An international team of researchers works on Italy to analyze the DNA in objects associated with Leonardo da Vinciwith the aim of reconstructing his genetic profile and providing data on his genius. The research includes family letters from the 14th century, archival drawings and sketches, and employs advanced sequencing techniques to recover biological traces preserved for centuries.
According to an article published in National Geographicthe project Leonardo DNA Projectbegun in 2015, analyzed the surface of works of art, correspondence and historical documents linked to the artist. The team used surface swabs and whole metagenome sequencing to identify biomes of bacteria, fungi, plants, viruses and human genetic traces. The results, published in January on the site bioRxivpoint out that the chromosome “AND” found in several objects coincides with a common genetic lineage in Tuscany, Leonardo’s native region.
Additionally, researchers examined works such as the “Santo Niño” drawing, attributed in part to da Vinci himself. According to the Leonardo DNA Project, biological profiles differ by material, conservation and context, which turns these objects into “living fingerprints” of their environment and those who manipulated them throughout history.
From these findings, scientists highlight the complexity of attributing genetic identity to Leonardo da Vinci with certainty. According to the anthropologist David Caramellifrom the Leonardo DNA Project and the University of Florence, more samples and artifacts are required to validate current observations. The analysis included short-read sequencing data and forensic genetic profiling that allowed human genetic information to be extracted from the surface of the documents.
The study also noted that, Although matching male lineages have been detected in letters and works of art, the authenticity of those samples is not yet definitive. Storage conditions, handling and environmental exposure influence the preservation and composition of genetic material. Therefore, experts considered that establishing an unequivocal biological identity is extremely complex and that the next steps include analyzing Leonardo’s notebooks, tombs and other works.
The debate on the relationship between genetics and genius remains open. According to information released by the Leonardo DNA Project, some specialists pointed out that certain biological traits, such as Leonardo’s extraordinary vision, could have a genetic basis. The project statement mentioned research on genes associated with retinal signal speed, which could have influenced the accuracy of their scientific and artistic observations.
However, other experts, such as art historian Leonardo Domenico Laurenza, quoted by the magazine mentioned above, maintained that Leonardo’s genius is better explained by his cultural and economic environment, rather than by an exclusively biological cause. The possibility of combining genetic data and historical analysis could, in the future, offer a more complete view of the factors that contributed to da Vinci’s creativity.
Thus, the Leonardo DNA Project represents an advance in techniques for studying ancient DNA in works of art and historical documents. The Researchers plan to expand the analysis to other objects and contexts related to Leonardo da Vinci, in hopes of identifying genetic “signatures” or microbiomes that allow for new attributions of authorship and a deeper understanding of your life.
The president of the project, Jesse Ausubel, from Rockefeller University, stressed that the developed methodology can be applied in the future to study other historical figures and solve puzzles about the authorship of works and correspondence. Ausubel highlighted that Leonardo used to use his fingers to paint, which increases the possibility of finding cells from his epidermis mixed with pigments and artistic materials.
In this way, the search for genetic clues in objects linked to Leonardo da Vinci opens a new chapter in the study of the great names of the Renaissance. Although genetics does not fully explain genius, scientific advances promise to add valuable information about the life and work of the Italian polymath, combining the rigor of biological analysis with the richness of the historical and cultural context.
