Indeed, the theme of release from imprisonment runs like a thread throughout the story: Lúthien's escape from Doriath, her release from Nargothrond with the aid of Huan, Beren's release from Gaurhoth Isle. In every instance it is love that is the liberating factor: Lúthien's love for Beren drives her on to find some escape from imprisonment by her father, Huan's love for Lúthien is what frees her from Nargothrond, Beren's rescue by Lúthien. One could hazard an interpretation of the title as being suggestive of the immense power of love.
