The anonymous Saxon poet known as Poeta Saxo, who composed the medieval Latin Annales de gestis Caroli magni imperatoris libri quinque ("Annals of the Deeds of Emperor Charlemagne in Five Books") was probably a monk of Sankt Gallen or possibly Corvey. His Annales is one of the earliest poetic treatments of annalistic material and one of the earliest historical works to concentrate on Saxony. It is considered characteristic of the dénouement of the Carolingian Renaissance.
