Old High German lullaby
The discovery of an Old High German lullaby (Althochdeutsches Schlummerlied) was announced in 1859 by Georg Zappert (1806–1859) of Vienna, a private scholar and collector of medieval literature. Ostensibly a 10th-century poem full of surviving pre-Christian mythology, it is considered a literary forgery of Zappert's by many experts who have commented on it.
