Heinrich HeineThe stones here speak to me, and I know their mute language. Also, they seem deeply to feel what I think. So a broken column of the old Roman times, an old tower of Lombardy, a weather- beaten Gothic piece of a pillar understands me well. But I am a ruin myself, wandering among ruins.
Heinrich Heine
