the hairs of the beard. It is said that the foreshortening of the corpse is incorrect, and that in some places the finish degenerates into hardness, but universal approval places the "Lesson in Anatomy" among the greatest works of art in the world. Rembrandt was only twenty-six years old when he painted this picture, which consequently has the mark of his early work. The impetuosity, audacity, and unequalled assurance of his genius, which shine forth in his maturer works, are not yet seen, but his immense power of painting light, his marvellous chiaroscuro, his fascinating magic of contrast, the most original features of his genius, are all to be found here.
