"All things are signs in nature, still there are Subtle analogies we dimly trace. Perhaps our moral world has but its day, Of which the great sun is the glorious type; And intellect will run its course, and set. If so, we touch on the extremest verge Of our horizon ; and our arts, our power, Our conquests o’er the many realms of mind. Wealth, painting, sciences, and poetry Are but that rich magnificence of hues Which heralds in the closing of our day."
