Description: Shadows and Enlightenment
This book is a discussion of shadows and their part in our visual experience. More particularly, it juxtaposes modern with eighteenth-century notions about shadows with a view to benefiting from a tension between them. Some other historical periods have also had interesting ideas about shadows, of course, but the book is not about these. …

Description: Shadows and Enlightenment
6  Locke comes at the beginning not so much because he offered the eighteenth century a powerful theory of visual perception, though he did this too, as because, in the course of stating his theory in An Essay Concerning Human Understanding (1690), he framed in a particularly gripping way the issue of how we achieve a perception of the three-dimensional world from the two-dimensional array of stimulations on the retina. The form in which he first established the issue was: on what basis do …

11  The conviction common to all Enlightenment parties – nativist, empiricist, sensationalist, materialist, associationist – that shadow must somehow be quite central to our perception of the world, whatever the means and basis of our interpreting it, is so firm and compelling that effort is needed to disengage. It will help, at this point, to look at a picture. …

22  The term chiaroscuro or clair-obscur was used in two distinct senses in the eighteenth century, as people pointed out at the time. One is the working of light and shade in the world in general, a phenomenal thing. The other is the artistic arrangement of light and shade in pictures, an aesthetic and often normative thing (fig. 8). Present business is with the first, actual light and shade, but many of the most perceptive observers of this were visual artists, which is hardly …

34  The Rococo-Empiricist shadow-watchers were not quite a coterie but had some cultural coherence. Cochin, for example, had been a friend of Jombert since childhood; collaborated with Oudry in illustrating a famous edition of La Fontaine’s Fables by translating Oudry’s tonal wash drawings into linear terms for engraving (fig. 38); designed engravings for a book by Bouguer (a difficult and recessive man) and for several by Rousseau – including an allegorical portrait for the second edition …

Description: Shadows and Enlightenment
Leonardo da Vinci was an important source for eighteenth-century thinking about shadow, and he is also the first modem writer to offer a systematic view of shadow, as such: he addresses every objective kind of shadow and is still cited in the current literature (for instance, Koenderink and van Doorn, 1980). While his thought about vision in general clearly has a background in medieval and Renaissance optics, which has been well studied by Lindberg (1976) and others, his thought about shadow in …
