treated with ornamental rib-work, in the same manner as the other and less lofty rooms: the hall at Knole presents an example of this kind of treatment (Fig. 145). At Kirby there is an unusual form of roof, neither flat nor open timbered, but a kind of barrel-vault formed of four straight faces (Fig. 147); each face is divided into large panels by moulded and cut oak ribs of large size, and each panel has a curved diagonal rib resembling the wind-braces of a Gothic roof. The panels are filled with boarding at the back of the ribs. [Illustration: 146.--WOLLATON HALL, NOTTINGHAMSHIRE. THE ROOF OF THE GREAT HALL (1580-88).] [Illustration: PLATE XLV.

Leaving the hall for one of the smaller rooms, we find much the same kind of treatment, but here the ornamental ceiling plays an important part in the decoration. The walls were panelled, more or less richly, from floor to ceiling, and were crowned with a carved frieze and projecting cornice, above which started the ceiling ribs. The great chamber at South Wraxall (Plate XLVII.) gives a good idea of the whole effect, but the coved ceiling is somewhat exceptional, and so also is the great projection to the left. This is a mass of masonry required to carry the roofs, but the designer, who found himself obliged to leave it (for this room was contrived in an old house), resolved to face the matter boldly and make an ornamental feature of it. It will be noticed that though the panelling here is quite simple, a good deal of character is obtained by varying the size of the panels in a systematic manner. In the old Town Hall at Leicester there is a good panelled room (Plate XLVIII.), with a handsome chimney-piece and a special seat for the mayor. The work, which bears the date 1637, is simple in design, but is quite as effective and rather more pleasing than many of the more elaborate effects of the time, in which the impression is conveyed that the designers over-exerted themselves.
