Sources and Tradition
Gregory of Tours records that Dionysius was bishop of the Parisii and was put to death by beheading with a sword. The earliest detailed narrative of the martyrdom, the Passio SS. Dionysii Rustici et Eleutherii, dates from about the year 600.
Dionysius is the most widely known cephalophore, or head-carrying saint, in Christian tradition. A later legendary account relates that after his decapitation he took up his own head and walked some distance while preaching a sermon on repentance. The orthodoxwiki account also credits him with carrying the faith furthest of the Roman missionaries in Gaul and with establishing sees at Paris, Chartres, Senlis, and Meaux.
