Leonardo da Vinci's Rare Drawings Make Debut in US Exhibit.

The Martin Luther King Jr. Memorial Library in Washington, D.C. will host the "Imagining the Future - Leonardo da Vinci: In the Mind of an Italian Genius" exhibition from June 21 to Aug. 20, featuring some of the pages from the "Codex Atlanticus," a massive collection of Leonardo da Vinci's drawings and written notes from 1478 to his death in 1519. The drawings, permanently housed at the Biblioteca Ambrosiana in Milan, Italy, were brought to the United States thanks to a partnership between libraries facilitated by the Italian trade association Confindustria. The exhibition will showcase 12 drawings for a self-propelling cart, sketches for wings on flying machines, designs for hydraulic pumps and more.

The Mystery of Black Stains on Leonardo da Vinci's Codex Atlanticus Solved.

Researchers at the Politecnico di Milan in Italy have identified the cause of mysterious black stains on a folio of Leonardo da Vinci's Codex Atlanticus as starch and vinyl glues applied during an earlier restoration effort some 50 years ago. They also found nanoparticles of a mercury sulphide called metacinnabar in the protective paper holding the folio, although it is unclear how this unusual black crystalline phase might have formed. In 2020, scientists analyzed the microbes found on seven of da Vinci's drawings and found that each drawing had its own unique microbiome, dominated by bacteria rather than fungi, contradicting widespread belief.

Uncovering Leonardo da Vinci's Secrets in Codex Atlanticus Folio 843

Researchers at Politecnico di Milano conducted an in-depth study on folio 843 of the Codex Atlanticus, a collection of Leonardo da Vinci's drawings and writings, to understand the origins of black stains that appeared on the modern passepartout that binds Leonardo's original folios. The study revealed the presence of starch glue, vinyl glue, and inorganic nano-particles made up of mercury and sulfur, which had accumulated within the cavities formed between the cellulose fibers of the passepartout paper. The particles were identified as metacinnabar, a mercury sulfide in an unusual black crystalline phase, and were likely formed due to the addition of an anti-vegetative salt in the glue mixture used in Grottaferrata's restoration techniques and air pollution.
