Escutcheon \Es*cutch"eon\, n. [OF. escusson, F. ['e]cusson, from
   OF. escu shield, F. ['e]cu. See {Esquire}, {Scutcheon}.]
   1. (Her.) The surface, usually a shield, upon which bearings
      are marshaled and displayed. The surface of the escutcheon
      is called the field, the upper part is called the chief,
      and the lower part the base (see {Chiff}, and {Field}.).
      That side of the escutcheon which is on the right hand of
      the knight who bears the shield on his arm is called
      dexter, and the other side sinister.

   Note: The two sides of an escutcheon are respectively
         designated as dexter and sinister, as in the cut, and
         the different parts or points by the following names:
         A, Dexter chief point; B, Middle chief point; C,
         Sinister chief point; D, Honor or color point; E, Fesse
         or heart point; F, Nombrill or navel point; G, Dexter
