vault: Nature of Vaults
A vault is generally composed of separate units of material, such as bricks, tiles, or blocks of stone, so shaped or cut that when assembled they form a tightly wedged and stable construction whose weight can be concentrated upon the proper supports. Vaults are also formed in a homogeneous material, as when built in concrete. In modern work ceilings in the form of masonry vaults are often merely of plaster applied against a curved framework of wood or metal. Since antiquity vault surfaces have been enriched at various times in diverse ways—with coffers, carvings, plaster decorations, mosaics, or frescoes.
