Two Lives of Charlemagne

Einhard was born of noble parents in the Main valley around A.D. 770. He became a friend of Charlemagne and his family, and was chosen to invite Charlemagne to crown his son as his successor in 813. After Charlemagne's death he was a loyal servant of Louis the Pious, and he died in 840.

Notker the Stammerer (A.D. 840-912), also called Notker I, Notker the Poet or Notker of Saint Gall, was a musician, author, poet, and Benedictine monk at the Abbey of Saint Gall in modern Switzerland.
