| Ogee — or Ogyve (Old Fr.), a moulding formed by the combination of a round and hollow, part being concave and part convex. In Classical architecture ogees are extensively used, and are always placed with the covex part upwards, (see Cyma Reversa): among the Greeks they were formed with quirks at the top, but by the Romans these were very frequently omitted.
In Gothic architecture also ogees are very abundantly employed, but they are, quite as often as not, used with the hollow part upwards, and in such cases might in strictness be called cyma recta; they are almost invariably quirked: in Norman work they are very rarely found, and are less common in the Early English than in either of the later styles. This moulding assumed different forms at different periods, and the variations, although not sufficiently constant to affod conslusive enidence of the date of a building, often impart very great assistance towards ascertatining its age: fig. 1 is Early English; fig 2 isused at all periods, but less frequently in the Early English than in the other styles; fig. 3 is Decorated; fig. 4 is late Perpendicular.
The term Ogee os also applied to a pointed arch, the sides of which are each formed of two contrasted curves.
| | Order — in Classical architecture, a column entire, consisting of base, shaft, and capital, with an entablature. There are usually said to be five orders, the Tuscan, Doric, Ionic, Corinthian, and Composite; but the first and last, sometimes called the two Roman orders, are little more than varieties of the Doric and Corinthian, and were not used by the Greeks.
| | Ovolo — (Ital.), a convex moulding much used in Classical architecture; in the Roman examples it is usually an exact quarter of a circle, but in the Grecian it is flatter, and is most commonly quirked at the top: in middleage architecture it is not extensively employed; it is seldom found in any but the Decorated style, and is not very frequent in that(See also Column.)
