Blake’s illustration to the Divine Comedy which is his last great work, represents the limpidness of his artistic state before the death. In 1922 the National Art-Collections Fund, London issued first the reproduction of this whole drawings. But this reproduction was not appreciated popularly because of the limited edition. In 1953 Albert S. Roe who is American specialist of art history, published for the first time the genuine study on Blake’s illustration to the Divine Comedy on the basis of the above-mentioned reproduction. Owing to Roe’s writings and other several literatures on Blake I explain the outline of Blake’s illustration to the Divine Comedy.
