Lias Graziose Corrin, Director of the Williams College Museum of Art, surveys Dion's most significant works and his ongoing investigations into natural history's obsession with categorizing nature. Critic and theorist Miwon Kwon talks to the artist about the interface between ecology and culture and the phenomenon of site-specific art. Norman Bryson, Professor of Art History at the University of California, San Diego, makes an iconographical analysis of The Library for the Birds of Antwerp, an indoor sculpture Dion constructed for 18 live African finches in 1993. The artist has selected a text by novelist Jon Berger, one of the first post-war thinkers to analyze the position of animals in a capitalist society. The book also features Dion's own provocative, witty and often lyrical writing on nature and his role as an artist engaged in environmental issues.
