The Claude glass. Use and meaning of the black mirror in Western

Sobre el libro The Claude glass. Use and meaning of the black mirror in Western de Arnaud Maillet publicado por Zone al 2004:

"many are familiar with the Claude glass as a small black convex mirror used by artists ans spectators of landscape to reflect a view an make tonal values and areas of light and shade visible. Millet [...] goes beyond this particular function of the glass ans situates it within a richer archaeology of Western thought, exploring the uncerntainties ans anxieties about mirrors, reflections and theri potential distorsions".
