Abstract
The construction of "palazzo" became popular in the period of Renaissance and its facade became new design theme for the architects. Serlio dealt with palazzo in his Fourth Book and Sixth Book as the other contemporary architects did in their books on architecture. This paper examines the method of composing facade of palazzo in Serlio's Fourth Book on architecture and clarifies the characteristics of his method. The results of the analysis in this paper are as follows ; 1) The method of constructing a porta is applied for composing the whole facade of palazzo, and is used especially to divide the width of the facade for making width of pillars. 2) The geometrical scheme of "matrix" which derived from the method of constructing a porta is possible to be used also in the rectangle for designing the facade. 3) Some differences between the rules of order and geometrical scheme method are adjusted to get the totality of facade design.
