| Abstract |
It is essential to understand medieval and Renaissance theories of vision, we must begin by glancing at the Greek background. Gothic Architecture, was fundamentally a constructive practice, operating through very secretive traditions and geometric rules that could be applied directly on site. During the 15th century, architecture considered as a liberal arts and architectural ideas were conceived as geometric lineamenti, two dimensional, orthogonal drawings. Following the discovery of artificial perspective method by Brunelleschi and its codification by Alberti in his Della Pittura, early Renaissance architects experimented with this new technique in various ways. The fundamental difference between the natural perspective and artificial perspective lies the exact measurement and true scaling that required by linear perspective completely transformed the communication of information in the sciences and technical arts through pictorial illustration. Evidence in collections of drawings, paintings and buildings during Renaissance shows the use of sectional perspective drawings supplanted the standard orthogonal section as the conventional means of depicting buildings. This transformation marks the beginning of a practice that is a new mathematical and geometric rationalization of the image that radically departed from classical theories of vision. |
