Denis of Paris was a 3rd-century Christian martyr and saint. According to his hagiographies, he was bishop of Paris in the third century and, together with his companions Rusticus and Eleutherius, was martyred for his faith by decapitation. Some accounts placed this during Domitian's persecution and incorrectly identified St Denis of Paris with the Areopagite who was converted by Paul the Apostle and who served as the first bishop of Athens. Assuming Denis's historicity, it is now considered more likely that he suffered under the persecution of the emperor Decius shortly after AD 250.

Although the main focus of his cultus was in the small village of Brioude, he was originally from the city of Vienne, and also associated with Clermont.

Gregory wrote a vita of Julian, but his attempts to expand the saint's cult from the Auvergne to Touraine and Aquitaine were unsuccessful, and Julian is now only remembered through his basilica in the town of Brioude itself.
