Siegfried, the hero of the Nibelungenlied, is the Teutonic version of Sigurd, who, in the Volsunga Saga, slew the dragon Fafnir and took his hoard of cursed elfin gold.

The theme of the man fighting against the dragon (St. George became the patron) is one of the most popular of all medieval literatures, and can be found earlier in Beowulf
