Perspective
The method by which the real three-dimensional space is represented in the table’s two-dimensional surface area. The basic rules, that governs each system of perspective is that the "remoted" objects appear to be smaller than these which are close to the viewer and that the parallel lines give the impression that somewhere in the distance are met. Starting from these findings and from the earlier system of construzione legitima, Florentine artists of the 15th century, such as Brunelleschi, Uccello, Piero della Francesca and, above all, L. B. Alberti, formulated the principles of linear perspective, based, among other things, on the proper use of the 'escape points' (those points where parallel lines seem to converge). The so-called atmospheric perspective exploits the color’s changes and tonal gradations in order to give the sense of distance (the phenomenal blue of distant mountains is a characteristic example of the effect of this perspective).
