One of the techniques developed during the Renaissance period is Geometry. In this aspect, Art binds itself to Mathematics to demonstrate its authority as an intellectual activity. The reading of theoretical texts and the analysis of the geometric construction of the paintings of the time allows to observe a new three-dimensional relation in a flat support. The learning of the technique allows to know the basic structure of the space and to make proportional associations among its components. The perspective was the "symbolic form" of the Renaissance, for it caused a revolution in conception and practice in painting, and which is still practiced today to transform ideas into matter.
