CYMATIUM, the uppermost member of a classic cornice (q.v.), usually consisting of a projecting moulding. In the Greek Doric the cymatium occurs only upon the pediment cornices, returning along the sides only the depth of the pediment coping which it decorates. It is in the form of an ovolo or projecting convex moulding. The cymatium also takes an ovolo form in the Tuscan order, a cavetto, or concave, form in the Roman Doric and a cyma recta form, or moulding of double curvature, elsewhere.
