This work was exhibited in the first post-war exhibition in Britain devoted to abstract art, which Heath helped to organise in 1951. It featured paintings by Kenneth and Mary Martin, Terry Frost, Victor Pasmore and Anthony Hill. Crucial for them all were the theories of harmonious proportion and dynamic composition of Hambidge, Power and Ghyka, who had all written on this subject. Heath was particularly impressed by Hambidge, basing compositions, such as ‘Climbing Composition Green and Blue’, on divisions of root angles. With trial pieces of cut card, which he rotated and shifted, he created a sense of constructed movement and organic growth. The result is what Heath described as a “rectangle of whirling planes”.
