is one of the most moving poems Eliot wrote, and perhaps the "most perfect", though it was not well received by everyone. The poem's groundwork of orthodox Christianity discomfited many of the more secular literati. Old Possum's Book of Practical Cats In 1939, Eliot published a book of light verse, Old Possum's Book of Practical Cats. ("Old Possum" was Ezra Pound's friendly nickname for Eliot.) The first edition had an illustration of the author on the cover. In 1954, the composer Alan Rawsthorne set six of the poems for speaker and orchestra in a work titled Practical Cats. After Eliot's death, the book was the basis of the musical Cats by Andrew Lloyd Webber, first produced in London's West End in 1981 and opening on Broadway the following year. Four Quartets Eliot regarded Four Quartets as his masterpiece, and it is the work that most of all led him to being awarded the Nobel Prize in Literature. It consists of four long poems, each first published separately: "Burnt Norton" (1936), "East Coker" (1940), "The Dry Salvages" (1941) and "Little Gidding" (1942). Each has five sections. Although they resist easy characterisation, each poem includes meditations on the nature of time in some important respect—theological, historical, physical—and its relation to the human condition. Each poem is associated with one of the four classical elements, respectively: air, earth, water, and fire.

The meditation leads the narrator to reach "the still point" in which there is no attempt to get anywhere or to experience place and/or time, instead experiencing "a grace of sense". In the final section, the narrator contemplates the arts ("words" and "music") as they relate to time. The narrator focuses particularly on the poet's art of manipulating "Words [which] strain, / Crack and sometimes break, under the burden [of time], under the tension, slip, slide, perish, decay with imprecision, [and] will not stay in place, / Will not stay still." By comparison, the narrator concludes that "Love is itself unmoving, / Only the cause and end of movement, / Timeless, and undesiring." "East Coker" continues the examination of time and meaning, focusing in a famous passage on the nature of language and
