Digital Atlas of Dioceses and Ecclesiastical Provinces in Late Medieval Europe (1200-1500)
Among the novel features of the Corpus Synodalium database is the ability to visualize search results spatially via the newDigital Atlas of Dioceses and Ecclesiastical Provinces in Late Medieval Europe (1200-1500), for which Rowan Dorin served as the General Editor and Clara Romani served as Co-Editor and Lead Developer. The Digital Atlas was generated from 2016-2021 in tandem with the Corpus Synodalium project, with Thawsitt Naing responsible for integrating the atlas and database via the custom-designed online mapping tool.
Rather than corresponding to any particular year, the boundaries used in this mapping tool represent an amalgam of all Latin dioceses and ecclesiastical provinces that existed at some point during the period 1200-1500. The map excludes jurisdictions in the Latin East and in parts of eastern Europe whose boundaries are unknown (or were never established).
