I don’t think I could have done it in cold blood. It was a hundred times more difficult than getting up.

Halfway down I slipped, but, by the blessing of God, I landed, torn and bleeding, upon the path. I took to my heels, did ten miles over the mountains in the darkness, and a week later I found myself in Florence, with the certainty that no one in the world knew what had become of me.
