This catalog compiles nearly 100 paintings by French artist Fabrice Hyber (born 1961). Hyber moves seamlessly between the worlds of science and art; green is his preferred color and drawing, painting, sculpture and video his preferred mediums. Notably, the book is the first to showcase Hyber's La Vallée, a simultaneously momentous and intimate project set in a vast lush valley of Vendée, where he has planted over 100,000 trees since the 1990s. From an early age, he enjoyed collecting and planting seeds from service, pine, cypress and maple trees and observing the movements of streams and plants and the changes in the trees around him. In La Vallée, Hyber stays true to his childhood hobbies.
