Architectural perspective in Italian paintings of the 14th century

This paper discusses the system of the pictorial depth representation, typical for Giotto and other Italian artists of 14th century. Differing from the linear perspective, this system has a number of peculiar features, and its own consistent logic for the formation of pictorial space. The paper is especially focused on the contradictions of such a system, which lead to the appearance of impossible figures, and the ways in which the artists solved these difficulties.
