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.
