The metaphors in William Blake’s poem, “The Tyger," emphasize the shape of the revolution, the creator of the revolution and the backstage reason why people need revolution. In line 1 and 2 the metaphor “burning bright, forests of the night” compares the tyger to the burning bright in the dark forests in order to suggest that the burning bright, which stands for revolution power is conquering the dark forests, which represents the forces of evil. “On what wings dare he aspire? What the hand, dare seize the fire?”(Line 7 8) From the second stanza, Blake depicts a picture of how difficult of looking for the fire to “make” the eyes of tiger. Here the fire is the fire (symbol) of revolution, what the meaning behind this is that William is trying to say that only if we could get through innumerable trials and hardships can we find the truth of revolution. In the third stanza, William states that “ what shoulder, and what art, could twist the sinews of the heart”(Line 9, 10). The “shoulder” and “art” imply the creator of the tiger’s “heart”. Is the creator God? No it’s not. The creator is the insurgent force. Because of the insurgent force as the creator, then the heart of revolution (tiger’s heart) can grow up. Once it begins to “beat” (11), it will take control of the “dread hand” and “dread feet”(12). Here shows that with the development of the heart of revolution, thousands of gladiators are willing to participate in the revolution. This situation, obviously, is indeed dreadful. Consequently, “dread hand” and “dread feet”(12) represent the power, which more specifically is the fighters of revolution. When we have the fire of revolution, heart of revolution and the fighters of revolution, now we need the brain of revolution to guide us. The “thy brain”(14) is the metaphor of the brain of revolution. According to this stanza, “hammer and chain”(13) provide us with an image
