The anta is generally crowned by a stone block designed to spread the load from superstructure (entablature) it supports, called an anta capitals when it is structural, or sometimes pilaster capital if it is only decorative as often during the Roman period. In order not to protrude unduly from the wall, these anta capitals usually display a rather flat surface, so that the capital has more or less a brick-shaped structure overall. The anta capital can be more or less decorated depending on the artistic order it belongs to, with designs, at least in ancient Greek architecture, often quite different from the design of the column capitals it stands next to. This difference disappeared with Roman times, when anta or pilaster capitals have design very similar to those of the column capitals.
