Aurelius of Riditio

Saint Aurelius of Riditio was a bishop in Armenia and reposed at Milan on 9 November, around the year 475. Beyond the day of his death almost nothing certain is known of his life; even the city of Riditio has not been located with certainty.

Traces of him are nonetheless found in written sources and inscriptions. The oldest is a copy of a memorial from Milan showing a double tomb in which Aurelius is said to have lain with the Milanese bishop Dionysius; the consular year mentioned there fixed his death in 475. According to Le Quien he was bishop of Ariaratia.

Around 830 to 832 his relics were taken to the Black Forest by Bishop Notingus of Vercelli, to the abbey of Hirsau. They remained there until 1488, then were moved to the new monastery of Saints Peter and Paul. Aurelius is regarded as a patron against diseases of the head. He is commemorated on 9 November, by the Western calendar (new style), as a saint of the undivided Church.
