The Decorated Period dates from 1300 to 1377. It is also called the Middle Pointed, Geometrical Pointed and the Flowing, or Curvilinear, and also the Edwardian, because it covers the reigns of Edward I., II. and III. Exeter Cathedral is a superb example of this style. The nave of York Minster and the lantern of Ely are also noteworthy illustrations. “The general appearance of Decorated buildings is at once simple and magnificent; simple from the small number of parts, and magnificent from the size of the windows, and the easy flow of the lines of tracery. In the interior of large buildings we find great breadth, and an enlargement of the _clerestory_ windows, with a corresponding diminution of the _triforium_, which is now rather a part of the _clerestory_ opening than a distinct member of the division. The roofing, from the increased richness of the groining, becomes an object of more attention. On the whole the nave of York, from the uncommon grandeur and simplicity of the design, is certainly the finest example; ornament is nowhere spared, yet there is a simplicity which is peculiarly pleasing.”--(Rickman.) “The Decorated style is distinguished by its large windows divided by mullions, and the tracery either in flowing lines, or forming circles, trefoils and other geometrical figures, and not running perpendicularly; its ornaments are numerous and very delicately carved, more strictly faithful to nature and more essentially parts of the structure than in any other style. There is a very fine window with reticulated tracery and richly moulded in the south walk of the cloisters at Westminster. No rule whatever is followed in the form of the arch over windows in this style; some are very obtuse, others very acute and the ogee arch is not uncommon. Decorated tracery is usually divided into three general classes--geometrical, flowing and flamboyant; the variety is so great that many sub-divisions may be made, but they were all used simultaneously for a considerable period. The earliest Decorated windows have geometrical tracery; Exeter Cathedral is, perhaps, on the whole, the best typical example of the early part of this style. The fabric rolls are preserved, and it is now evident that the existing windows are, for the most part, of the time of Bishop Quivil, from 1279 to 1291. In some instances windows with geometrical tracery have the mouldings and the mullions covered with the ball-flower ornament in great profusion, even to excess; these examples occur chiefly in Herefordshire, as at Leominster; and in Gloucestershire, as in the south aisle of the nave of the Cathedral at Gloucester: they are for the most part, if not entirely, of the time of Edward II. What is called the netlike character of tracery, from its general resemblance to a fisherman’s
