In plural: abacuses or abaci; from Latin: abacus; from Greek: ábaks.

A square plate constituting the uppermost part of the capital (head) of a column. In the Doric order, the abacus together with the echinus form the actual capital; in Ionic and Corinthian orders, it is a thin profiled and decorated plate; in Ionic and Composite orders, the sides of the abacus are recessed and decorated with a rosette. In the arcade system, in late antique and medieval art, the abacus often turned into impost.
