Quirinus of Tivoli

Saint Quirinus of Tivoli is honoured as a martyr at Rome and at Tivoli, the city where the centre of his cult lies. No sure historical account of him survives, and according to the Bibliotheca Sanctorum his relics rested in the basilica of San Lorenzo at Tivoli.

Some scholars take him to be the same person as Bishop Quirinus of Siscia, whose relics were carried from Pannonia to Rome and perhaps to Tivoli at the time of the Hun invasions, which would explain how a cult arose at Tivoli. Cardinal Cesare Baronio entered his name in the Roman Martyrology under 4 June, and the Hieronymian Martyrology mentions on the same day a Quirinus, with the name of the city Nividunum.

Quirinus of Tivoli is commemorated on 4 June as a saint of the West before the Great Schism (a saint of the undivided Church), by the New Calendar.
