O·ri·el n.  [Formerly written also oriol, oryal, oryall.]
  1. A gallery for minstrels. [Obs.]
  2. A small apartment next a hall, where certain persons were accustomed to dine; a sort of recess. [Obs.]
  3. Arch. A bay window. See Bay window.
  The beams that thro' the oriel shine
  Make prisms in every carven glass.   --Tennyson.
  Note: ☞ There is no generally admitted difference between a bay window and an oriel.  In the United States the latter name is often applied to bay windows which are small, and either polygonal or round; also, to such as are corbeled out from the wall instead of resting on the ground.
