Maltese cross
|
A shape that consists in its most basic form of an upright section and a
transverse section. The Latin cross has the shape of an
irregular dodecahedron with a single
(vertical) line of symmetry, and can be folded up to make a cube. Many Western
medieval churches have a Latin cross plan, with a long nave, north and south
transcepts, and a chancel or chevet.
The Greek cross has the shape of a "+" sign, has four lines
of symmetry, and is used as the emblem of the Red Cross organization. A
version of the Greek cross that has flared ends is also known as the crux
immissa or cross patée. A cross of Saint
Andrews is an ordinary Greek cross rotated through 45°, and
is also called the crux decussata; it served as the basis for the
multiplication sign. A cross of Saint Anthony takes the
form of a capital T. The Maltese cross is an irregular
dodecahedron whose cross pieces flange out from the center.
