In architecture, the principal use of the term is to describe an arch composed of two ogees, mirrored left-to-right and meeting at an apex. Ogee arches were a feature of English Gothic architecture in the later thirteenth century.
A building's surface detailing (indoors or out) may have a molding with an ogee-shaped profile, consisting (going from low to high) of a concave arc flowing into a convex arc, with vertical ends; if the lower curve is convex and higher one concave, this is known as a Roman ogee, although frequently the terms are used as if they are interchangeable and for a variety of other shapes. Alternative names for such a true Roman ogee molding include cyma reversa and talon.
The cyma reversa form occurs in antiquity. For example, in ancient Persia, the Tomb of Cyrus
The ogee and Roman ogee profiles are used in decorative molding, often framed between moldings with a square section. As such it is part of the standard classical decorative vocabulary, adopted from architrave and cornice moldings of the Ionic order and Corinthian order. An ogee is also often used in the "crown molding" frequently found at the top of a piece of case furniture, or for capping a baseboard or plinth, or where a wall meets the ceiling. An ogee molding may be run in plaster or wood, or cut in stone or brickwork.
