Answer:An architectural order describes a style of building. In Classical architecture, each order is readily identifiable by means of its proportions and profiles as well as by various aesthetic details. The style of column employed serves as a useful index of the style itself, so identifying the order of the column will then, in turn, situate the order employed in the structure as a whole. The classical orders—described by the labels Doric, Ionic, and Corinthian—do not merely serve as descriptors for the remains of ancient buildings but as an index to the architectural and aesthetic development of Greek architecture itself.The Ionic order is notable for its graceful proportions, which produce a more slender and elegant profile than the Doric order. The ancient Roman architect Vitruvius compared the Doric module to a sturdy, male body, while the Ionic was possessed of more graceful, feminine proportions. The Ionic order incorporates a running frieze of continuous sculptural relief, as opposed to the Doric frieze composed of triglyphs and metopes.
