anecdotes regarding the Emperor Charlemagne, is now commonly believed to be Notker the Stammerer. This monk is known from his work to have been a native German-speaker, deriving from the Thurgau, only a few miles from the Abbey of Saint Gall; the region is also close to where Notker is believed to have derived from. The monk himself relates that he was raised by Adalbert, a former soldier who had fought against the Saxons, the Avars ("Huns" in his text) and the Slavs under the command of Kerold, brother of Hildegard, Charlemagne's second wife; he was also a friend of Adalbert's son, Werinbert, another monk at Saint Gall, who died as the book was in progress. His teacher was Grimald von Weißenburg, the Abbot of Saint Gall from 841 to 872, who was, the monk claims, himself a pupil of Alcuin. The monk's untitled work, referred to by modern scholars as De Carolo Magno ("Concerning Charles the Great") or Gesta Caroli Magni ("The Deeds of Charles the Great"), is not a biography but consists instead of two books of anecdotes relating chiefly to the Emperor Charlemagne and his family, whose virtues are insistently invoked. It was written for Charles the Fat, great-grandson of Charlemagne, who visited Saint Gall in 883. It has been scorned by traditional historians, who refer to the Monk as one who "took pleasure in amusing anecdotes and witty tales, but who was ill-informed about the true march of historical events", and describe the work itself as a "mass of legend, saga, invention and reckless blundering": historical figures are claimed as living when in fact dead; claims are attributed to false sources (in one instance, the Monk claims that "to this King Pepin [the Short] the learned Bede has devoted almost an entire book of his Ecclesiastical History"; no such account exists in Bede's history – unsurprisingly, given that Bede died in 735 during the reign of Charlemagne's grandfather Charles Martel); and Saint Gall is frequently referenced as a location in anecdotes, regardless of historical verisimilitude (Pepin the Hunchback, for example, is supposed to have been sent to Saint Gall as punishment for his rebellion, and – in a trope owed to Livy's tale of Tarquin and the poppies – earns a promotion to rich Prüm Abbey after advising Charlemagne through an implicit parable of hoeing thistles to execute another group of rebels).
