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
Doric order three orders are used one above the other, it is usual for the Doric to be at the bottom, with the Ionic and then the Corinthian above, and the Doric, as "strongest", is often used on the ground floor below another order in the storey above. In their original Greek version, Doric columns stood directly on the flat pavement (the "stylobate") of a temple without a base. With a height only four to eight times their diameter, the columns were the most squat of all the classical orders; their vertical shafts were fluted with 20 parallel concave grooves; and they
