Santuario di Fonte Colombo (1223): dove Francesco scrisse la Regola definitiva e, due anni dopo, si rivolse a “frate Fuoco” prima del ferro rovente
Nell’estate del 1223, ritiratosi per quaranta giorni in una stretta fessura di roccia sotto la chiesetta della Maddalena — il “Sacro Speco” — Francesco d’Assisi scrisse la Regola definitiva del suo Ordine, approvata da papa Onorio III quello stesso autunno. Due anni più tardi, gravemente malato agli occhi, tornò qui per sottoporsi a una cauterizzazione con ferro rovente dalla tempia al sopracciglio: prima dell’operazione, si rivolse direttamente al fuoco, chiamandolo “frate”, chiedendogli di essergli cortese. Secondo la tradizione, non sentì alcun dolore.
About the Sanctuary of Fonte Colombo
The Sanctuary of Fonte Colombo, one of the four Franciscan sanctuaries of Rieti’s “Valle Santa” (Holy Valley), is the place where, three years before his death, Francis of Assisi undertook the definitive drafting of the Rule of the Friars Minor. In the summer of 1223, Francis retired in prayer for forty days within a wide rock fissure — the Sacro Speco, or Holy Cave — beneath the small church of the Magdalene, where tradition holds he received divine confirmation of the Rule he had written; the completed text was formally approved by Pope Honorius III that same autumn. Two years later, in 1225, Francis, now seriously ill in his eyes, was persuaded by Cardinal Ugolino — the future Pope Gregory IX — and by his own brothers to travel to Rieti, where skilled eye physicians were available, and underwent a harrowing operation at Fonte Colombo: the attending doctor cauterised the veins running from ear to eyebrow with a red-hot iron, in the belief that this would halt the flow of humours afflicting the saint’s eyes. As his brothers withdrew, unable to watch, Francis is said to have addressed the glowing iron directly as “Brother Fire,” asking it to treat him with courtesy and gentleness — and tradition holds that he felt no pain from the procedure at all. The sanctuary was formally recognised as a site of historical and artistic interest in August 2024.

History
Fonte Colombo’s dual role — as the site of the Franciscan Order’s most consequential legal and spiritual document, the definitive Rule of 1223, and as the setting of one of the most vivid personal episodes in Francis’s own biography, his 1225 eye cauterization — gives this single sanctuary an outsized concentration of significance within Franciscan history, combining institutional and deeply personal dimensions of the saint’s life within the same rock formation. Francis’s address to “Brother Fire” before the cauterization, extending the same personifying, fraternal language he used toward the natural elements in his later Canticle of the Creatures, situates this episode as a direct lived expression of the same spirituality that would find its most famous literary form only shortly afterward, in the final year of his life.
Cardinal Ugolino’s direct personal involvement in persuading Francis to seek medical treatment at Rieti — a cardinal who would later become Pope Gregory IX and go on to canonise Francis in 1228 — connects this episode of physical suffering directly to the highest levels of the Church hierarchy that would shortly afterward formalise the saint’s own sanctity.
What you see
The Sacro Speco, the rock fissure beneath the chapel of the Maddalena where Francis retreated to write the Rule, remains the sanctuary’s most historically resonant space. The wider complex includes the chapel of San Michele, a cloister, and further chapels documenting episodes from Francis’s life, set within the wooded hillside above Rieti that gives the “Valle Santa” its name.
