Column cylindrical disks of alternating diameter. The shaft is almost never fluted. The proportions vary, but are generally similar to Doric columns. Height to width ratio is about 7:1. The Ionic column is considerably more complex than the Doric or Tuscan. It usually has a base and the shaft is often fluted (it has grooves carved up its length). The capital features a volute, an ornament shaped like a scroll, at the four corners. The height-to-thickness ratio is around 9:1. Due to the more refined proportions and scroll capitals, the Ionic column is sometimes associated with academic buildings. Ionic style columns
Ancient Greek architecture Ionic and foliate in the Corinthian. Doric and usually Ionic capitals are cut with vertical grooves known as "fluting". This fluting or grooving of the columns is a retention of an element of the original wooden architecture. The columns of a temple support a structure that rises in two main stages, the entablature and the pediment. The entablature is the major horizontal structural element supporting the roof and encircling the entire building. It is composed of three parts. Resting on the columns is the architrave made of a series of stone "lintels" that spanned the space between the columns, and
