Embedded in a dynamic manuscript culture, the medieval book was a cultural artefact that enabled dynamic textuality.1 Because we never deal with a stable text in a manuscript culture, each text witness is equally important for a study which looks at transmission history. The dynamic and adaptable nature of texts can be seen in the transmission of the botte and the so-called Trutta-legend. Therefore detailed analyses, not only of the individual manuscripts but also of their interconnections, are necessary in order to understand medieval texts. My approach uses a combination of Material Philology, involving ‘an ensemble of practices and methods for the study of medieval culture broadly conceived’,2 and Überlieferungsgeschichte, which takes the full codicological production as well as the reception contexts into account.3 This combined approach allows the manuscripts to be placed into their historical backgrounds, and to understand the transmitted texts within larger cultural contexts.4 Special consideration is given to the relationship between the materiality of the texts’ transmission and the devotional piety they evoked.
