The Claude Glass : Use and Meaning of the Black Mirror in Western Art

In this first full-length study of a largely forgotten optical device from the eighteenth century, Arnaud Maillet reconfigures our historical understanding of visual experience and meaning in relation to notions of opacity, transparency, and imagination. Many are familiar with the Claude glass as a small black convex mirror used by artists and spectators of landscape to reflect a view and make tonal values and areas of light and shade visible.

In a groundbreaking account, Maillet goes well beyond this particular function of the glass and situates it within a richer archaeology of Western thought, exploring the uncertainties and anxieties about mirrors, reflections, and their potential distortions. He takes us from the magical and occult background of the “black mirror,” through a full evaluation of its importance in the age of the picturesque, to its persistence in a range of technological and representational practices, including photography, film, and contemporary art. The Claude Glass is a lasting contribution to the history of Western visual culture.
