As the years went by, a new fellowship with mankind, a large toleration and deep tenderness, bore golden fruit in his intercourse with this favoured band of young friends and disciples. As Walter Pater wrote of Michael Angelo, so might it be said of Blake, "This man, because the Gods loved him, lingered on to be of immense patriarchal age, till the sweetness it had taken so long to secrete in him was found at last. Out of the strong came forth sweetness, _ex forti dulcedo_." Among the new friends were John Varley, the father of English water-colours, as he has been affectionately termed, Richter and Holmes, both leaders of the new school. These men were the forerunners of Turner, Copley-Fielding, De Wint, Cotman, Prout, David Cox and William Hunt, and though in these days they are little remembered, and the glory of them has been eclipsed by their great successors, their somewhat timid and delicate work in South Kensington Museum will repay a visit and establish their pioneer claims to our regard. It was for John Varley that Blake drew the celebrated visionary heads, the only work of his with which he is associated by many people. Varley was by way of being an astrologer, and took the deepest interest in the occult and the spiritualistic. Blake's talk of visions, of the actual appearances vouchsafed him from the other world, had a significance to Varley's matter-of-fact mind much more vulgar and material than he intended. Our artist had cultivated imagination till it became vision, and what he thought, that he saw, for, as Mr. Smetham wrote, "thought crystallized itself sharply into vision with him." So that when his friend asked him to draw the portraits of men long dead and gone, such as Edward III, William Wallace, Richard I, Wat Tyler, or unknown personages, such as "the man who built the Pyramids," or "the man who taught Mr. B. painting in his dreams," and (most remarkable of all!) "the Ghost of a Flea," Blake had but to command his visionary faculty and summon before his gaze the desired sitters. The one which has been the most talked about is the Ghost of a Flea, and Varley gives the following description of the manner in which it sat for its portrait: "This spirit visited his (Blake's) imagination in such a figure as he never anticipated in an insect. As I was anxious to make the most correct investigation in my power of the truth of these visions, on hearing of this spiritual apparition of a flea, I asked him if he could draw for me the resemblance of what he saw. He instantly said, 'I see him now before me.' I therefore gave him paper and a pencil with which he drew the portrait.... I felt convinced by his mode of proceeding that he had a real image before him; for he left off and began on another part of the paper to make a separate drawing of the mouth of the flea, which, the spirit having opened, he was prevented from proceeding with the first sketch till he had closed it."
