dome, the social banquet share.
Pope. 2. (Arch.) A cupola formed on a large scale.
&fist; "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.
&fist; 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.
