Tu, technical images, and their relationship to written text in the production of technical knowledge is explored by mostly European scholars of Chinese history and culture. They consider graphics both as symbolic mediation and as technical illustrations across a broad range of graphic forms and categories of specialized knowledge, from metaphysical cosmograms and magical talismans to mathematical diagrams and coroner's charts. The final sections look at the era of print culture and Western influences. Annotation ©2008 Book News, Inc., Portland, OR (booknews.com)
