It cannot be determined exactly when Leonardo began to perform dissections, but it might have been several years after he first moved to Milan, at the time a centre of medical investigation. The work of Leonardo Da Vinci is an invaluable heritage of the 15th century. Overall, the results show a surprising dominance of bacteria over fungi. Da Vinci augmented his art with copious notes written in “mirror-writing”, a technique reserved for work he wanted to keep personal. His “helical airscrew” (c. 1487) almost seems a prototype for the modern helicopter, but, like the other vehicles Leonardo designed, it presented a singular problem: it lacked an adequate source of power to provide propulsion and lift. In 2019, her team was able to investigate the storage conditions and even the possible geographical origin of three statues requisitioned from smugglers through the study of their microbiome and, earlier this year, the microbiome of ancient parchments allowed to elucidate the animal origin of the skins used for their manufacture 1,000 years ago. Leonardo was also quite active as a military engineer, beginning with his stay in Milan. These anatomical drawings by Leonardo da Vinci from the Queen’s collection at Windsor Castle have been selected and displayed as a synthesis of Leonardo’s contributions to art and science in a field of endeavor that occupied him for a period of nearly thirty years, from about 1485 to 1510–15. He believed the workings of the human body to be an analogy, in microcosm, for the workings of the universe. Leonardo Da Vinci, or commonly referred to as Leonardo, was born in 1452 in a town called Vinci in Florence, hence the surname Vinci. Could molecular studies reveal interesting data from the past?

Over the following two decades, he did practical work in anatomy on the dissection table in Milan, then at hospitals in Florence and Rome, and in Pavia, where he collaborated with the physician-anatomist Marcantonio della Torre. Matthew Hopkins was an infamous witch-hunter during the 17th century, who published “The Discovery of Witches” in 1647, and whose witch-hunting methods were applied during the notorious Salem Witch Trials in colonial Massachusetts. Jørgen Brønlund was one of the participants in the legendary Mylius Erichsen's Denmark Expedition to Greenland 1906-08. He managed to break down a phenomenon into its component parts—the traces of water or eddies of the whirlpool—yet at the same time preserve the total picture, creating both an analytic and a synthetic vision. Imposing the principles of geometry on the configuration of the human body, Leonardo demonstrated that the ideal proportion of the human figure corresponds with the forms of the circle and the square. Here, a high proportion of these bacteria are either typical of the human microbiome, certainly introduced by intensive handling of the drawings during restoration works, or correspond to insects microbiomes, which could have been introduced, a long time ago, through flies and their excrements. Leonardo’s early anatomical studies dealt chiefly with the skeleton and muscles; yet even at the outset, Leonardo combined anatomical with physiological research. The molecular study of art pieces has already proved to be a valuable approach, and Dr Piñar, first author of the study, is not at her first try. Black Friday Sale! These questions led an interdisciplinary team of researchers, curators and bioinformaticians, from both the University of Natural Resources and Life Science and the University of Applied Science of Wien in Austria, as well as the Central Institute for the Pathology of Archives and Books (ICPAL) in Italy, to collaborate and study the microbiome of seven different drawings of Leonardo Da Vinci.
