The arches of this period are usually wider, and are distinguished from those of the Early English by the character of the mouldings. The ball-flower, consisting of a ball inclosed by three or four leaves, somewhat resembling a rosebud, is the favourite ornament, and a four-leaved flower is often used. Roll mouldings, quarter, half, or three-quarters round, frequently occur, and produce a very pleasing effect. The form of the arch is in many instances changed, and the graceful _ogee_ arch is introduced. The piers are round or octagonal in village churches, and in large churches are formed by a cluster of cylindrical shafts, not detached as in the preceding period, but closely united. The capitals are bell-shaped, and in large churches richly sculptured. Few of the wooden roofs remain, as they have been superseded in later times; but the marks of the old roofs may often be seen on the eastern wall of the tower. The windows are larger than those of the earlier style, and are filled with geometrical and flowing tracery of great variety and beauty. Small windows have heads shaped in the ogee or trefoil forms. Square-headed windows are not uncommon, especially in the clerestory, and in monastic churches circular windows are frequently met with. It is characteristic of this style that the carving is not so deep as in the previous work. We find groups of shallow mouldings separated by one cut deeper than the others.

The work is now more elaborate and richer, but lacks the majestic beauty of the Decorated style. It is easy to distinguish Perpendicular windows. They are larger than any which we have seen before; the mullions are carried straight up through the head of the window; smaller mullions spring from the heads of the principal lights, and thus the windows are broken up into panel-like compartments, very different from the beautiful curves of the Decorated style. Simple pointed arches are still in use, but gradually they become flattened; and the arch, commonly known as the Tudor arch, is a peculiar feature of this style. In village churches the mouldings of the arch are often continued down the piers without any capital or shaft. [Illustration: MERTON COLLEGE CHAPEL, OXFORD]
