Notker, however, adds another element to the story, possibly borrowed from the Roman historian Livy's account of Tarquin's poppies. Some time later, when faced with another revolt, Charlemagne sends messengers to Pepin to ask his advice. The king's men find Pepin weeding nestles in the garden, where he refuses to offer Charles any advice, saying "I will send him no message except—what I am doing! I am digging up the useless weeds in order that the valuable vegetables may be able to develop more freely." When the messengers relate the story back to Charlemagne, he manages to "divine the real meaning of the words" and puts the rebellious nobles to death. As a reward for his good counsel, Charles allows Pepin to choose "the manner of life that most pleased him" and Pepin asks to move to the monastery of Prüm.
