During rescue excavations carried out near the vicus at Kempraten (municipality of Rapperswil-Jona, St. Gallen, Switzerland) in advance of a private construction project, a Mithraeum measuring approximately 8 by 10 m was unexpectedly discovered in the summer of 2015 and subsequently excavated and investigated in detail. This paper presents the preliminary results of the excavation, which was completed less than a year ago, and pays particular attention to the interdisciplinary approach used in the excavation. These included intense sampling of the features for the purposes of micromorphology and archaeobiology. Three construction phases with intermittent conflagrations were identified. The question as to whether there was an ante-chamber remains unanswered. The external areas are also quite difficult to interpret, at least for the time being. The rich assemblage of finds, which included numerous coins, pottery, animal bones and a range of religious artefacts (e.g. altars and a half relief), will only be dealt with in a cursory manner here. According to the range of coins, the Mithraeum undoubtedly dated from the late 3rd to the late 4th or early 5th centuries. The site will be analysed by an interdisciplinary team and preliminary work is already underway.
During rescue excavations between 2009 and 2013 carried out at the periphery of the vicus at Kempraten (municipality of Rapperswil-Jona, St. Gallen, Switzerland) a Gallo-Roman sanctuary, dating from the second quarter of the 2nd to the end of the 3rd century AD, was unearthed. The excavation included intense sampling for geoarchaeology and archaeobiology, which prompted the Archaeology Department of Canton St. Gall (KASG) to launch an interdisciplinary project. Four curse tablets attest to the cult of Magna Mater in the sanctuary at Kempraten.
This paper presents the first results of the interdisciplinary study and compares them to the Magna Mater sanctuary at Mainz (Germany), focusing on 1. the layout of the sanctuary, 2. sacrificing, 3. feastings and 4. cursing. The comparison between both sites showed that there was no strict setting of rituals in the cult of Magna Mater, but the importance of cursing and of burnt sacrifices is characteristic for both sites. Summing up: The temple precinct at Kempraten had a specific setting, which showed on one hand local and regional influences, for instance in terms of the temple architecture and the choice of food offerings. On the other hand, distinct differences between the Kempraten sanctuary and local Gallo-Roman sanctuaries can be observed, for instance in relation to cursing, the composition and the importance of the burnt offerings.
