Architect and author Steve Bass presents the third and final part of his course, "A Theory of Proportion in Architecture & Design." To complete the previous installments of the course, watch Part I and Part II.
This full three-part course provides an overview of the concept of proportion as a design tool in traditional architecture, including an explanation of the idea of symbolic or qualitative number; an introduction to Pythagorean and Platonic numerical philosophy; the nature of beauty, its relation to number, and its positive, healthful effects; the derivation of the ancient musical octave and its use as a guide to harmony; a discussion of the Golden Section, its mathematics, geometry, relation to philosophy, and particularly its role as a geometrical “logos”; and the connection of all these ideas to the numerical-geometrical canons of classical architecture.
These ideas are applied to historical archetypes, such as the four column portico, through demonstrations using arithmetic, geometric, and harmonic ratio methods of application to achieve harmonic and uplifting design outcomes. The course may be taken as an introduction to these ideas or as a review for those who have some background with the subject.
Viewers are encouraged to download the accompanying booklet below and actually draw the constructions demonstrated in the video.
