The edition combines the texts by Der Marner, in his time a highly regarded representative of early Sangspruch poetry, translated and exhaustively commentated, with all documents referring to him and all the texts by 14th to 16th century poets - mostly anonymous - who composed new songs using his melodies and his verses with their own additions. Using this prominent example of a significant part of medieval song composition up to the Reformation, the edition enables the reader to follow poetic processes, literary interests and cultural developments.
