Studies a set of images Tolkien deploys with great skill to represent essential thematic elements of the opposition between forces of the Alliance and the Enemy. These include the organic and natural symbols of Gondor, Rohan, Dol Amroth as opposed to the Eye of Mordor and White Hand of Isengard. McGregor’s observations on Saruman’s choice of imagery are particularly valuable in showing how Tolkien revealed the wizard’s attempts to play both sides even at the symbolic level.
