The internationally acclaimed artists Libenský and Brychtová pioneered, explored, developed, and defined glass as a medium for contemporary sculpture. The career in glass of this husband-and-wife team spanned more than 45 years. Their art explores ideas about light, color, space, and transparency. The dark gray sculpture Imprint of an Angel II belongs to the last series of sculptures that Libenský and Brychtová made together. This series explores themes of mortality and the redemption of the human spirit, which the artists call the “inner light.” The abstract shape of this sculpture, which is based on a man’s shoulders and chest, has been described by the artists as a “vestment” or a “shroud.” For them, it represents the physical impression of an “angel,” which is the divine part of man.
