求威廉·巴特勒·叶芝（WilliamButlerYeats）的作品《拜占庭》原文.?

Byzantium, a poem by William Butler Yeats, depicts a world beyond earthly complexities. The chaos of humanity recedes, leaving behind the serene stillness of night. The speaker beholds an image of a figure, possibly a shade or a ghost, that evokes death-in-life and life-in-death.

The speaker marvels at the supernaturality of this image, calling it a miracle beyond the ordinary. This being can crow like a cock in Hades, or scorn the world in its unchanging metallic glory. It transcends all earthly complexities of blood and mire.

In the glow of midnight flames on the Emperor's pavement, spirits born of blood come together and break free from the complexities of fury. They dance in an agony of trance and flame that cannot harm even a sleeve. As the dolphin-torn sea churns beneath them, the golden smiths of the Emperor craft a new reality, pouring forth fresh images from the chaos of the world.
