This paper is to analyse the perspective ratio or perspective design method adopted by Brunelleschi in the projection of the Old Sacristy of San Lorenzo in Florence. The part I of this paper divided in two parts is a proportion-analysis of the Sacristy's ground plan, which will serve as an introductory study for the part II dealing with the perspective-analysis of the elevation. Conclusions of the part I are, [1] The ratio or perspective ratio, defined by the author in a narrow sense as a numerical relation applied in this perspective design method, of (1 : 3) was strictly clarified. It was only possible through our new proportion-analysis method. [2] The perspective ratio does not concern with the orthogonal projection but with the perspective drawing; perspective ratio is tridimensional, it doesnot disclose itself in the ground plan which can only be represented as orthogonal projection. Any traditional proportion-analyses are, at any rate, not proved method for the composition of this architect. [3] The perspective-proportion-analysis made clear of the module composition of the Sacristy; the module is the width of the pilaster constituting in a pair the front of the chaple. The side of the large square which determines the plan of main space is exactly 18 modules, and the side of the small square for the chapel is 6 modules, which are all represented in the perspective drawing of the Sacristy.
