Venusberg
Venusberg is a motif of European folklore rendered in various legends and epics since the Late Middle Ages.
It is a variant of the folktale topos of "a mortal man seduced by the fairy queen visits the otherworld". In German folklore of the 16th century, the narrative becomes associated with the minnesinger Tannhäuser who becomes obsessed with worshipping the goddess Venus.
