The main outlines of the story of the textual transmission of Quintilian's Institutio have long been clear and well known. A series of French manuscripts, dating from the ninth century on, present a mutilated text in which perhaps a third of the whole work is missing. One such manuscript, the Bambergensis, was taken from France in the tenth century and supplemented from a separate unmutilated stream that is also available to us in a ninth-century Ambrosian manuscript, now itself unfortunately damaged.

The Bamberg manuscript generated in the following centuries further complete texts, but all these, as well as their earlier relations A and Bg, escaped scholarly detection in the fourteenth century: Petrarch and his contemporaries had to make do with mutili of the French type.
