At 17, Michelangelo cut a deal with a priest. He would carve the church a wooden statue. In return, he got to slice open the dead bodies kept in its back room. The Church saw cutting up the dead as a sin, so he worked quietly. He kept at it for years, long enough to learn the human body better than most doctors of his time. Then he painted that secret into the most famous ceiling on Earth.
You have seen The Creation of Adam. Two fingers reaching across a gap, almost touching. Now look past the hands, at the red cloth wrapped around the older man on the right. In 1990, an American doctor named Frank Meshberger sat staring at that shape and worked out what it was. A brain. Slice a real one down the middle, lay it over the painting, and the folds and curves match up.
The crease under the pointing finger lands exactly where a deep groove cuts across a real brain. A kneeling figure’s leg sits where the nerves behind your eyes cross over. The brain stem, the big artery at its base, the little gland that runs your hormones, all of it in the right place. And those two famous fingers never actually meet. There is a thin gap between them, the same kind of gap a signal has to jump to get from one brain cell to the next.
One painting could be a coincidence. So in 2010, two scientists at Johns Hopkins studied another stretch of the same ceiling. There is a panel where the old man’s neck looks swollen and lumpy and wrong, and people had bickered about it for centuries. Michelangelo could paint a flawless neck in his sleep. He made this one strange on purpose. Set it beside a real brain stem and the shapes are the same. He had tucked one into the throat. A few of those details would not show up in any anatomy book for more than three hundred years.
Now, plenty of smart people think this is all nonsense. Our brains are built to find patterns. We see faces in clouds and rabbits in the carpet, so maybe we are doing the same thing here. That lumpy neck has also been called a swollen thyroid, or the brain of a fish. Fair enough.
But think about who this man was. He cut open the dead for ten years, until a powerful family came after him for dissecting one of their own. He once wrote that his real skill lived in his head, and the hands only followed. Give a man like that a blank ceiling and total freedom, and he puts the brain in the one scene that calls for it: a still, empty body filling, for the first time, with a human mind.
This rabbit was supposed to be dinner. In 1919 a French farmer found one in his barn with patchy, balding fur, figured it was a sick runt, and tossed it in with the meat rabbits headed for the local priest. The priest took one look at the soft, velvety coat and pulled it out of the meat pile.
The farmer's name was Désiré Caillon. The priest, Abbé Gillet, knew nothing about genetics. He could just tell that the fur on this little animal felt different from every other rabbit in the French countryside. So he bought a second one with the same coat from Caillon and started breeding them.
By 1924, Gillet had about 150 of them. He sold his first batch (one male and two regular females) for 6,000 francs, which was roughly $1,000 at the time. He called the breed Castorrex, mashing together the French word for beaver (the fur looked like beaver pelts) and the Latin word for king.
That same year, the rabbit went on display at the Paris International Rabbit Show. Two American breeders, John Fehr and Alfred Zimmerman, bought a pair and shipped them home. By 1929, the breed was officially recognized in the US.
The velvet coat comes from a single missing letter of DNA, tucked inside a gene called LIPH. LIPH makes a chemical the body needs to grow normal rabbit hair. Take that one letter out, and the long stiff outer hairs (the ones that stick up on a regular rabbit) shrink down until they are the same length as the soft fluffy hairs underneath. Every hair on the animal ends up the same height. That is what makes the coat feel like velvet when you run a hand over it.
The same mutation also packs the hairs much closer together. The best Rex coats fit 15,000 to 38,000 individual hairs into a single thumbnail-sized patch of skin, roughly the same density as chinchilla fur.
The black-and-tan look in the photo comes from a completely separate gene. Breeders call it the otter pattern. It paints the back, head, and ears solid black, then turns the belly, the rims of the eyes, and the insides of the ears a soft cream color, with a reddish line where the two halves meet. The same kind of markings you see on a Doberman.
The fur industry still treats Rex pelts as the closest substitute for beaver, seal, and chinchilla. The whole breed exists because a village priest a hundred years ago looked at a runt nobody wanted and saw something worth keeping.
