Aprunculus of Treves

Saint Aprunculus of Trier (also known as Abrunculus) (died probably 526) was Bishop of Trier from the death of his predecessor, Fibicius, around 525, He served in that capacity until his own death in 526, and was succeeded by Nicetius.

Aprunculus is venerated as a saint; his feast day at Trier is 22 April. His relics are preserved at Springiersbach Abbey. He is the patron saint of Bruchsal in Baden-Württemberg.

Life Aprunculus may have belonged either to the disempowered pre-Frankish clergy of Trier or to the clergy sent to Trier from Auvergne by Theuderic I. There is a widespread story that Saint Gall was active in Trier at the same time as Aprunculus but this is unhistorical, as Gallus lived a century later, and likely confuses Saint Gall with Gallus of Clermont. The absence of information on the bishops of Trier in the late 5th and early 6th centuries in contemporary sources suggests that the church in Trier was not significant politically in this period.

Veneration Aprunculus was probably buried in a small oratory on the site of St. Symphorian's Abbey in Trier. Since the end of the 6th century he has been venerated as a saint. He is recorded in the Martyrologium Hieronymianum. Gregory of Tours mentions him.

There are reports of his veneration in Trier from the 10th century onwards, and also in Auxerre, Autun and Gellone in Languedoc. A portrait of him is found in the Egbert Psalter.

In 1047 his remains were transferred to St. Paulinus' Church, Trier, and Itzig (in Luxembourg).

His feast day is 22 April, which is likely the date of burial rather than his date of death.
