 Abbess Gisela was the one person to send Alcuin the news at Tours of her brother Charlemagne’s official coronation.Nelson suggests that the abbess, as well as writing to Alcuin in Latin to request a Biblical commentary, was responsible for writing the "Annales Mettenses priores", which recorded a visit from the Holy Roman Emperor Charlemagne himself in 804.By the 9th century, the nuns of Chelles were renowned as skilled copyists and authors of manuscripts.
