There was a giant who lived on Lotterberg called Lothar. Because the giant Kunibert had stole Lothar's beloved, the giantess Nagathe, and tried to take her back to Heiligenberg (a nearby hill), Lothar threw a huge block of stone at him. The throw went wrong and the stone landed in the field next to the Eder river, where it can still be seen today as the Riesenstein, close to Wolfershausen.
