Hardcover, 6.75 x 9.5 in. / 360 pgs / 356 color / 48 bw. Intangible Heritage presents both Marx’s work and teachings, compiling nine of his most seminal lectures written between 1962 and 1983. Illustrated with images of his mosaics and detailed maps, the volume groups Marx’s lectures into three thematic sections: in the first, he explores how botanical expeditions, such as his trip to the Amazonas in 1983, informed his thinking about urban landscapes; in the second, Marx traces facets of landscape architecture to their ancestral origins and discusses the role of subjectivity in the profession; in the third, he delves into society's responsibility to protect the environment
