Chartularium Sangallense. Band II (841–999), bearbeitet von Peter Erhart unter Mitwirkung von Karl Heidecker, Rafael Wagner und Bernhard Zeller. Chartularium Sangallense, 2. St. Gallen: Stiftsarchiv St. Gallen, 2021, 597 pp., large-format map.

St. Gall was one of the central monasteries of European Christendom during the Middle Ages. Its holdings also form a fundamental research basis for peripheral regions such as Ireland. In particular, the charters that have been recorded offer a wide range of access possibilities, which, as with the numerous rulers’ charters, extend far beyond the direct environment of the monastery. How large this direct sphere of influence of the monastery was becomes clear from a large-format map, which is enclosed with the book of charters to be discussed here, and which topographically locates all the places mentioned in the charters. In total, more than 1000 places (!) are identified and located, which will be invaluable for all future research, not only on St. Gall, because only this long-needed tool shows the monastic relationship to space.
