The Roman Tuscan order is a column style based on the Greek Doric order. Roman architects adopted the column styles of the Greeks, but they did not always do so in a precise manner. The Roman column style known as the Tuscan order is considered to be a degenerate from of the Greek Doric style because it is the least ornate order in the canon of classical column orders, although it is also viewed by some architectural historians as the most solid.
Columns that belong to the Tuscan order have a smooth shaft which tapers up to a width of about 75 percent of the lower portion. The capital, which is the uppermost portion of the column, is comprised of three sections of equal height. Two parts make up the base: a cushion and a circular plinth.
Although the Tuscan order is considered to be similar to the Doric order in its simplicity, the ratios of its dimensions bear a closer resemblance to the Ionic order. The strength and simplicity of the Tuscan order make it easy to construct, and the style found its way into vernacular and Georgian architectural designs for structures in New England and Ohio as recently as those built in the 19th century.
