Trained as a painter, Brian Clarke (b. 1953) is well known for the architectural stained glass he has designed for secular and sacred buildings around the world. Through his painterly use of color and light, Clarke designs distinctive stained glass walls that introduce energy and vitality into the architectural spaces they inhabit. The Glass Wall, which measures more than 1,000 square feet, is dedicated to the late Linda McCartney, wife of the musician Paul McCartney. She was Clarke’s longtime friend and a distinguished photographer with whom he worked. The repeating fleur-de-lis motif is based on the lily, a flower that for centuries has served as a symbol of royalty. The abstract fields of color are inspired by the sky and water. Clarke chose this theme to reflect Linda McCartney’s love of lilies and his own interest in the colors and symbolism of British heraldry.
