or Spandrel (formerly splaundrel, a word of unknown origin), in architecture, the space between any arch or curved brace and the level label, beams, &c., over the same. The spandrils over doorways in Perpendicular work are generally richly decorated. At Magdalen College, Oxford, is one which is perforated, and has a most beautiful effect. The spandril of doors is sometimes ornamented in the Decorated period, but seldom forms part of the composition of the doorway itself, being generally over the label.
