Geometry & Design
The Geometric Foundations of Palladio's Architecture
Andrea Palladio never explained his design method. This dissertation identifies its geometric basis — revealing that the equilateral triangle and the ratio 1: √3/2 were at the heart of his process.

Cracking Palladio's Code
A video introduction to the geometric methods at the heart of Palladio's design process.
“Relationships which were previously overlooked become obvious, such as those based on the ratio of an equilateral triangle's base to its height: 1: √3/2.”

This research demonstrates that geometric templates based on the equilateral triangle were common practice among pre-modern architects — from ancient Roman builders through medieval master masons to Renaissance architects including Vitruvius, Villard de Honnecourt, Serlio, Vignola, and Scamozzi. The methods and principles demonstrated are of interest to historians, practicing architects, and anyone curious about the history of design.
