In Katherine Sherwood’s newest body of work, the predominant theme is luck, examined in several of its most peculiar and intrinsically random forms. Set against a ground of paper glued onto canvas, signs and symbols of magic, gambling, and apocalypse reveal themselves gradually, almost coyly, with a little detective work. In many of these paintings, vaguely organic-looking figures and diagrams turn out to be “white magic seals of the spirits”: runes to which specific powers are ascribed. One confers wit and humor; another helps someone get ahead on the job, and a third grants peace of mind.
