Cymatium

This is not easy to define, but it may be called a capping moulding to certain parts and subdivisions of the orders in classic architecture: the projecting mouldings on the upper part of the architrave (except in the Doric order, where it is denominated tenia), the corresponding moulding over the frieze, and the small moulding between the corona and cyma of the cornice, are each called by this name; the small moulding, also, which runs round the upper part of the modillons of an cornice, is their cymatium; and the up per moulding,of the abacus of the Roman Doric capital is likewise so called; the upper mouldings which serve as a cornice to pedestals have occasionally the same name.
