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. [Illustration: BROWNSOVER CHAPEL, WARWICKSHIRE] 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.
