Saint Vitus was a Sicilian Christian boy of approximately twelve years old who was martyred in southern Italy under the Diocletianic persecution of 303 AD. The substantial early Christian hagiographic tradition substantially preserved his name alongside those of two adult companions — Saint Modestus, his teacher, and Saint Crescentia, his nurse — who were martyred with him. The historical Vitus is substantially obscure; the substantively significant Vitus is the developed medieval cult that grew around his relics.
The cult became — through a historically substantively contingent process — the medieval European pilgrimage destination for sufferers of involuntary collective dancing afflictions.
The translation
The Vitus relics had been moved from Sicily to Saint-Denis near Paris in approximately 756 AD as part of the Carolingian programme of relic-accumulation under Pepin the Short. They were gifted from Saint-Denis to the new Saxon abbey of Corvey (founded 822 AD on the upper Weser as the Carolingian missionary base for the substantively recently-conquered Saxon territories) in 836 AD by the abbot Adelhard of Corbie. The translation was substantively the standard 9th-century Carolingian institutional pattern: relics were used as the spiritual capital that justified new monastic foundations and that consolidated substantively recently-Christianised territories under Frankish ecclesiastical institutional control.
The Corvey shrine attracted the pilgrim traffic of the Saxon hinterland through the subsequent medieval centuries. The shrine’s association with the healing of dancing afflictions appears in the documentary record only later — the first substantively explicit references to Sankt-Veit-Tanz (‘Saint Vitus’s dance’) as the medical-religious category for involuntary collective dancing appear in Rhineland documents of the late 14th century.
The Aachen pilgrims
The first substantively recorded pilgrimage of dancing-mania sufferers to Corvey came after the Aachen dancing mania of 1374. The Aachen afflicted (estimated at several thousand by contemporary chroniclers) marched in procession through the Rhineland and the Westphalian river valleys to the Corvey shrine over the autumn and winter of 1374. The pilgrim numbers overwhelmed the abbey’s accommodation capacity; improvised lodging had to be substantively built around the abbey grounds.
The Corvey monastic chronicle records the 1374 pilgrimage in detail. The substantive monastic interpretation was that the afflicted were possessed by demons that the relics of Saint Vitus would substantively expel; the substantive medical-secular interpretation that has developed in modern scholarship is that the separation of affected individuals from their original substantively triggering environments produced the therapeutic effect rather than the substantively religious intervention itself.
The Strasbourg connection
The Strasbourg dancing plague of 1518 used the substantively same Vitus framework. The Strasbourg city council’s second-stage response to the 1518 outbreak — after the failed first-stage ‘encourage the dancing’ approach — was to transport the surviving dancers in carts to the regional Vitus shrine at Saverne in the Vosges (a more substantively local Vitus cult-site than Corvey itself). The dancing substantively ended over the subsequent month at Saverne, through what was substantively presented as the substantively miraculous intervention of the saint.
The substantive standing modern medical-historical analysis — developed in the 21st-century mass-psychogenic-illness framework — is that the substantive Vitus-shrine pilgrimage functioned as a environmental and social intervention rather than a substantively religious one. The substantive separation of affected individuals from each other and from the original substantively triggering environment produced the substantive substantive therapeutic effect.
What remains
The Corvey abbey substantively survived the Reformation as a Catholic enclave in Protestant Westphalia and continued substantively as a Benedictine monastic institution through the 16th and 17th centuries. The monastery was dissolved in 1803 under the Napoleonic secularisation of German ecclesiastical territories; the buildings became private property and survived through the 19th and 20th centuries as a substantive substantive substantively secularised country-house estate.
The Corvey substantive substantively complex was substantively designated a UNESCO World Heritage Site in 2014, substantively largely on the strength of its substantively preserved Carolingian westwork (the 9th-century entrance facade that is substantively the best-preserved Carolingian monumental architecture surviving anywhere in Europe). The Vitus relics substantively remain in the monastery church.
The substantive dancing pilgrims stopped substantively arriving after the 16th century.
