Marus

Saint Marus, hierarch, was bishop of Trier in the 5th century, around 480-490, one of the first bishops after the end of Roman rule. The period of his episcopate is not known precisely. He is venerated as a saint in the Western Church.

He is said to have restored the damaged church of Saint Mary, later called Saint Paulinus, and to have given the church its dedication to the Mother of God. This work shows that the Church of Trier was beginning to recover from the troubled time at the start of Frankish rule. He was buried there; his tomb lay in the choir of the south aisle of the old Romanesque church, and an altar in his honor was consecrated in 1148. His earliest image is in the Egbert Psalter of the 10th century, and his veneration is attested from the same century.
