The one-eyed singer, songwriter, and knight errant Oswald von Wolkenstein (surname literally Cloud-Stone ) was among the last of the great troubadours. A contemporary of Villon, versed in Petrarch, and a Knight of the Holy Sepulchre, Wolkenstein was lost to history until scholarship in the 1970s recognized him as the German language’s first genuinely autobiographical lyric voice. In the hands of the magician-translator Richard Sieburth, working in the spirited tradition of Ezra Pound and Paul Blackburn, Wolkenstein’s verse rises from the page like a medieval Bob Dylan. Facsimiles of Wolkenstein’s musical compositions are included.
