Lectures on architecture, consisting of rules founded upon harmonick and arithmetical proportions in building ...
Robert Morris's 1759 treatise on architecture, published in London by Robert Sayer, sets out building rules based on harmonic and arithmetical proportion for architects and builders of the period. The four plates show measured plan and elevation drawings of façades and buildings in engraved line work, with dimensioned scales and figure annotations a designer could use for classical proportion studies.
