Collins was a highly idiosyncratic artist, whose work was full of personal symbolism. He believed that we are all pilgrims on a journey back to the Paradise that we once knew, and that one of the functions of art was to help us on this journey. From the 1960s onwards Collins painted grand images of angels as spiritual messengers of light and love. This picture depicts an angel flying over a mountain, which has the form of a transparent curtain. The suggestion is that the angel's movement will cause the curtain to blow aside. For Collins, curtains represent a kind of gateway to the treasures of childhood or a divine state.
