The face of the angel of history is turned toward the past. Where we perceived a chain of events, he sees a single catastrophe which keeps piling wreckage and hurls it in front of his feet. The angel would like to stay, awaken the dead, and make whole what has been smashed. But a storm is blowing from Paradise; it has got caught in his wings with such violence that the angel can no longer close them. This storm irresistably propels him into the future to which his back is turned, while the pile of debris before him grows skyward. The storm is what we call progress.
