Mirin of Paisley

The Holy Mirin (Meadhrán) of Paisley, Bishop and Confessor, Disciple of Comgall of Bangor

Bishop · Venerable · d. c. 620

Commemorated 15 September — His day in the Aberdeen Martyrology and the Scottish calendars

Mirin (Meadhrán, Merinus — the Merryn of this calendar) was an Irish monk of the sixth and early seventh centuries, given as a child to Comgall to be trained in the great monastery of Bangor on Belfast Lough, where he took the habit and became prior. He crossed to the British kingdom of Strathclyde and ended his days at Paisley, where he slept in the Lord about 620 and where the church — later the great Cluniac abbey of Paisley — was dedicated in his honour. The Aberdeen Breviary preserves his acts and the Aberdeen Martyrology styles him bishop and confessor; he is venerated in both Scotland and Ireland, and his day in the Scottish calendars is September 15.

Bangor. The acts of Mirin in the Aberdeen Breviary (1510), summarised by Forbes, are circumstantial. He was given by his parents to Comgall, to be trained in the monastery of Bangor — Comgall's Bangor in the Ards of Ulster, the most rigorous school of monastic Ireland, which also formed Moluag of Lismore — and there he eventually assumed the monastic habit and became prior. His rule was a gentle one. The Breviary tells that once, when Finnian of Movilla came to the monastery in Comgall's absence and asked for milk when there was none, the cellarer at Mirin's bidding brought milk from the cellar, and it was distributed among them that sat at meat. It tells also that he laid the pains of childbirth on an Irish king who had contemned him; that one of the community once saw him in his cell surrounded by a heavenly light; and that he recalled to life a brother who had fallen, overcome by thirst and fatigue, in the valley of Colpdasch (a place not identified).

Strathclyde and Paisley. At length, the Breviary concludes, full of miracles and holiness he slept in the Lord at Paisley — Pasletum, in the British kingdom of Strathclyde, within easy distance of Dumbarton — and in his honour the church there was dedicated to God. Forbes observes that a colony from Bangor at Paisley is not at all improbable, and finds a corroborating trace in Colgan: the lost Kalendar of Cashel noticed "SS. Medranus et Tomanus in una ecclesia in Britannica Arcluidensi" — a Medranus in a church of British Strathclyde. When the Cluniac priory of Paisley was founded in the twelfth century from Wenlock, its church was dedicated to S. Milburga, S. James and S. Merinus — the retention of the local saint alongside the newcomers indicating, as Forbes notes, a veneration already long established on the spot. The Aberdeen Martyrology's entry for September 15 commemorates "in Scotland saint Mirin, bishop and confessor, at Paisley, where his monastery, dedicated with sumptuous structure, was endowed by the merits of illustrious kings of the Scots, and where various miraculous proofs of his sanctity are manifest."

Traces of the cult. Beyond Paisley, Forbes records Kirk Mirren, a vanished chapel and churchyard in the parish of Kelton in Kirkcudbright; S. Mirren's Chapel, ruined, on Inch Murryn, the largest island of Loch Lomond, marking an old connection with the abbey of Paisley; S. Mirrin's Well at Kilsyth; and the farm of Knock Murran in the parish of Coylton in Ayrshire.

The date. Orthodox England and the Ramsgate Book of Saints place his repose about A.D. 620, and the chronology of the acts agrees: a disciple of Comgall (†c. 601) and a younger contemporary of Finnian of Movilla (†589) belongs to the turn of the sixth and seventh centuries. The dating curiosities of the late Scottish antiquaries are noted below.

Feast and commemoration

September 15 (church date; New Calendar civil September 15, Old Calendar civil September 28). The witness is the calendar of the Antiochian Archdiocese of the British Isles and Ireland (St Constantine York feed), whose GB&I layer for this day reads "St. Merryn, bishop of Bangor (620)." Independent corroboration of the day is strong on the Scottish side: the Aberdeen Martyrology, Adam King's Kalendar and Dempster's Menologium Scoticum all keep him on September 15 (Forbes's Kalendars of Scottish Saints prints all three), as do Orthodox England — the York calendar's named upstream, "Merinus (Merryn, Meadhran), Sept 15, †c. 620" — and the Ramsgate Book of Saints. Camerarius gives September 17. No Greek, Slavonic or North American Orthodox calendar consulted carries him (OCA September 15 checked live, absent). No proper service exists; the common of a hierarch — or, following his monastic state, of a venerable — would be used.

Iconography

No Orthodox icon of Mirin is known, and no mediaeval image of him is recorded in the sources consulted. Modern depictions exist at Paisley — where he remains the town's patron — including stained glass in Paisley Abbey; these are twentieth-century copyrighted works and are not storable. A lead is recorded in the the list of icons still being sought queue.

Disputed questions

  • "Bishop of Bangor"? The York calendar's line styles him "bishop of Bangor." No source consulted makes him bishop of Bangor: the Aberdeen Breviary and Martyrology style him bishop (without naming a see) while making him a monk and prior of Bangor and placing his repose at Paisley, and Adam King's Kalendar calls him "abot of paslay." The calendar line appears to have fused the episcopal style with the name of his monastery; the fusion is recorded here and not adopted in the prose. The bishop classification follows the Aberdeen sources' style, alongside his monastic state.
  • The day. September 15 in the Aberdeen Martyrology, Adam King's Kalendar and Dempster's Menologium Scoticum (and in Orthodox England, the Ramsgate Book of Saints and the York calendar); Camerarius alone gives September 17, and also makes him afterwards abbot of Newbattle in Lothian — which Forbes flatly calls impossible (Newbattle was a twelfth-century Cistercian foundation). Dempster records that some placed him under a King "Fincormachus" about the year 319, an antiquarian back-dating incompatible with the Comgall connection and noted only as a curiosity.
  • The Irish martyrologies. No Meadhrán stands at September 15 in the martyrologies of Óengus, Gorman or Donegal as consulted; the Medráns they carry at June 6 and June 8 (of Saighir, and of Cell Murchon) are different men. The Irish side of his veneration asserted by the Ramsgate Book of Saints ("venerated as a Saint both in Scotland and in Ireland") rests on the Bangor tradition rather than on a martyrology entry found this pass.
  • Not to be confused with Merinus of Bodferin (January 6), the disciple of Dunawd at Bangor-on-Dee (Bangor Iscoed) in Wales, patron of Bodferin in Caernarvonshire, venerated also in Brittany — a different saint whose similar name and similar monastery-name ("Bangor") make the confusion peculiarly easy; Orthodox England lists the two Merinuses in consecutive entries.
  • Not to be confused with the St Merryn of Cornwall who names the parish of St Merryn near Padstow, whose feast is July 7 and whom the mediaeval episcopal registers of Exeter call Sancta Marina — on Baring-Gould and Fisher's showing a female saint (perhaps Marina of Bithynia, perhaps a corruption of Morwenna), and in any case not the Sept 15 disciple of Comgall.
