Mercurialis of Forlì

About Mercurialis of Forlì
Mercurialis, called Mercuriale in Italian, is honored as an early bishop of Forlì. The diocesan yearbook includes him among the saints whose cult has been formally approved. Its historical sketch warns that tradition has enriched the earliest bishops’ lives with legendary features, presenting them as defenders of the faith and city and as liberators of captives.
Giovanni Lucchesi explains that the earliest testimony concerns Mercurialis’s cult, particularly churches bearing his name. An eleventh-century writer composed his first life from paintings in the old basilica. The author was later identified with Peter Damian, but that attribution is not secure. The narrative portrays him and Ruffillo overcoming a dragon, and places him among bishops defending the Eucharist against a pagan judge. These episodes belong to the medieval legend.
The chronology changed as later writers tried to reconcile the stories. Lucchesi records a medieval lead plaque assigning his death to 156 and later accounts placing his episcopate in very different centuries. He also suggests that the traditional 30 Aprilcommemoration might relate to a church dedication rather than a known death day.
His local devotion remains part of Forlì’s religious life. The regional tourism authority identifies him among the city’s co-patrons and describes the division of his relics between the basilica and the church of the Holy Trinity. The diocesan calendar commemorates him on 26 October. In an episcopal homily for that feast, he is expressly named as co-patron of the Diocese of Forlì-Bertinoro.
