Magnus of Füssen

Our Venerable Father Magnus, Abbot of Füssen, Apostle of the Allgäu

Venerable · d. c. 665 (traditional; scholarship places him in the mid-8th century)

Magnus (Magnoald, Mang) is the apostle of the Allgäu, the Alpine country of south-western Bavaria, and founder of the monastery of Füssen on the river Lech, which bore his name (St Mang) until its dissolution. His Life places him in the circle of the Irish missionaries Columbanus and Gallus and dates his repose about 665 — so the York calendar styles him "disciple of St Columbanus" — though the Life is a ninth-century composition whose chronology is internally contradictory, and scholarship places the historical Magnus in the mid-eighth century. He reposed on September 6, his feast in Germany and in the York calendar alike.

All narrative knowledge of Magnus comes from the Vita Sancti Magni, written at the monastery of Ellwangen about 851, for the translation of the saint's relics in that year; it claims to be the work of Theodore, Magnus's own companion, found barely legible in the saint's tomb — a claim scholarship does not accept (see the disputed questions below). What follows is the Life's account, given as the tradition the calendar transmits.

Magnus and Theodore were clerics living with Willimar, a priest at Arbon on Lake Constance, when Columbanus and Gallus came there on their exile out of Burgundy. When Gallus fell ill and remained behind, Magnus and Theodore were given the care of him, while Columbanus went on over the Alps to found Bobbio. On Columbanus's death Gallus, learning of it by revelation, sent Magnus to pray at his grave; Magnus returned from Bobbio with the staff of St Columbanus, and the community thereafter kept Columbanus's rule — the ground of the calendar's styling of Magnus as the great abbot's disciple. After Gallus's own death, Magnus went east with the priest Tozzo at the request of Wikterp, bishop of Augsburg, to evangelise the eastern Allgäu, then still part-pagan. He crossed the Lech at the place still called St. Mangstritt ("St Magnus's footstep") and built his cell there; around it rose the monastery of Füssen (St Mang), which he governed as abbot until his repose, traditionally on September 6, about 665. The Life clothes his mission in the imagery of dragons slain and demons driven out — the legendary dress, as the German scholarship reads it, of the struggle against the paganism of a wild country.

His cult is among the most enduring of southern Germany. In 851 his relics were raised and translated into a new church at Füssen under Bishop Lanto of Augsburg — the occasion of the Life — and a bone was sent to St Gallen. By about 1100 the tomb was found empty of its bones; what remained to the abbey was a fragment of relic and the insignia of the saint — the staff, cross and chalice of Magnus, kept at Füssen.

Feast and commemoration

September 6 (church date; Old Calendar civil September 19), in the GB&I layer of the St Constantine York calendar: "St. Magnus, disciple of St. Columbanus and Abbot of Füssen (c. 665)." Orthodox England keeps him the same day ("Magnus (Magnoaldus, Maginold, Mang) … He founded the monastery of Füssen in Bavaria"), and September 6 is his day in the German dioceses. He is not found in the OCA's Lives of the Saints (checked 2026-07-29). No Orthodox proper service is known; the common of a venerable father applies.

Iconography

Magnus is depicted in the Western tradition as an abbot in monastic habit with staff and book; the dragon of his Life — the image under which it casts his victory over paganism — is his distinguishing attribute. The basilica of St Mang at Füssen, built over his cell, is the centre of his imagery. No licence-clean image was stored for this entry (no icon fetching in this pass); the candidates would be Western works under the repository's labelling rule.

Disputed questions

Chronology. The Life makes Magnus the companion of Gallus (†c. 627) and simultaneously the contemporary of Wikterp of Augsburg, who died about 749 — an impossibility it does not notice. Modern scholarship therefore treats the Columbanus-Gallus connection as the ninth-century author's construction (perhaps conflating two men of the same name) and places the historical Magnus's mission under Wikterp in the eighth century: the Neue Deutsche Biographie gives his dates as c. 683 – September 6, 756 (following Tüchle, against the more commonly cited 772). The York calendar transmits the traditional dating (†c. 665), and this entry indexes under the seventh century following its witness, with the dispute recorded here.
The text of the Life. Beside the 851 Ellwangen composition, the Life survives chiefly in a version reworked about 1067 by Othlo, monk of St Emmeram — a second layer of distance between the reader and the saint, noted by the German scholarship as making historical verification of details impossible.
Irish origin. Orthodox England says he was born in Ireland, as do many modern notices — the natural inference from the Life's Columbanian setting, and the reason he stands in a British Isles and Ireland calendar. The Life's own evidence for this is part of the disputed construction above; the claim is transmitted here as the tradition's, not as established fact.
Other saints named Magnus. He is not to be confused with the venerable Magnus the Venerable of the Greek synaxarion (June 28), who reposed at prayer; nor with the martyr Magnus numbered among the Nine Martyrs of Cyzicus (April 29); nor with the Western bishops Magnus of Anagni (August 19), Magnus of Oderzo (October 6) or Magnus of Milan (November 5).
