Unlike other poets of his age who had turned to realism, Thomas kept his bright, often fantasy-inspired images; in many ways his work had been close to the romantic tradition. His main sources of inspiration were the Welsh folklore and mythology, his childhood memories of rural Wales (his play, entitled “A Child’s Christmas in Wales”) is performed every Christmas eve on the radio to this day. His radio play, entitled “Under Milk Wood”, perhaps the most well-known work by Thomas, is dedicated to life in a small Welsh town.
