OBSERVATIONS
ON
VAULTS.*
INTRODUCTION.
An inquiry into the different forms of Vaults, and acomparison of their respective merits, by renderingthem more familiar to the architect, may lead to thesubstitution of them for wooden floors and roofs inmany cases, where, in respect of their superior secu-rity and durability, and, it may be added, beauty,they would be peculiarly desirable. The changes,which have taken place at certain periods in the formsof vaults, will in some measure account for thealterations in the styles of architecture, which havecharacterised different ages ; and their genesis willexhibit, perhaps, the most comprehensive and curiousexamples of the application of geometry.
Vaults which rise from walls are of a simple cha-racter •, those which rise from piers and pillars aremore complex.
