Iamblichus of Trier

Iamblichus of Trier (also Jamblichus) was bishop of Trier, attested from 475-476. He is known from a funerary inscription found at Saint-⁠Germain-⁠du-⁠Plain near Chalon-⁠sur-⁠Saône, which scholars consider beyond doubt to be that of the bishop of Trier. His Greek name was put down to a Greek-⁠Oriental colony that remained in the city, but others think the bishops came from the Rhone valley.

Bishop Auspicius of Toul, in a verse epistle, urges the Frankish count Arbogast, master of the Trier region, to treat the bishop with respect. Iamblichus had ties with other bishops of northern Gaul, among them Lupus of Troyes and Sidonius Apollinaris. In his time the first signs appear of the subordination of other sees, such as Troyes, to Trier. He is venerated as a saint in the West, from the time of the undivided Church.
