Xu Bing
A Book from the Sky () is the title of a book produced by Chinese artist Xu Bing in the style of fine editions from the Song and Ming dynasties, but filled entirely with meaningless glyphs designed to resemble traditional Chinese characters. The book, which consists of four volumes totaling 604 pages, was printed in a single print run of 126 copies between 1987 and 1991, and was first publicly exhibited in October 1988, in Beijing's China Art Gallery.
