In the 16th century someone decided that Da Vinci’s notebooks had to be dismembered. It took us 400 years to solve their mistake.

Upon his death, in 1519, Leonardo da Vinci He left more than just paintings and frescoes that crown him as one of the great references of Renaissance painting. Just as (or even more) important to understanding the depth of his genius are his personal notebooks, full of notesillustrations, graphics… come from his own handwriting and sprinkled with his characteristic mirror writing. By chance of history, in the 16th century this bibliographical treasure suffered a ‘act of editorial vandalism’ that has conditioned the way we understand Leonardo. Until now. An unfortunate legacy. The name of Francesco Melzi Maybe it doesn’t tell you much. And it’s normal. Melzi was an Italian painter of the 16th century whose memory has been eclipsed for posterity by geniuses of the stature of Michelangelo, Raphael Sanzio and Leonardo Da Vinci, of whom he was a disciple. However, Melzi does stand out for something, a role that has conditioned our way of understanding the author of ‘La Mona Lisa’: upon Leonardo’s death, Melzi became his executor, responsible for looking after his manuscripts. That enormous legacy made up of hundreds and hundreds of manuscript sheets ended up in the hands of Pompeo Leoni (1533-1608), a sculptor from Arezzo, in Tuscany, who one day decided to dismember Leonardo’s notebooks. The result was disastrous, although to be honest Leoni’s objective was not to destroy the notebooks, but to ‘reorganize’ them following an arbitrary criterion. And what was the result? Basically Leoni dedicated himself to separating, classifying and putting together sheets of Leonardo’s notebooks and loose pages in a whimsical way. Based on what he considered best. The result was that many of the annotations that Da Vinci had recorded in the same set of manuscripts between the mid-1470s and his death in 1519 were divided into two different codices. In one, the largest, Leoni included all material (drawings and writings) of a technical or scientific nature. The second, smaller codex was reserved for material that in his opinion had an artistic and figurative character. From Italy to England. Leoni’s ‘attack’ did not end there. At the beginning of the 17th century his son-in-law, Polidoro Calchi, decided to get rid of the material he had inherited from the sculptor, which caused Da Vinci’s old notebooks to end up scattered around the world, separated by hundreds of kilometers. The first codex, that of technical annotations, today known as Codex Atlanticusended up in the hands of Count Galeazzo Arconati, who in turn donated it in 1637 to the Veneranda Biblioteca Ambrosiana. The second codex traveled even further. Around 1620 he ended up in England and half a century later was integrated in the Royal Collection at Windsor. Righted the wrong. More than four centuries later that capricious dismemberment of Da Vinci’s annotations has been amended at last. At least in part. A few days ago the Italian embassy in the United Kingdom, the Ministry of Culture and representatives of the Galileo Museum, the Veneranda Biblioteca Ambrosiana and the Royal Collection Trust presented in London a new tool named ‘Leonardotheka 2.0’. The name gives a clue to its approach: it is nothing more nor less than an immense ‘library’ digital of Da Vinci’s legacy, a resource that allows many of the manuscripts of the Renaissance genius to be consulted in an accessible and agile way. The Galileo Museum slide that from now on, whoever wishes will be able to explore the material by accessing the archives independently or with cross searches, in addition to “the results of more than 200 years of research” on Da Vinci’s career and work. 3,500 pages. Beyond that advantage, what is really important about Leonardotheka 2.0. is that, as remember The authorities of Florence have gathered around 3,500 manuscript pages by Leonardo that in some cases had been separated since the end of the 16th century. It is a virtual union, not a physical one, but it is still a milestone and helps to right the mistake made centuries ago by Pompeo Leoni. In total, the digital library brings together the 1,119 folios of the Codex Atlanticus and 550 pages from the Royal Collection of Windsor. Some sources specify that it is about one third of Da Vinci’s entire surviving legacy, which also includes the codices preserved in Madrid. Is it that important? Regardless of what it may mean for researchers, Leonardotheka 2.0 is important for several reasons. The main one is that it has allowed us, in words of the Galileo Museum, “reconstruct the original state of Leonardo’s manuscript legacy before Leoni’s disastrous intervention” in the 16th century. And that is not a minor detail. Although the separation between art and science might make sense to Leoni, the truth is that goes against of the Renaissance mentality that Leonardo embodied. “It offers a new perspective on his thinking, vision and working methods,” they underline from Florence. “The platform highlights the connection between scientific studies and the figurative drawings of the Tuscan genius.” Beyond Leonardo. “This project not only helps to recover the complexity of Leonardo’s work in its original form, but also contributes to the new interpretation, in development for several years, of this crucial period in European history. Using digital tools designed to analyze the original texts, Leonardotheka 2.0 will make this challenge possible,” highlights Michele Ciliberto, from the National Institute of Renaissance Studies. Filling gaps. The second reason why the project is so important is that it has allowed us to recover pieces that had been damaged when the notebooks were dismembered in the 16th century. To be more precise, those responsible for the Leonardotheka they assure who have been able to “reconstruct” 50 manuscripts “thanks to the insertion of fragments preserved in Windsor within the pages of Codex Atlanticus, restoring their original context.” One of the reconstructions carried out by the experts has made it possible to “reconcile” the drawing of a horse preserved in the British collection with a note on an equestrian monument preserved in the Codex Atlanticus. “The restored folio probably … Read more

Marie Curie died 92 years ago. Your personal notebooks are still buried under layers of lead for a good reason

If you visit the basements of the National Library of France (BnF) and you want to look at some of the bibliographic gems that are kept there, you will most likely be forced to respect a series of measures, such as wearing gloves or handling the books in perfectly controlled conditions. The objective is obvious: protect the volumes. From you, from excessive exposure to light, from degradation. Things change if what you want to read is one of the notebooks that Marie Curie scribbled in her laboratory. In that case it is you who they must protect. Literally. The fact that there are dangerous publications may be a controversial statement that may or may not be shared, but in the case of the folios handwritten by the famous Franco-Polish scientist, it leaves little room for debate. Despite Madame Curie He died in 1934, almost 89 years ago, his notebooks continue to cause concern among archivists. and it is quite normal so be it. When Marie Salomea and her husband, Peterinvestigated in their laboratory with uranium, little was known about the potential damage of radiation, so they did not apply the basic safety measures that govern any radiological task today. So things—supports the American Council on Science and Health (ACSH)— “no wonder his workspace and notebooks became contaminated.” Pierre and Marie Curie, in the laboratory, around 1904. To avoid possible risks, the handwritten notebooks are kept in the basements of the National Library of France inside special boxes, made up of several layers of lead. Not only that. As detailed in 2021 by the BBC networkthe French institution requires researchers who want to handle the notebooks in person to first put on some protective suits specials and, of course, that they sign a document in which they exempt them from any responsibility. Is such misgivings justified? When reading requires a special suit For their research, which led to the discovery of polonium and radium, the Curies accumulated, crushed and manipulated enormous quantities of minerals containing uranium in their laboratory. He knowledge about natural radioactivity It was very recent at the time and the couple, who contributed to their research, were unwittingly exposed to its harmful effects. Themselves and, of course, all the material they used. Including notebooks of notes. To understand the conditions under which they worked, it is good review the notes by Marie, collected by Philipp Blom in ‘The years of vertigo: Europe, 1900-1914’: “One of our joys was entering the workshop at night; everywhere we saw the faintly luminous silhouettes of the capsule bottles containing our products. It was a beautiful sight and always new to us. The glowing tubes looked like dim fairy lights.” It was not strange, they say, that the pair of scientists carried flasks with polonium and radium in their coat pockets or kept them in their desk. Marie herself ended up dying in 1934 from a aplastic anemia which was probably caused by his frequent exposure to radium samples and polonium. “Taking into account the half-life of 1,600 years of the radius and the sensitivity of current radiation detectors, it is also not surprising that this contamination is still detectable today,” comments the ACSH in an article dedicated to the topic. The experts, BBC specifiescalculate that given that on average radium atoms take about 15 centuries to disintegrate, it is not unreasonable to think that the notebooks should remain in their lead box during that period. The National Library of France is in any case not the only one to preserve Curie’s notebooks. The Wellcome Collection It also has a volume, digitizedwith notes on experiments and radioactive substances and sketches. The volume dates from between 1899 and 1902 and was written in Paris. To avoid scares in 2014 The Aurora firm examined the material and concluded that it was contaminated with radius-226. The ACSH states in any case that the volume “does not represent an appreciable risk.” Fortunately, the notebook can consult now from homeonline, or even downloaded in PDF. The theme of “the contaminated notebooks” of Curie generate so much interest that it even has your own entrance on the website Marie-curie.eu, focused on the figure of the two-time Nobel Prize winner, and numerous articles have been written on the subject. Notebooks are not the only ones in a similar situation. The BBC explains that the house south of Paris where Marie Curie worked until 1934 is also affected by the radiation levels generated during her experiments. The block has even earned the ironic nickname of “Chernobyl on the Seine”. When he was buried in Paris Pantheoneven Marie Curie herself ended up in a lead sarcophagus almost an inch thick.
