Several thousands of manuscript fragments from medieval Sweden have been discoveredand registered in the research project Medeltida Pergamentsomslag, but thevast majority of these contain liturgical texts in Latin. Here I will present a newlydiscovered fragment of a text in Old Swedish, currently in a private collection inSweden. Three parchment leaves from a manuscript copy of the Old Swedish translationof Pseudo-Bonaventure’s Meditationes Vitae Christi survive pasted onto theinside of a small wooden chest. This text in this translation is only known fromthree other manuscripts, all of which derive from Vadstena Abbey. In what followsI will present the textual tradition as well as the physical context of the survival ofthe leaves. The article also includes a critical edition of the text.
