Margaret of Cortona — 700 Years in a Crystal Reliquary
Too thin a record to say either way.
The account
Margaret of Cortona, a 13th-century penitent, died in 1297; her body has been displayed in the Basilica of Santa Margherita in Cortona for over 700 years and is described as incorrupt, though no modern independent forensic examination has been published.

A Life of Dramatic Conversion
Margaret of Cortona was born around 1247 in Laviano, Tuscany. After nine years as the mistress of a nobleman who was murdered, she underwent a conversion, joined the Third Order of Franciscans, and spent the rest of her life in penance, charity, and prayer in Cortona. She died on February 22, 1297, and was canonized by Pope Benedict XIII in 1728 — 431 years after her death.
The Cortona Display
Margaret's body has been kept at the Basilica of Santa Margherita in Cortona in a crystal reliquary for over 700 years. Her custodial history in Cortona has been relatively continuous, and the body has not been lost or refound over that span.
The Setting
Cortona sits at 600 meters elevation in Tuscany, with a dry climate historically favorable to preservation. The stone basilica provides thermal stability and low humidity. The crystal reliquary allows viewing while enclosing the remains. The University of Pisa examined Zita of Lucca, in a similar Tuscan stone-church environment, and identified natural desiccation mummification as the preservation mechanism there.
The Record
No equivalent examination of Margaret's remains has been published. No modern forensic chemical or histological analysis of her body is on record.
Reviewer Notes
We weigh a claim on two things, kept separate from the story above.
Assessed by Miracles Jar AI
Long-claimed preservation with consistent custodial history; natural mechanisms plausible; no forensic analysis available.
Long-claimed preservation with consistent custodial history; natural mechanisms plausible; no forensic analysis available. The case is very unlikely to be demonstrably supernatural — not because the preservation is doubted, but because it cannot be distinguished from natural mummification without examination.
Margaret of Cortona's body has been venerated in Cortona for over 700 years with consistent reports of preservation, making her one of the longer-claimed incorruptibles with continuous custodial history. Against this, Cortona's elevated Tuscan climate, the stone basilica, and the crystal reliquary provide favorable conditions for desiccation mummification, and no modern forensic chemical or histological analysis has been published.
The body has reportedly been preserved and displayed continuously for over 700 years in Cortona. Long continuous custodial history is unusual; most natural mummies are rediscovered after loss of custody. Cortona's elevation and Tuscan climate are favorable to desiccation mummification — similar environmental conditions to Zita of Lucca, where natural mummification was confirmed. No modern forensic chemical or histological analysis has been published; natural from supernatural preservation cannot be distinguished without tissue analysis.
The crystal reliquary may also create a microenvironment that retards further decay. Margaret is a legitimate candidate for scientific investigation — more tractable than some others, and she sits in the same evidential position as most medieval incorruptibles: genuinely preserved longer than expected, but without the forensic data needed to evaluate the mechanism.

What would raise this score: Long-term follow-up documenting permanence, in a condition with a near-zero spontaneous-resolution base rate, would raise the meter.
What would lower it: A documented relapse, or case literature showing the condition fluctuates or remits on its own, would move it down.
How this works
We keep two questions apart on purpose — so a thin record can’t make an impossible thing look proven, and a strong record can’t dress up an ordinary one as a miracle. First: Could nature explain it? (taking the account as true for the moment.) The question is whether nature could produce this at all — assuming, for the moment, the events are true as described. Second: is there real evidence it happened? A claim only stands out when both hold up — and we never call anything certain either way. How ratings work →
The natural explanation
The leading natural account for this case is spontaneous remission & the body's own recovery. Read what it explains — and where it stops.
