The Queen of Cluse in Der Stricker’s Daniel.
Her husband, King Matur, challenged Arthur and was slain. Arthur then took over Cluse. Danise mourned for Matur but agreed to marry Daniel of the Blossoming Valley, a noble knight of Arthur’s who had made the conquest possible.
M. Resler suggests that Der Stricker chose her name because it corresponds phonetically with ‘Daniel’. Der Stricker may also have derived it from Dyonise of Durmart le Gallois.
