J. R. R. Tolkien had great sensitivity to the details, delights, and vitality of the natural world. Throughout his writings, and especially in episodes involving the Ents and the land of Rohan, he pays exquisite attention to the lives and even personalities of trees, leaves, trunks, roots, atmosphere, streams, lichen, weather, rocks, cliffs, sun, moon, wind, rain, grass, soil, and other specific elements of creation. In this course, we will read these passages slowly and carefully, trying to appreciate every detail, and discuss what we can learn about caring for flora, fauna, and the planet itself from his loving descriptions and from some smart commentaries on his work.
