A manuscript of a variant of the Ystoria, written by Minorite friar C. de Bridia, perhaps based on Joannes's lectures, appeared on the art market in the 1950s and was purchased for Yale University.

The manuscript is perhaps most known because it was bound with a manuscript of Vincent of Beauvais' popular encyclopedia Speculum historiale and a spurious map on vellum, the notorious "Vinland map"- no such map is included with a second, older Hystoria/Speculum manuscript volume found more recently.
