"Good men, the last wave by, crying how bright their frail deeds might have danced in a green bay, rage, rage against the dying of the light."

     The fundamental idea of this line is that good men will always rage, with all their power, until the very end. The "last wave by" that the poem discusses represents the concept that a generation of good people are approaching their demise. As they reflect on the life that they experienced, they also despair over the actions that they might have done, had they been able to live longer. Figuratively speaking, they cry at how beautifully their "last wave" might have "danced in a green bay" instead of fading away into nothing. The image I selected shows a boat returning to shore, just as the sun is setting. With life being compared to the roaring adventures of a boat at sea, both journeys will end when the shore is reached and the sun is down. Although the "frail deeds" of dying people may never be achieved, they must overcome their weaknesses and persevere until the end.
