Order
An order is the total assemblage of parts comprising the column and its appropriate entablature. The primary divisions of the column are base, shaft and capital. The primary divisions of the entablature are architrave, frieze and cornice. A pedestal under the column is not an essential part of the order but appropriate pedestals are given by the theorists from Serlio onwards. 2. Any of several concentric rings of masonry forming an arch, especially when each projects beyond the one below. 3. A condition of logical, harmonious, or comprehensible arrangement in which each element of a group is properly disposed with reference to other elements and to its purpose. (Summerson, 1963)
