There is something deeply fascinating in the idea that a sheet of paper, left intact for over five hundred years, can still hold a physical trace of one of humanity’s greatest geniuses. Not a pencil mark or a line of blood, but something infinitely more intimate: the DNA of Leonardo da Vinci.
This is the suggestion that comes from new international research. The scholars claim to have recovered genetic material from a drawing attributed to Leonardo da Vinciopening a completely new window on the way in which the artist observed, interpreted and perhaps “saw” the world.
It all revolves around a 16th century red chalk drawing, known as the Holy Child (Holy Child). In April 2024, researchers from the Leonardo da Vinci DNA Project performed an operation as simple as it was very delicate: they passed a swab similar to those used for diagnostic tests over the surface of the sheet, collecting what the paper had absorbed over time.
Paper, explain the biologists involved in the study, is a living material. Retains sweat, skin cells, bacteria, DNA fragments. Unlike large paintings, continually touched, restored and cleaned over the centuries, Leonardo’s drawings and notes have remained more “protected”, making them ideal candidates for this type of analysis.
Among the traces identified there are plant residues compatible with the environment of Renaissance Florence, but also sequences of human DNA. And this is where the research gets really interesting.
The Y chromosome and the link with Leonardo’s Tuscany
Scientists focused on the Y chromosome, a part of DNA that is passed down almost identically from father to son. The comparison took place between the genetic material recovered from the drawing and another sample extracted from a letter written by a cousin of Leonardo.
The result is not definitive proof, but it is far from trivial. Both samples belong to a genetic group that shares a common ancestor in Tuscany, the region where Leonardo was born in 1452. A coherent clue, which strengthens the hypothesis that that trace could really belong to him.
The researchers themselves urge caution. Attributing DNA with certainty to a historical figure is extremely complex, especially in the absence of certified reference samples. But the step taken is defined as a possible turning point.
What if DNA explained the unique way Leonardo saw the world?
The most fascinating question comes next. If that DNA was really Leonardo’s, what could it tell us about him? For some time, scholars and art historians have wondered about an extraordinary ability that clearly emerges from his drawings. Leonardo was able to capture details that escape the human eye, as if he were observing slowed down reality. In his sketches appear imperceptible movements, tiny vortices of water, fleeting moments like the alternating beat of the wings of a dragonfly in flight.
According to some geneticists, his eyes seemed to “sample” the world at a much higher speed than average, almost like a video camera capable of recording up to 100 frames per second, compared to the 30-60 normally perceived. An extraordinary visual sensitivity, which could also have a genetic basis.
The involvement of genes linked to the functioning of the retina, such as KCNB1 and KCNV2, responsible for the transmission of visual signals, is hypothesized. For now these are hypotheses, but the idea that a part of his genius could be written in his DNA is fascinating and disturbing at the same time.
Because proving that that DNA is really his is so difficult
The real obstacle remains the definitive confirmation. As the project experts explain, genealogy does not always coincide with biology. Finding living descendants is not enough: continuous and verifiable male genetic lines are needed.
For this reason, researchers are working on sequencing the DNA of some male descendants of the Da Vinci family, identified in a recent genealogical study. Comparison with other samples taken from the notebooks and drawings could, step by step, strengthen or disprove the initial hypothesis.
Only after obtaining solid evidence will it be possible to evaluate a possible analysis of the remains attributed to Leonardo, which are believed to be kept in Amboise, France. An extremely delicate operation, also from an ethical and historical point of view.
Between genius and mystery
Painter, scientist, inventor, anatomist, engineer, musician. Leonardo da Vinci was all of this together, and much more. His most famous works, from Mona Lisa toLast SupperuntilVitruvian Mancontinue to tell us about balance, observation and boundless curiosity.
Today, centuries later, it is not only his drawings that tell us who he was. It could be his own biology that suggests an answer, reminding us that genius never comes from nothing, but from the mysterious encounter between body, mind and environment. And perhaps, in that thin layer of time-worn paper, Leonardo is still trying to tell us something.
