The speaker watches men working in a steel mill, surrounded by furnace glow, flowing molten metal, rumbling cranes, and massive hammer blows. The scene is raw, loud, and almost mythic—half-clad workers bend iron and steel to human purpose. At first it feels like pure industrial power. Then the poem turns inward: the speaker senses that just as steel is shaped by heat and force, human souls are shaped through suffering, passion, and time. The “hammer of sin” acts like those heavy hammers on the anvil, beating and forming something within us.
The mood is intense, dark, and awestruck rather than despairing. There is a feeling of grim reverence for both the workers and the hidden process of becoming, as if pain and struggle are not meaningless but part of forging a deeper self.
