Wilkinson quotes David Sylvester and Robert Melville when discussing the sources of Moore's inspiration for his drawings of points practically touching, for example HMF 1496, and for the sculpture Three Points 1939-40 (LH 211). In 1952, standing below Michelangelo's Creation of Adam in the Sistine Chapel, Moore turned to Ann Garrould and remarked on the charge of electricity which seemed to flow between the two fingers, adding: 'It's a bit like what I intended in a sculpture I did just before the war - creating a sense of tension.'
