Abstract : Two-dimensional views of three-dimensional space are based om convention. Renaissance perspectival drawing invented by Brunelleschi is one of them.It caused difficulties to fifteenth and sixteenth century and later artists, although readily taken up by those understanding mathematics. Raphael was amongst those who did not seem to have understood some of its elements: this is illustrated in the first section. The second addresses the question of whether a squint may manifest in an artist's work. Giorgione's ocular anomaly was wwell documented by several of his self-portraits, and reference is made to some of his paintings with a special analysis of The Tempest. The final section deals with chromatic stereoscopy, with particular reference to the work of Durer. Hos apparently anomalous spatial sense is tentatively explained with the suggestion that he may have suffered from a defect of colour vision (protanomaly).- Slides
