those Visionary Heads, or Spiritual Portraits of remarkable characters, whereof all who have heard of Blake have heard something. Varley it was who encouraged Blake to take authentic sketches of certain among his most frequent spiritual visitants. The Visionary faculty was so much under control that, at the wish of a friend, he could summon before his abstracted gaze any of the familiar forms and faces he was asked for. This was during the favourable and befitting hours of night; from nine or ten in the evening, until one or two, or perhaps three and four, o'clock in the morning; Varley sitting by, 'sometimes slumbering, and sometimes waking.' Varley would say, 'Draw me Moses,' or David; or would call for a likeness of Julius Caesar, or Cassibellaunus, or Edward the Third, or some other great historical personage. Blake would answer, 'There he is!' and paper and pencil being at hand, he would begin drawing, with the utmost alacrity and composure, looking up from time to time as though he had a real sitter before him; ingenuous Varley, meanwhile, straining wistful eyes into vacancy and seeing nothing, though he tried hard, and at first expected his faith and patience to be rewarded by a genuine apparition. A 'vision' had a very different signification with Blake to that it had in literal Varley's mind.
Sometimes Blake had to wait for the Vision's appearance; sometimes it would not come at call. At others, in the midst of his portrait, he would suddenly leave off, and, in his ordinary quiet tones and with the same matter-of-fact air another might say 'It rains,' would remark, 'I can't go on,—it is gone! I must wait till it returns;' or, 'It has moved. The mouth is gone;' or, 'he frowns; he is displeased with my portrait of him:' which seemed as if the Vision were looking over the artist's shoulder as well as sitting vis-à-vis for his likeness. The devil himself would politely sit in a chair to Blake, and innocently disappear; which obliging conduct one would hardly have anticipated from the spirit of evil, with his well-known character for love of wanton mischief.
