Many of Dylan’s poems drew from these childhood experiences of the rural Welsh countryside and he began writing of them in his notebooks at the age of 15 whilst attending Swansea Grammar School. Indeed his first and second collections of poems, entitled ’18 poems’ and ’25 poems’ respectively, drew heavily from these notebooks. Nearly two thirds of Dylan’s poetic works were written whilst he was still a teenager.The Life of Dylan Thomas, the famous Welsh poet
