The re-discovery of medieval Germanic poetry, including Gottfried von Strassburg's version of , the "Nibelungenlied" and Wolfram von Eschenbach's "Parzival", left a large impact on the German Romantic movements during the mid-19th century. The story of Tristan and Isolde is a quintessential romance of the Middle Ages and the Renaissance. Several versions of the story exist, the earliest dating to the middle of the 12th century. Gottfried's version, part of the "courtly" branch of the legend, had a huge influence on later German literature.
