Stay tuned to this research diary to get updates about the activities and events of DISTINGUO, a research programme dedicated to the study of “distinctiones” in medieval Latin preaching (funded by ANR 2019, under the supervision of Marjorie Burghart, CNRS – CIHAM UMR 5648). As key ingredients of Latin sermons from the 12th c. onwards, “distinctiones” have been part of this mass communication phenomenon, and deserve to be properly studied.
