John Lincoln's system of drawing or doodling using hundreds, perhaps thousands of circles drawn with a fibre-tip pen is a technique of automatic drawing derived from what the surrealist André Breton called "Pure psychic automatism". The results can be understood at a number of levels from simple diagrams to symbols and visual metaphors, all of which offer analogies for human thought and experience: images which touch on the unconscious. Giles Watson's poems are creative responses to John Lincoln's pictures, drawing on science, experience and imagination. A little treasury of the mysterious and archetypal, this collection provides a delightful counterpoint to other books in the "Green Pulse" series.
