This Tree of Life is based on one of the 4,000 leaded art glass window and door designs featured prominently throughout the Darwin D. Martin House (Buffalo, NY 1903-05). Wright also created art glass designs for doors, skylights, back-lit ceiling panels, table lamps, and wall sconces. Wright's geometric abstraction of the ancient tree of life symbol using a square for the roots, straight lines for the trunk, and chevrons for the branches is found in several variations in the house.
