The lancet window is now introduced, at first of only one light, very narrow and long, and differing from the Norman window in having a pointed arch. At the east end of the chancel there are often three lancet windows, the centre one higher than the rest, with one dripstone over them. The first idea of window-tracery was the introduction of a plain lozenge-shaped opening over a double lancet window, the whole being covered by a single dripstone. From this simple arrangement it was not difficult to develop the beautiful bar-tracery which came into vogue in the subsequent period of English architecture. The capitals of the Early English style are bell-shaped, at first quite plain, but subsequently these are often covered with beautifully sculptured foliage of a very graceful character. Circular windows at this period came into vogue in the gables of churches. They were either plain or quatre-foiled. Norman towers were sometimes capped with spires in the thirteenth century. The walls are not so thick or massive as in the Norman period, and the buttresses are stouter and more numerous, and project further from the wall. Flying buttresses were also introduced at this period. We can generally distinguish Early English work from that of the Norman style by its lightness and elegance, as compared with the roughness and massiveness of the latter; and its plainness and simplicity sufficiently distinguish it from that of the Decorated period.
The Decorated style (1275-1375) which prevailed during the reigns of the three Edwards was ushered in by a period of Transition, during which there was gradually developed the most perfect style which English architectural skill has ever attained. In the thirteenth century our builders were striving to attain the highest forms of graceful design and artistic workmanship. In the fourteenth their work reached perfection, while in the fifteenth there was a marked decline in their art, which in spite of its elaborate details lacked the beauty of the Decorated style.
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.
