Plate XLVI. Internal Corridors

Plate XLVI. — In Nos. I to IX, inclusive, are shown various arrangements for the treatment of simple corridors, to all of which the plans Nos. III and VI apply. All these show the corridor divided into bays by means of flat pilasters, which may be coupled if occasion requires, as in No. VII. The coverings include flat ceilings with cross beams, barrel vaults, segmental and elliptical ceilings with coffering arranged in a variety of ways. The wall surfaces may be treated with a dado having capping and base and large panels above it, or they may be left plain, the base and capping of the pilasters being continued the length of the corridor. In Nos. X to XV, inclusive, are shown methods of using intersecting vaults over corridors, and the plan No. X applies equally whether the vaults are semi-circular or elliptical. In Nos. XIII and XV the vault springs from corbels or brackets, and a series of lunettes are formed above the impost. Intersecting vaults carried on corbels with well designed lunettes figured frequently in late eighteenth and early nineteenth century practice.
