This paper discusses the life of Dylan Thomas and his autobiographical elements in his poetry. In fact, Thomas' poetry is so autobiographical in itself that one can learn a great deal about the poet just by reading them. His life can be summed up in a quote from Thomas himself, which reads, "I hold a beast, an angel, and a madman in me, and my inquiry is as to their working, and my problem is their subjugation and victory, downthrown and upheaval, and my effort is their self-expression".
