 The "Poeta Saxo", an anonymous Saxon poet who composed the "Annales de gestis Caroli magni imperatoris libri quinque" ("Annals of the Deeds of Emperor Charlemagne in Five Books") near the end of the 9th century, relies heavily on classical models and existing sources like Einhard and the Royal Frankish Annals.Generally, he offers an interesting literary restatement of the older vitae and annals, but little new history.Not surprisingly, many modern historians dismiss the historical accuracy of Notker the Stammerer's account.
