Summary
Early Renaissance architecture, though diverse, is unified by the era's belief in universal mathematical and geometric laws that govern the human body, the cosmos, and artistic creation, which architects sought to integrate into their designs.
Key Points
- Renaissance architects, unlike their medieval predecessors, sought common mathematical laws governing both the human body and the world, drawing inspiration from ancient philosophers who believed man was the measure of all things.
- The concept of harmonic proportion, exemplified by the spacing of frets on a lute, was believed to underlie diverse disciplines like pictorial perspective, musical mechanics, and even the architecture of the cosmos.
- Ancient scholars, like Cicero, provided witty explanations for why humans do not hear the "music of the spheres," comparing it to people living near a waterfall who eventually stop hearing the constant noise.
- Despite art historian Rudolf Wittkower's search for harmonic proportions in Renaissance buildings yielding little, the era's scientists enthusiastically sought universal mathematical or geometric patterns in all their studies.
- Renaissance treatises featured geometric diagrams—like inscribed polygons and circles—representing diverse concepts from ideal city plans and horoscopes to proportional grids for the human body and fencer's movements.
- Johannes Kepler's theory of the proportional structure of the cosmos, based on regular polyhedra inscribed within each other, was a significant geometric fantasy, though he later admitted its error.
- The visual persuasiveness of mathematical laws led Renaissance scientists to believe that geometric correspondences were physically tangible and real, influencing magical practices like alchemy and astrology.
- Renaissance architects, including Alberti, Leonardo da Vinci, and Bramante, consciously designed buildings like St. Peter's Basilica to conform to these geometric laws, often favoring regular, centric, or ideal shapes.
- The house of artist Mantegna, with its square exterior and circular internal courtyard, serves as a striking example of this scholarly architectural game, referencing Vitruvius's idea of the perfectly proportioned human body inscribed in a circle and a square.
- The ultimate visual representation of this Renaissance ideal is the human body, perfectly proportioned, fitting within a square and a circle inscribed within each other, sharing a common center.
