Classical Orders: The Ancient Architectural Cannon
An order is the principal component of a Classical building, composed of base, shaft, capital and entablature.
The five Classical orders are the ‘Tuscan’, ‘Doric’, ‘ Ionic’, ‘Corinthian’ and ‘Composite’, which all vary in size and proportion.
The Tuscan, a Roman order, is the plainest and largest.
The Doric is found in two distinct varieties: Greek Doric IS characterized by its fluted shaft and lack of base; Roman Doric may have a fluted or unfluted shaft and also has a base. The Ionic is Greek in origin, but was used extensively by the Romans; it is distinguished by its voluted capital and often fluted shaft.
The Corinthian is characterized by the acanthus leaves decorating its capital.
The Composite is a Roman creation that combines the volutes of the Ionic with the acanthus leaves of the Corinthian.
