Another sketch of the same order is one which, although it does not belong to any public collection, is so important as to excuse a reference to it here. Through the great kindness of Mr. Frederick Shields, to whom it belongs, I am enabled to reproduce it. The two motives of the picture in Blair's "Grave," called "Death's Door," had been favourite ones with Blake, and used by him separately in "The Gates of Paradise," "The Marriage of Heaven and Hell," and "America," before he combined them so felicitously in the noble design which ranks among his best works. The sketch by Blake belonging to Mr. Shields would seem to represent the moment when he first realized the power and significance and beauty to be obtained by their incorporation in one design. Of this conception it must be admitted that it grew in Blake's mind after the first flashing vision of it, and was not from the beginning discernible in all the splendour to which it was eventually developed. Here is another beautiful and careful sketch of a female figure diving through the air. The force of her perpendicular flight, the attitude of one leg (the left, not the right, however) recall the "Reunion of the Soul and the Body," but this figure is undraped, and the arms are extended downwards, and indeed the differences are so numerous that it cannot be regarded as a sketch for that picture. In all probability it is a preliminary study for one of the numerous figures in the "Last Judgment" which he executed for the Countess of Egremont in 1807. Looking at the terse expressive little drawing, we are reminded of Blake's "golden rule of art"--"that the more distinct, sharp, and wiry the boundary line, the more perfect the work of art." Ah! but how he played with his line! "Wiry" at least it never was, say what Blake would! He never "painted" it, but felt his way along with sympathetic accuracy. And with what infinite inflexions of tenderness and strength did his pencil impress itself on the paper, indicating by that rare quality of touch more than form and modelling--almost, one had said--the very nature of the flesh of the figures he drew. Speaking of Blake's drawings, the manner in which he drew the muscular form of the male leg is very noticeable and strangely characteristic of him. Another line he felt very tenderly was the curved sweep of a woman's back from shoulder to indented waist, and downwards to delicate ankles and heels.

Shields] Let us linger a minute over another of what I may call Blake's shorthand sketches in the Print Room collection. It is undoubtedly the first idea for the picture entitled "The Spiritual form of Nelson guiding Leviathan, in whose wreathings are enfolded the nations of the earth." The finished picture appeared in Blake's own exhibition in 1809; it is now in the possession of T. W. Jackson, Esq., of Worcester College, Oxford.
