Domninus of Grenoble

Holy Hierarch Domninus of Grenoble was the first known bishop of Grenoble in Gaul, in the 4th century, and reposed in 384 or 386. He is venerated as a saint in the Orthodox and Roman Churches. He is a saint of the undivided Church.

He became bishop by appointment of the emperor Gratian, at the time when the village of Cularo was renamed Gratianopolis, that is, Grenoble. In 381 he took part in the council of Aquileia, which condemned Arianism. He was probably buried in the first mausolea on the site of the later church of Saint-⁠Laurent, though there is no longer evidence of this. The Orthodox calendar commemorates him on 5 November.

He is commemorated on 5 November, the liturgical date in the Orthodox calendar (the same day number on the old and new calendars).
