Dylan Thomas’s poems stay true to his Christian roots. In the poem “Do Not Go Gentle into That Good Night,” Thomas speaks of aging men and the road into darkness that follows age. Thomas writes, “Though wise men at their end know dark is right,/Because their words had forked no lightning they/Do not go gentle into that good night” (lines 4-6), in this stanza Thomas introduces going old and passing away. He states that the aging men know their time has come and gone and that they must leave the light of life and enter into the dark of night. This poem makes use of symbolism when referring to night/day and dark/light. This words play off of one another forming the idea of life as the light that burns on during the day forming one’s life, and death as the night leading the men away from the light into dark. It suggests that this transition from light to dark is the ending of life from old age.
