This is a working transcription of the inquisition register of John Galand (Jean Galand) and William of Saint-Seine (Guillaume de Saint-Seine), 1283-1302 (Paris, Bibliothèque nationale de France, fonds Doat, vol. 26, fol. 79r-316v). The text we publish here should not be considered a critical edition, but facilitates access to a valuable early inquisition register, and does that in a digital and reusable form (see licence). We appreciate suggestions for corrections wherever you spot errors. The format is plain text, without critical apparatus or other editorial markup. It can thus be directly used - besides human reading - for computational text analysis. The individual records are separated with three empty paragraphs, thus allowing to work with the text segmented into meaningful parts. The transcriptions were done by Daniela Wallnerová (editor), who holds 95% contribution, and supervised and revised by David Zbíral, who holds 5% contribution. The transcription has received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (grant agreement No. 101000442, project “Networks of Dissent: Computational Modelling of Dissident and Inquisitorial Cultures in Medieval Europe”).
