In December 1798, Novalis became engaged for the second time. His fiancée was Julie von Charpentier, a daughter of Johann Friedrich Wilhelm Toussaint von Charpentier, the chair of mining studies at the University of Leipzig. Unlike his relationship with Sophie, Novalis's affection for Julie developed more gradually. He initially saw his affection for Julie as a more "earthly" passion compared to his "heavenly" passion for Sophie, though he gradually softened this distinction with time. Eventually his feelings for Julie became the subject of some of his poetry, including the "Spiritual Songs" written in the last years of his life. Novalis and Julie remained engaged until Novalis's death in 1801, and she tended him during his final illness.
