In the Annales Ianuenses, small marginal glosses supplement the text and
engage with the main subjects in the historical narrative, as well as acting as
visual markers. For example, on fol. 72v the description of the judex Petrus of
Cagliari has an ink drawing with the addendum Judex sardine (Fig. 8.1). The

and archbishop of Genoa, as a good vassal to a good and true lord, and from here he held
his judicate for the city of Genoa).”
