Nine centuries before science took an interest in the power of scent, a Benedictine monk had already made an unexpected discovery: that the nose might be the truest path to the sacred.
The Scent of Saints
How an 11th-century monk made smell the sense of the sacred
Buried in the forgotten archives of the Middle Ages lies a text almost no one knows today — and yet it tells one of the strangest theories ever written about scent. Its author: Thiofrid, Benedictine abbot of the monastery of Echternach, in present-day Luxembourg, who died in 1110. His subject: the idea that a saintly body, even reduced to dust after centuries, continues to exhale a supernaturally sweet fragrance.
An abbey haunted by the memory of a scent
It all begins with Willibrord, the Anglo-Saxon monk who founded Echternach, who died in 739. According to the legend preserved by the abbey’s monks, on the day of his burial, « a fragrance of wondrous sweetness had filled everyone’s nostrils » — a sign, it was said, that angels had come to attend the funeral.
This was only the beginning of an olfactory story that would span centuries. In 1031, nearly three hundred years after the saint’s death, Abbot Humbert had his tomb reopened for the consecration of a new church. What he found left him speechless: the body, almost intact, gave off « such fragrances as if it had been steeped in every precious ointment. » Asked what he had seen and smelled, Humbert fell silent — unable, it is said, to put words to what he had perceived.
Smelling the divine rather than seeing it
It was this oral tradition, passed down from one generation of monks to the next, that Thiofrid decided to commit to writing around 1100, in a treatise with a poetic title: the Flores epytaphii sanctorum — literally, « flowers laid upon the epitaph of the saints. »
For Thiofrid, smell was no minor sense — far from it. He made it the supreme faculty for perceiving the sacred, superior even to sight. A decaying body, he wrote, « no living man in the flesh can look upon without nausea. » But scent does not deceive: « nothing in it is fetid, nothing ignoble » when it comes to the flesh of a saint. Where the eye perceives only remains, the nose detects a presence.
This theology of scent draws its roots from the Song of Songs, where the holy soul is compared to a lush garden whose « spices flow forth » for the heavenly Bridegroom. Thiofrid carries the metaphor to its conclusion: the saint’s flesh becomes a « bridal chamber » steeped in the fragrance of Christ — a fragrance so powerful it « cannot be stopped or contained within the tomb. »
A scent that outlasts centuries
What strikes the reader of Thiofrid is his insistence on duration. He recalls that the fragrance of Saint Stephen’s relics had been perceived 382 years after his death; that of Willibrord, 292 years after his. To him, this was the ultimate proof: an ordinary scent fades, but the scent of sainthood is incorruptible — because it does not come from the body, but from the Spirit dwelling within it.
He even offers his own testimony, with an almost startling humility: in the gallery adjoining the church of Echternach, « I was flooded and restored by the healing fragrance breathing forth from the aromatic garden » — he who, he admits, ordinarily gives off nothing but « the foul stench of sin. »
An intuition that science would later confirm
What Thiofrid sensed through faith, French anthropologist and philosopher Annick Le Guérer would document through research, nine centuries later. A specialist in the history of smell and perfume, she notes in her work that fragrance has always served three essential functions: religious, therapeutic, and seductive — a trinity that finds one of its most complete expressions in Thiofrid’s Flores. In her books Les Pouvoirs de l’odeur and Le Parfum, des origines à nos jours, Le Guérer explores how, across cultures and eras, smell was long regarded as the sense best suited to reveal the invisible — an intuition that Western philosophy paradoxically dismissed for centuries, deeming it too primitive, too close to the animal. Thiofrid’s treatise, written nearly nine hundred years before this scholarship, stands as striking proof: long before science took an interest, a Benedictine abbot had already made smell the royal road to the sacred.
From relic to bottle
Nine centuries on, this medieval intuition — that a scent can carry something immaterial, lasting, almost sacred — has lost none of its force. The materials Thiofrid unknowingly evokes (incense, myrrh, benzoin) are precisely those that, to this day, inhabit some of niche perfumery’s most inhabited compositions. These are not notes like any other: they are materials that, since Antiquity, have accompanied rites, temples, and tombs — and that continue, in a bottle, to tell the very story Thiofrid was trying to put into words: that a scent can be a trace of something greater than ourselves.
