[1] Vatican 645 contains a copy of Bede's Easter table based on the Metonic cycle down to the year 1025.
In the margins one hand has added the names of the Roman emperors down to Charlemagne (800–14).
Another hand of the ninth century added two brief notices for the years 793 and 844.
In the eleventh century, four more monks added notices in the margins of the Easter table.
Several of the annals are cut off partially or entirely by poor subsequent bookbinding.
