Aeolian Winds and the Spirit in Renaissance Architecture introduces new dimensions of thinking about architectural theory. Investigating Renaissance pneumatic architecture with respect to other disciplines of arts and sciences, the collected essays substantiate the thesis that pneuma (air, wind, spirit, soul) is a fundamental link for establishing harmony among the human body, a building, and the cosmos. While much of sixteenth and seventeenth century scholarship has been devoted to the mathematics of ideal architecture, the book proves that essence, wind and ventilation are all part of the classical principles of building, and that one of the primary goals of Renaissance architects was to enhance the powers of pneuma so as to foster the art of well-being. This volume, written by leading architectural historians and scholars, delineates ancient and Renaissance theories and practice of pneumatology, and indicates a link to contemporary environmental questions. It examines Anaximenes, Hippocrates, Galen, Trento, Romano, Alberti, Serlio, Palladio, Scamozzi and other thinkers and humanists. Moreover, the essays illustrate the most famous examples of hygienico-therapeutic villas, including Rotonda, La Rocca Pisana and Eolia, a pneumatic model of Renaissance Venetian architecture.
