Method of describing the Ionic Volutes, common, angular & elliptical

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.
