Sources and the Acts
The narrative of Quiricus and Julitta is preserved in passion accounts of differing detail, and the variations in the tradition are long-recognized. In the sixth century a set of Acts circulating under their names was listed among apocryphal writings in the Decretum Gelasianum, and modern accounts accordingly relate the more elaborate episodes as tradition rather than documented history. The essential and consistently transmitted facts are the mother-and-son pairing, the child's confession, and their martyrdom under Diocletian.
Despite the questioned Acts, the cult of the two martyrs spread widely in both East and West. By tradition their relics were discovered in the reign of Constantine the Great; in the East the head of Quiricus is venerated at the Monastery of Grigoriou on Mount Athos, with relics of Julitta kept in monasteries of Greece and Cyprus. In the West their veneration became strong in France, traced to Amator (Amador), Bishop of Auxerre, who was said to have brought relics from the East in the fourth century.
