Dome \Dome\, n. [See {Doom}.]
   Decision; judgment; opinion; a court decision. [Obs.]
   --Chaucer.

Dome \Dome\, n. [F. d[^o]me, It. duomo, fr. L. domus a house,
   domus Dei or Domini, house of the Lord, house of God; akin to
   Gr. ? house, ? to build, and E. timber. See {Timber}.]
   1. A building; a house; an edifice; -- used chiefly in
      poetry.

            Approach the dome, the social banquet share. --Pope.

   2. (Arch.) A cupola formed on a large scale.

   Note: ``The Italians apply the term il duomo to the principal
         church of a city, and the Germans call every cathedral
         church Dom; and it is supposed that the word in its
         present English sense has crept into use from the
         circumstance of such buildings being frequently
         surmounted by a cupola.'' --Am. Cyc.

   3. Any erection resembling the dome or cupola of a building;
      as the upper part of a furnace, the vertical steam chamber
      on the top of a boiler, etc.

   4. (Crystallog.) A prism formed by planes parallel to a
      lateral axis which meet above in a horizontal edge, like
      the roof of a house; also, one of the planes of such a
      form.

   Note: If the plane is parallel to the longer diagonal
         (macrodiagonal) of the prism, it is called a macrodome;
         if parallel to the shorter (brachydiagonal), it is a
         brachydome; if parallel to the inclined diagonal in a
         monoclinic crystal, it is called a clinodome; if
         parallel to the orthodiagonal axis, an orthodome.
         --Dana.
