" In what distant deeps or skies Burnt the fire of thine eyes? On what wings dare he aspire? What the hand dare seize the fire? And what shoulder and what art Could twist the sinews of thy heart? And, when thy heart began to beat, What dread hand and what dread feet? What the hammer? what the chain? In what furnace was thy brain? What the anvil? what dread grasp Dare its deadly terrors clasp?
