Opportuna of Montreuil
French Benedictine nun

Opportuna of Montreuil (died 770) was a Frankish Benedictine nun and abbess. A Vita et miracula Sanctae Opportunae was written within a century of her death (c. 885–88) by Adalhelm (later rendered Adelin), bishop of Séez, who believed he owed his life and his see to Opportuna.
Life
When she was still young, Opportuna became a Benedictine nun at the convent called the Monasteriolum[a] near Almenêches, where her cousin Lantildis was abbess. Opportuna took the veil from her brother, Chrodegang (later rendered Godegrand), the bishop of Séez.[b] Although Montreuil was only three miles away from Séez, Chrodegang was murdered on the way to visit his sister at the abbey.[c] Later Opportuna succeeded her cousin as abbess. In this position, she was conventionally described as "a true mother to all her nuns", correcting their faults, significantly enough to record, with words, not blows.
Some sources say that Opportuna died[e] from a brief illness which was compounded by grief from the death of her brother, as Chrodegang had died on 3 September 769. His murder had been planned by Chrodobert, a powerful relation to whom he had entrusted the administration of his diocese during his seven years' absence at Rome. Though she foresaw her brother's death in a prophetic vision, Opportuna was powerless to intervene; afterwards she buried Chrodegang in her own convent. Whatever the cause, Opportuna died on 22 April 770.
Hagiography
Like all Carolingian saints, Opportuna's sanctity was not expressed in charismatic actions during her lifetime: she effected no miracles during her lifetime.
This brief starts where responsible research should: with the source description of “Opportuna of Montreuil” as french Benedictine nun. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as french Benedictine nun. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Oct 13, 2024. The linked authority identifier is Q1561994. VIAF identifies the subject as 221068697. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
