Toponymic surnames and the spatiality of heresy prosecutions: Peter Seila’s register of sentences from the Quercy region (Languedoc), 1241–1242

Abstract

AbstractOur knowledge of the geography of medieval religious dissent and its repression in the Latin West is limited by a lack of systematic study of locational information in inquisition trial records. Spatial analysis of these rich details has the potential to help build a bottom-up picture of interaction between dissidents and inquisitors that moves beyond institutional perspectives. This task is rendered challenging due to the inconsistencies and uncertainties of what inquisitors and their notaries typically recorded about the spatial associations of suspects. Probably the most common indicator of such associations found in inquisition records are toponymic surnames. They present challenges of coverage (not everybody had a toponymic surname) and interpretation (multiple possible meanings). This study attempts to tackle the challenge of interpreting such surnames within the context of the nine sentencing events held by the inquisitor Peter Seila in 1241 and 1242 in the Quercy region of Languedoc: covering 650 sentenced individuals, the register documenting these events is the earliest extant record of an inquisition of such scale. Rather than taking the interpretative challenges of toponymic surnames as reasons to limit ourselves to qualitative analysis, our approach shows the value of rendering and analysing them as structured data. Firstly, we quantify the context of toponymic surnames, placing them against the background of broader name construction practices and other social factors. Secondly, we plot and analyse the geocoded data derived from toponymic surnames with the benefit of this contextualisation, looking especially at the distance of toponyms from their associated sentencing centres, in order to derive narratives that best explain the generality of their meaning. The results allow us to appraise the actual spatial coverage of the nine sentencing events. The first two, centred on the important towns of Montauban and Moissac, seem most likely to have been primarily urban affairs, with little evidence of rural coverage. The remainder, which took place in castra (fortified villages), appear to have covered more of the surrounding countryside. These results geographically contextualise the reports of dissidence conveyed within Peter’s register, and suggest narratives for how Peter optimised his strategy for impact in the face of constraints.
