A volute is a spiral scroll-like ornament that forms the basis of the Ionic order, found in the capital of the Ionic column. It was later incorporated into Corinthian order and Composite column capitals. Four are normally to be found on an Ionic capital, eight on Composite capitals and smaller versions (sometimes called helix) on the Corinthian capital.
The word derives from the Latin voluta ("scroll"). It has been suggested that the ornament was inspired by the curve of a ram's horns, or perhaps was derived from the natural spiral of the ovule of a common species of clover native to Greece. Alternatively, it may simply be of geometrical origins.
The ornament is used as an element of Renaissance and Baroque architecture and is a common decoration in furniture design, silver and ceramics. A method of drawing the complex geometry was devised by the ancient Roman architect Vitruvius from classical buildings and structures.
