It is interesting to observe that what (Georgia) O’Keeffe wanted to achieve was achieved from the start, and has hardly changed— the reducing of a landscape, a flower, or whatever to essence, the isolation of a powerful image which she then enlarges. Sometimes the effect is merely pictorial, and becomes banal and even sentimental (the famous skull with roses), but at her best a very few lines and blocks of color carry an explosive and mystical power. These are paintings that expand the mind, and I imagine living with one very happily.
