And from Filippo Camerota, "Renaissance Descriptive Geometry: The
Codification of Drawing Methods," Picturing Machines 1400-1700, ed.by
Wolfgang Lefevre (Cambridge, MA: MIT Press, 2004), pp. 175-208:

"If the grid of Leon Battista Alberti derives from the method of
quadrettatura mployed by painters to enlarge their drawings, the
so-called 'sportello,' or window, of Albrecht Durer seems to show a
more direct link with the cartographers' grid....  The 'sportello' ...
represents a constant reference point in the literature on perspective
of the sixteenth and seventeenth centuries." (p. 180)
