Catholic historians are reluctant to ascribe any pre-Christian antecedents to the dancing procession, and claim only that its origin cannot be stated with certainty. There might be elements of pagan cult, such as the ones that were criticised by Saint Eligius in the 7th century. Documents of the fifteenth century speak of it as a long-established custom at that time, and a similar "dancing" procession, which used to take place in the small town of Prüm, in the Eifel, was documented as early as 1342. Legends are told that relate the dancing procession to an averted plague or offer a fable about a condemned fiddler, but the dancing procession to the saint's tomb is an annual ceremony done as an act of penance on behalf of afflicted relations and especially in order to avert epilepsy, Saint Vitus Dance, or convulsions.
