All attempts to interpret Hagen's name or home are highly speculative. Although the "Nibelungenlied" has a historic center, it was written down only centuries later, in 1200, and therefore incorporated the author's Medieval knowledge and intentions. There are suggestions that the epithet refers to more or less similar-sounding place names. However, names that have only a phonetic similarity but no meaningful link with the legend are rejected by scholars, since it is very likely that such connections are random and add nothing to the interpretation of the character. It is believed that the poet of the "Nibelungenlied" accepted Tronje as a real place name in the Burgundian kingdom; but it is questionable that he himself knew its exact location, since the story's many geographical mistakes suggest that his knowledge of the area around Worms was not particularly good.
