In
architecture the 'frieze' is the wide central section of an
entablature and may be plain or — in the
Ionic or
Corinthian order — decorated with
bas-reliefs. In an astylar wall it lies upon the
architrave ('main beam') and is capped by the
moldings of the
cornice.
In interiors, the frieze of a room is the section of wall above the picture rail and under the crown moldings or cornice. By extension, a frieze is a long band of
painted,
sculpted or even
calligraphic decoration in such a position, above eye-level. Frieze decorations may depict scenes in a sequence of discrete panels. The material of which the frieze is made may be
plasterwork, carved wood or other decorative medium.
In an example of an architectural frieze on the facade of a building, the octagonal
Tower of the Winds in the Roman
agora at
Athens bears relief sculptures of the eight winds on its frieze.
A 'pulvinated frieze' (or 'pulvino') is
convex in section. Such friezes were features of 16th-century Northern
Mannerism, especially in subsidiary friezes, and much employed in interior architecture and in furniture.
This concept has been generalized in the
mathematical construction of
Frieze patterns.
