This is a poem about the joy and sadness that come with the flash of a fiery life soon snuffed out with nothing but a sigh. It focuses on sadness as those we care about enter too gently into that good night. Of those who left before their time. Because this poem was written specifically for Thomas' dying father, it is all the more poignant because of the emotional weight the words convey. This poem radiates intensity, especially the beginning of the line: Wild men who caught and sang the sun in flight is simply a beautiful poem. Addressed to the poet's father as he approaches blindness and death. The relevant aspect of the relationship was Thomas' deep respect for his father, tall and strong in his passionate mind but now tamed by illness and the passage of time. Acceptance of death and subsequent peaceful rest are cast aside in favor of a rage so blind it almost mirrors the vigor of childhood frustration at the nature of things we are powerless to change. Furthermore, the poem is as much about the loss of love and feelings of those left behind as it is about death itself. The meaning of the poem remains shrouded in metaphors such as references to the night as "good". He recognized that his father was somewhere where he had not seen him, and perhaps he saw what he could not. Thomas was not ready to let go of such an important part of his life, even though his father was facing an irreversible path, and Thomas' pain was perhaps even greater. His declaration of this love and pain remains poignant. Maybe his father's fading feelings should have been more important than his own anger. These emotions seem to run unchallenged throughout the poem, even as the style invites structure and discipline within the theme of “night” and “light.” In the tercets, Thomas provides examples of men who encounter death in different but at the same time similar ways. The first are "wise men", perhaps philosophers. They know that "dark is right" because they know what to look for at the end of life. Despite their wisdom, however, "they do not go meek" because their words "had not forked the lightning." This phrase has the force of a symbol suggesting that the wise men lacked the ultimate power of nature. Thomas thus seems to be saying that the wise men were not wise enough, that their words created not an ultimate linguistic reality but a vague speculation about death as a good thing. Subsequently the good men of the third tercet let their lives slip away. The festive image of “bright/Their frail deeds might have danced in a green bay” evokes a wondrous world of joyful activity contrasted with “frail deeds.” Why, we ask, do good men long for the past just as the last wave passes? As for the style, it is definitely an elevated style of poetic diction within a villanelle format. The term originates in Italy (Italian villanella from villano: "peasant"); and later used in France to designate a short poem of a popular character favored by poets of the late 16th century. Five tercets are followed by a quatrain, with the first and last lines of the stanza alternately repeated as the last line of subsequent stanzas and collected in a couplet at the end of the quatrain. The verse is repeated for dramatic effect and tone: Anger, anger against the dying of the light. In this case this particular stanza, drawing much of its impact from repetition and variation, paints a clear and defined picture of the author's strong emotions. And all this in just two rhymes. Thomas further aggravates his.
