St. Denis

Denis — Dionysius of Paris — was the first bishop of Paris, a third-century martyr, and one of the more complicated figures in the history of the French church, because his story carries the weight of a persistent historical confusion that took many centuries to untangle. For much of the medieval period, Denis of Paris was identified with Dionysius the Areopagite, the Athenian convert of St. Paul mentioned in Acts 17, and then further with the author of the extraordinary mystical treatises known as the Pseudo-Dionysian corpus — the Celestial Hierarchy, the Divine Names, the Mystical Theology. The problem is clear: these are three distinct persons who were for a long time treated as one, largely because of an identification promoted in Carolingian times that served the interests of the great abbey of Saint-Denis.

The historical Denis of Paris was, most probably, a missionary bishop sent from Rome to Gaul in the mid-third century, in the same wave of missionaries that evangelized other regions of Gaul — Saturninus to Toulouse, Martial to Limoges. He was martyred, with his companions Rusticus and Eleutherius, probably under the Decian or Valerian persecution. He died on the hill outside the city that subsequently bore the name Montmartre — the Martyr's Hill. The tradition records that he was beheaded there and that he then carried his own head to the site, two miles to the north, where the great basilica of Saint-Denis was later built over his burial place.

The cephalophore tradition — the saint who carries his own severed head — is worth examining with appropriate mixture of interest and caution. As biography it is impossible; as an expression of something about the place of burial and its relation to the place of death, it is the kind of tradition that cannot simply be discarded. The abbey of Saint-Denis, built over his tomb, became the burial church of the kings of France. The martyr bishop whose real biography is so sparse is encased in one of the great ecclesiastical monuments of the medieval world.
