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.

Lollards, 1414–1522

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.

Religious houses in Czech lands

This interactive map application presents the most complete available digital data set of Christian religious houses in the Czech lands from the beginnings up to the present day. The data were manually compiled on the basis of the extensive, so far nine-volume encyclopedia by Milan Buben, Encyklopedie řádů, kongregací a řeholních společností katolické církve v českých zemích.

The map covers 782 records and thus represents a very comprehensive resource on the development of Christian monastic life in the Czech lands. However, a crucial gap is the absence of female religious houses, because the volume on those has not yet been published. Female houses are thus covered only insofar as they were described as part of a record in the hitherto published volumes.

Heresy cases in the West, c.1000-c.1150

This interactive map application presents the most complete dataset of early cases of heresy in the West, ca. 1000–1150, compiled from original Latin sources. It shows locations, heresy cases linked to those locations, and mentions in the sources, on which the description is based. The application allows filtering by time, religious aspects (beliefs and practices), and intervention (type of action against heresy, outcome of the case).

Data source: close reading of original sources
Type of primary source: chronicles, letters, charters, theological treatises, synodal acts, annals, vitae, books of miracles,
exegetical commentaries, etc.

Bibliographies

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.
