Most of us can agree that the idea of eternal life/dwelling forever in some species of paradise sounds appealing. However, not many people think of the physical body itself as being death-proof - which is why the image of the "incorruptible" saint is so enduringly fascinating. For centuries, the Catholic church (and some Buddhist temples, as well) have housed the remains of icons who are supposedly immune to decomposition and decay as we know it. Macabre as it may be, the preservation and display of these bodies represents a holy tradition, even though incorruptibility is no longer considered a miracle by the Vatican.
Incorruptibility itself is an increasingly fluid term that can mean any number of things. A corpse that's initially uncannily preserved can start to decay after a time, as bodies are wont to; or only certain parts of the corpse (like their heart or an isolated hand or limb, for example) can be left intact. In any and all cases, a saint, once canonized, is always a saint, whether their mummified remains are reposing amid splendid settings or they're little more than a bejeweled skeleton.
Below are some examples of figures that have stood the test of time as well, or infinitely better, than anybody could be expected to.
Dashi Dorzho Itigilov
Dashi-Dorzho Itigilov takes center stage as perhaps the most grotesque and interesting saint on this list. An esteemed Russian Buddhist monk, he's said to have passed away mid-chant in 1927. As he'd requested to be buried in whatever pose he ended up dying in, he was interred sitting up, in the lotus position.
In 1955, and again in 1973, he was exhumed and found to be uncorrupt. He was unearthed a third (and, it's said, final time) in 2002, and his body was found to be "in the condition of someone who had died 36 hours ago." The appearance of the monk's remains don't exactly jive with this assessment, but there is no doubt that he looks mighty good (if "good" is the way you want to put it) for someone who shuffled off this mortal coil 90 years ago.
Itigilov's remains reside in Ivolginsky Datsan, a Buddhist temple in Russia. They are said to sit outdoors, under a tree, and one can easily envision observers, taking a casual stroll along an idyllic garden path, doing a startled double-take as they come upon him.
However, there is some intrigue surrounding the location of his remains, with reports that the monk's body may have been stolen.
Rosalia Lombardo, one of the world's most enchanting (and sad) corpses, is not officially recognized as a saint by the Church, but many devout believers consider her to be one. Even almost 100 years after her passing, her impeccably preserved mortal form evokes pathos, sympathy, and a sense of awe at her beauty.
Born in Palermo, Italy, in 1918, Rosalia died of pneumonia at age two, and her devastated father, unable to accept her death, commissioned "master" embalmer and taxidermist Alfredo Salafia to preserve her. According to reports, a combination of "formalin, alcohol, salicylic acid, and glycerin" has kept her basically intact. With her wavy hair, perfect features, and porcelain skin, she still appears (more or less) as she did in life ... as long as you don't look too closely. (There's also reports that her eyes have occasionally opened, though that proposition seems dubious.)
MRI scans of Rosalia's form eerily resemble footage of alien autopsies, but, astonishingly, most of her organs are still intact. She rests in the Capuchin Catacombs of Palermo in Sicily, and her beauty and peaceful expression have led to her being popularly dubbed “Sleeping Beauty."
St. Victoria of Rome
St. Victoria of Rome is one of the church's most psychologically unnerving, fascinating, and sinister relics. In life, she was arrested and executed for her Catholic faith (a tragedy that's reflected by the red slash in her throat), and her uncorrupted body was installed in the Church of Santa Maria della Vittoria in Rome.
However, Victoria's golden curls, alabaster brow, and perfect features aren't precisely what they seem to be. According to Morbid Anatomy,
This figure, one of the city's least known but most macabre sights, appears to be a statue. But closer inspection reveals something far more spine-chilling ... when you look into the slightly open mouth, you see through the open lips of a skeleton ... indeed, this is the body of the saint herself, very much "touched up" with wax, human hair, and clothing.
In other words, Victoria is an initially radiant figure who gradually deepens into a decaying ghoul, the longer you look at her - an image made to inspire a thousand horror novels, if there ever was one.
St. Bernadette of Lourdes
St Bernadette of Lourdes, France, died in 1879, after supposedly witnessing 18 manifestations of the Virgin Mary. However, her path to sainthood was a long one: she wasn't canonized until 1933. And the process of said canonization apparently required multiple episodes of disinternment. According to Atlas Obscura,
Her body was exhumed three separate times, in 1909, 1919, and finally in 1925 ... [she] was pronounced by the church as officially "incorrupt," but it seems the qualifications for that term may have been somewhat lax.
"Lax" is one way of putting it. The doctor present at the 1910 exhumation phrased it thus:
The body is practically mummified, covered with patches of mildew and quite a notable layer of salts, which appear to be calcium salts… the skin has disappeared in some places, but it is still present on most parts of the body.
Ultimately, several of Bernadette's ribs were removed and shipped off to Rome as relics. The rest of her now reposes in the Chapel of Saint Gidard at the Sisters of Charity in Nevers, France.
However, officials still feared that the "'blackish color' of the saint's face might be off-putting to pilgrims." Hence, a "light wax mask" was installed; its porcelain composure now hides the patchy mildew beneath.
