The pseudo-Augustinian S. App. 121 and its medieval textual connections: A testcase for the development of network visualizations in the PASSIM Research Tool

This article investigates the benefits and challenges inherent in using networks to visualize and analyze the textual connections between Latin patristic sermons as transmitted in medieval manuscripts. Patristic sermons, which had a dynamic reception in the Middle Ages and were the subject of an extensive and complex scholarly tradition, are an ideal test case for an inquiry into the manipulations of texts as part of the process of textual transmission in the Middle Ages. Using the pseudo-Augustinian sermo 121 as a case study, we will first describe the textual history of the sermon. Subsequently, we will translate this narrative of the scholarly history of PS-AU s 121 into network visualizations of increasing complexity and reflect on the accuracy, usefulness, and challenges of this method for the study of the myriad textual connections between patristic sermons in medieval contexts. This case study on network visualizations is part of a larger project to develop a digital application and database, the PASSIM Research Tool, to chart the dissemination and manipulation of patristic preaching in the Middle Ages.
