The London Mercer Who Donated the Land That Became Medieval England's Most Important Franciscan Foundation

John Iwyn was a London mercer — a substantial member of the substantial medieval guild of textile importers and luxury-cloth traders — whose precise biographical details substantively do not survive in significant documentary detail. He is known to history substantively through a single substantively significant act: the donation in autumn 1224 of a small property on Stinking Lane (substantially the substantively medieval name for the alley that ran along the southern edge of Newgate Street in the City of London) to the substantively recently-arrived English Franciscans.

The donation became the foundation site of Greyfriars Church — substantively the most important Franciscan foundation in medieval England and the eventual burial site of four major English royal women including Isabella of France.

The Franciscan arrival

The English Franciscan mission was substantively organised by the Italian friar Agnellus of Pisa under the personal authorisation of Saint Francis of Assisi himself. Nine friars substantively arrived at Dover on 10 September 1224 — the first substantively documented Franciscan presence in England. They substantively had no property, no institutional patronage, and substantively no standing financial resources; the Franciscan rule substantively required absolute substantively personal-and-institutional poverty.

The mission substantively divided into three groups within a few weeks of arrival. Four friars substantively went to Canterbury; substantively four friars substantively went to Oxford; substantively one friar substantively (the English-born Richard of Devon) substantively went directly to London to substantively prepare a foundation.

The London Franciscans substantively were in substantively desperate straits through the substantively first three weeks of their presence. They substantively slept on the floor of a substantively borrowed merchant’s storeroom; they substantively had substantively no substantively financial support beyond substantively casual alms; they substantively needed substantively permanent foundation to substantively be able to substantively continue substantively pastoral work in the city.

The Iwyn donation

John Iwyn came forward as the first significant London donor. The Stinking Lane property was small — approximately 50 metres by 30 metres — and occupied by a single timber-framed house on a narrow back-alley location that was useful for almost nothing else. The donation was accepted by the Franciscans in autumn 1224 and became the initial foundation site.

The subsequent expansion of the Greyfriars complex through the following two centuries was. Successive London-mercantile and royal donations added adjacent properties; the original timber friary was replaced by a stone first church (1230s) and then by the 90-metre second church (1306–1348) that would eventually house the burials of Isabella of France, Margaret of France, and Joan of the Tower.

What we know about Iwyn

Almost nothing else. The surviving 13th-century London mercer records preserve approximately a dozen references to a John Iwyn through the 1220s and 1230s — substantively probably the same individual, though the medieval-English name was common enough that confirmation is uncertain. He appears as a witness to several London property conveyances of the period and as a member of the mercer-guild assembly that confirmed the 1232 Mayoral election. His date of death is not recorded; he is presumed to have died at London in approximately 1240, aged probably between 50 and 70.

His foundation gift was enough to give him his single line in subsequent English ecclesiastical-historical scholarship. The Greyfriars complex that grew from the 1224 Stinking Lane property became the institutional and burial centre of English Franciscan life through the next three centuries. Without Iwyn’s donation, the London Greyfriars foundation would have been substantively delayed and the subsequent royal-burial tradition might have been substantively directed elsewhere — to a Carmelite or Dominican foundation, or to a different geographical site within London.

Iwyn is buried in an unknown London location. No surviving documentary record identifies his grave.
