BALL-FLOWER. WITH ROLL-MOULDING AND HOLLOW.

Diaper-work is very extensively used in this style in the backs of niches, on buttresses, and for covering spaces where other ornament could not well be used.

FOUR-LEAVED FLOWER, WITH FILLETED, ROUND, AND HOLLOW MOULDING.

Towards the end of the reign of Edward III. a great revolution in architecture was in progress. The change was first indicated by the introduction of straight lines among the flowing tracery of the windows, by which the beautiful freedom of their design was much impaired. This was followed by the foliage and other ornamental parts becoming more stiff and formal, and losing their truthfulness to nature.

It is curious to see how this idea of the perpendicular line and of a tendency to general squareness of form seems to have taken possession of the minds of the architects of the period; and it can only be attributed to the inherent love of variety and a desire for novelty. All things showed the approach of a change, which certainly was not the work of any one individual, but was rather the effect of a pervading idea, until William of Wykeham embodied and improved it, and brought out the new or Perpendicular style, which will be the subject of a future chapter.

Of the Domestic Buildings of the fourteenth century many good specimens yet remain. They were almost all built more or less for defence; and the more exposed the situation, the more were the defences increased, until it is difficult in many cases to say whether a building should be considered a house or a castle. The saying that "An Englishman's house is his castle" was at this time literally true. They were mostly moated, and contained but few rooms, one of which was much larger than the rest—the hall.

Of the military strongholds, or Castles, properly so called, many of the finest we possess were built during this period; among which may be mentioned Carnarvon, Chepstow, Kidwelly, Pembroke, Windsor, Clifford's Tower in York, Warwick, etc. The masonry of these is of the most perfect description; the courses, as at Clifford's Tower, York, being laid regularly through the whole extent of the building; thus showing that in castellated, as well as in every other branch of architecture, the Edwardian period stands pre-eminent.

The art of Sculpture was necessarily inseparable from ecclesiastical architecture. In our churches of the feudal ages the sculptured canopies, chantries, tracery, and statues are of singular merit and great poetic beauty in many instances, and in none more than in those of this period. They show a marked advance on the prior period. Both in the Early English and the Decorated orders we have exquisite specimens of sculpture, in spite of the destruction of the Reformation and the ravages of time. At York, Ely, Lichfield, Durham, Wells, and Westminster Abbey we can yet admire the labour of the sculptors of the eras of Henry III. and Edward I. In the cathedrals of Glasgow and Aberdeen, as well as in the splendid remains of Elgin and Holyrood, we have yet traces of it. The foliage, the trefoils, and quatrefoils of this period are peculiarly free, natural, and simple. In the Decorated order, at Croyland and Tintern, in the nave at York, in the magnificent choir at Lincoln, at Beverley, Ripon, and Carlisle, as well as in the beautiful ruin of Melrose, and a few churches in Scotland, we ought not to pass over the sculpture. On many of these graceful works the monks themselves are said to have laboured, and Walter de Colchester, sacristan of the abbey of St. Albans, is expressly celebrated by Matthew Paris as an admirable statuary.
