The last major verse written by Eliot and what Eliot himself considered his finest work, Four Quartets is a rich composition that expands the spiritual vision brought out in The Waste Land. Here, in four linked poems, spiritual, philosophical, and personal themes emerge through symbolic allusions and literary and religious references from both Eastern and Western thought. Four Quartets is the culminating achievement by a man considered the greatest poet of the twentieth century and one of the seminal figures in the evolution of modernism.
