Most classical columns arise from a basis, or base, that rests on the stylobate, or foundation, except for those of the Doric order, which usually rest directly on the stylobate. The basis may consist of several
Corinthian order banding that forms the base of the capital, recalling the base of the legendary basket. Most buildings (and most clients) are satisfied with just two orders. When orders are superposed one above another, as they are at the Flavian Amphitheater—the Colosseum—the natural progression is from sturdiest and plainest (Doric) at the bottom, to slenderest and richest (Corinthian) at the top.
