A sure guide to builders, or, The principles and practice of architecture, geometrically demonstrated, and made easy, for the use of workmen in general : wherein such geometrical definitions, theorems, problems, &c. as are basis of architecture, are render'd easy and intelligible to every capacity ...
A 1729 London builders' manual by Batty Langley, with William Mears and others as publishers, written to teach workmen the geometry underlying architecture in plain terms. Its plates are engraved diagrams of classical orders, arches, vaults and cornices, drawn with dimension figures and measured elevations. A designer can take from them the clean proportional logic of column, arch and entablature drawn as working plans.
