Proportional design in L. B. Alberti's Tempio Malatestiano, Rimini

Systems of proportion provoked much controversy in the 1950s. Recent research has moved away from the study of musical theory, to that of number. Applying Classical arithmetic techniques to analyze Alberti's Tempio Malatestiano, this paper demonstrates that its design corresponds to Alberti's system based on geometrical features of the cube depicting ‘natural relationships that cannot be defined as numbers’. For today's practitioners, the paper asserts that architectural works are geometric constructs and reminds them that CAD is based on the arithmeticization of geometry.
