Ulrich von Türheim

Ulrich von Türheim (c. 1195 – c. 1250) was a German writer from the Augsburg area writing during the first half of the 13th century. Three of his works have survived: a conclusion to the version of the Tristan legend left unfinished by Gottfried von Strassburg; ''Rennewart'', a continuation of ''Willehalm'', left unfinished by Wolfram von Eschenbach; and fragments of a version of ''Cligès'' based on that of Chrétien de Troyes. It is not known whether this last work was a separate work or also a continuation, in this case of a now lost ''Cligès'' by Konrad Fleck. The relative chronology of these works is disputed, though ''Rennewart'' is generally regarded as the last.

Conrad of Winterstetten was his patron. Provided by Wikipedia
