The image in the painting is derived from a biology textbook illustration of a circulation system. Winters is interested in the organizing structures and systems beneath the seeming randomness of nature's complexity. His paintings are metaphors for social structures, means of communication and modes of living. They also represent psychological states and human relationships. The principal forms in the painting are inverted mirror images of each other and suggest mythical male and female figures. Winters is concerned to retain evidence of the history of the making of the painting and allows previous intentions and changes of mind to remain visible.
