cyma recta
Quick Summary
A cyma is a molding in architecture characterized by an S-shaped curve. This curve is formed by the union of a concave and a convex line. In architectural design, a cyma recta is a projecting molding composed of a cavetto (concave curve) above an ovolo (convex curve), creating a continuous double curve. It is often used as a crowning element and is sometimes called a cymatium. When used as a base, the convex portion is positioned at the top. Moldings, in general, are elements that define or outline edges and surfaces in architecture, and their design often considers the shadows they cast.12
