A Course in Theoretical and Practical Architecture; a new and easy method for making calculations of the proportions of the five orders of architecture of Giacomo Barozzi of Vignola

WHEN the author was occupied in the study of architecture

he was much impressed with the desirability of some

means of establishing the proportions of architectural

parts by simple calculations, so that, the general dimen-

sions being given, the details might be worked out in

conformity with established rules without too great

labor, but with a certainty of producing a harmonious

and well balanced design.
