From August 1800, Novalis began to cough up blood. At the time, he was diagnosed with tuberculosis. However, recent research suggests that he may have suffered from cystic fibrosis, a genetic disorder that may have been responsible for the early death of many of his siblings, including his brother Erasmus. After a severe hemorrhage in November, he was temporarily moved to Dresden for medical reasons. In January, he requested to be with his parents in Weissenfels. He died there on March 25 1801 at the age of twenty-eight. He was buried in Weissenfels's "Alter Friedhof" ("Old Cemetery").
