Palladio's Book IV: Four and a Half Centuries of Inspiration with Calder Loth
1.5 AIA CES Learning Units|Elective and 1.5 credits towards the Certificate in Classical Architecture
Andrea Palladio’s The Four Book on Architecture is unquestionably the most influential architectural treatise ever written. The treatise’s Book IV consists of Palladio’s illustrations and descriptions of twenty-five Roman temples. From his study of their ruins Palladio produced ninety-seven pages of elevations, sections, plans, and details depicting his concepts of the temples’ original appearance. His lavish plates offered for the first time a credible vision of the grandeur and beauty of ancient Roman design. Book IV’s seductive images have served as a primary design source for many great classical works henceforth. This video lecture offers a glimpse of the riches of Book IV and presents numerous examples of structures that drew inspiration from Palladio’s plates. A primary intent of this presentation is to encourage current practitioners to mine Book IV’s many resources for enriching contemporary classicism.
