Kyriological \Kyr`i*o*log"ic*al\, a. [See Curiologic.]
   Serving to denote objects by conventional signs or
   alphabetical characters; as, the original Greek alphabet of
   sixteen letters was called kyriologic, because it represented
   the pure elementary sounds. See Curiologic. [Written also
   curiologic and kuriologic.]
   [1913 Webster]

   Note: The term is also applied, as by Warburton, to those
         Egyptian hieroglyphics, in which a part is put
         conventionally for the whole, as in depicting a battle
         by two hands, one holding a shield and the other a bow.
