This section features some interactive and static maps presenting data collected or transferred into digital form within the DISSINET project or a partly related project “GIS for the History of Christianity”. We are interested in the places of dissident activities and places of origin or residence of people suspected of heresy as well as in the spatial distribution of the official Church infrastructure and of medieval religious communities displaying some similarities or historical links to dissident religious cultures.
Houses of heretics: Cathar religious houses in Languedoc, 1175–1244
This interactive map shows settlements in Languedoc in which Cathar religious are attested to have dwelt publicly in houses they owned or rented. The period covered ranges from the oldest memory going as far back as 1175 up until the fall of the castrum of Montségur in 1244. The dataset on which the map is based constitutes the most extensive list of settlements with “houses of heretics” in Languedoc available to date.
Data sources: Toulouse, Bibliothèque municipale, ms. 609 (edition by Evans & Sherwood, n.d.; Duvernoy, 2002; Rehr, 2019); Duvernoy, 1976: 231-232; Roche, 2005.

Map by Adam Mertel.
This interactive map is based on the Lollard trials. It shows the places of origin of English dissidents under investigation for taking part in the revolts of 1414 or 1431, related to Lollardy, or holding various heretical opinions that are commonly referred to as Lollard. In addition, it shows in which of these places the owners of unauthorised English religious books were uncovered. A total of 260 sites were transferred from the Atlas zur Kirchengeschichte by Jedin et al., based on the research of J. A. F. Thomson and J. Fines. The plotted sites indicate only the presence of suspected Lollards and revolt participants, not their numbers or importance.

Christian baptisteries, 3rd–12th centuries
This interactive map visualizes a dataset of Christian baptisteries built between the 3rd and 12th centuries. The dataset represents a digital adaptation and formalization of the most complete catalogue of baptisteries by Sebastian Ristow. Of all 1067 buildings in Ristow’s catalogue, this map takes into account only those whose existence and function as baptisteries is considered certain or very probable by Ristow and which, at the same time, could be localised.
The DISSINET team maintains a publicly accessible collaborative bibliography in Zotero. You can either browse the bibliography online or, if you use Zotero, go to Zotero website, find the group “Dissident Networks Project”, join the group, and use the bibliographic records directly in Zotero desktop application (browse, search, copy, expand, reorganize, etc.). The main areas covered are social network analysis, historical network research, digital humanities, historical GIS, and medieval heresy, inquisition, society, economy and demography. We plan to gradually enrich this Zotero bibliography with records from David’s older textual bibliographies concerning the inquisition and various medieval dissident cultures.
Historical Geocoding Assistant
The “Historical Geocoding Assistant” is an open-sourced browser-based application for assigning geographic coordinates in a more convenient and faster way than copy-pasting them from services such as Google Maps. The application was designed with historical projects in mind but is suitable for any geocoding work. Essential features:
- works online with a live Google Spreadsheets table;
- gathers suggestions of coordinates from gazetteers for instant use (GeoNames, Wikipedia, Getty Thesaurus of Geographic Names, Pleiades, and China Historical GIS);
- integrates search services (Google Maps, Google Search, Peripleo);
- supports multiple base layers (OpenStreetMap, satellite images, Imperium, etc.);
- supports multiple overlay layers;
- allows setting relevant spatial extent;
- allows spatial uncertainty levels.
