Even lovers of Dylan Thomas’s poems are often puzzled by his habits of language, which sometimes take the form of unusual diction and unique perceptions. This study, on the hundredth anniversary of his birth, is a must-read for both Thomas’s fans and newcomers interested in an introduction to his works and the unique sensibility that created them. Chapters are devoted to his poetic perspectives, ranging from the microscopic to the cosmic; his unusual perceptions of the world, which some critics have described as those of an almost altered reality; his diction, or working vocabulary; his penchant for refurbishing clichés; his hilarious sense of humor and linguistic playfulness; his development as a poet; and his concern for sound, often resulting in a lofty, at times Biblical, though secular, tone. In summary, the study fully explores the heart and mind behind the poems, and shows why his work will always remain in the top rank of English poetry.
