This presentation analyses theories of visual representation extracted from various mostly unpublished texts from the 15th-century University of Vienna: disputation materials, commentaries on Aristotle’s De anima and John Peckham’s Perspectiva communis, and compendia of natural philosophy. Two idiosyncratic tenets developed and defended by Vienna masters are examined. The first claim proposes that visual representations are extended and, in some way, ‘shaped’ according to the objects seen, with parts distinctly representing the respective parts of the latter. The second claim is that acts of external senses are a sort of concepts signifying the substance of the object seen and connoting its colour, shape, place and other accidents. Thus, the Vienna masters advocated and expanded the Buridanian idea of the rich content of visual representation: we do not see only colours, but objects as modified by diverse visible properties. It is investigated whether any Vienna author endorsed both claims, and whether they are compatible in principle.
