Mona Lisa
The painting is thought to be a portrait of Lisa Gherardini, the wife of Francesco del Giocondo, and is in oil on a white Lombardy poplar panel. It had been believed to have been painted between 1503 and 1506; however, Leonardo may have continued working on it as late as 1517. Recent academic work suggests that it would not have been started before 1513. It was acquired by King Francis I of France and is now the property of the French Republic, on permanent display at the Louvre Museum in Paris since 1797.
Roberto Vittori
The astronaut also had a painting of the artist George Pusenkoff titled "Single Mona Lisa (1:1)" with him and took photos with it on the International Space Station. It is the ultimate continuation of the project "Mona Lisa Travels" developed by Pusenkoff and could only be realized under difficult conditions. The authorities found the idea good in theory, but constantly put forward new reasons why the project was unrealizable. Only when George Pusenkoff wrote to the then Italian ambassador in Russia, Gianfranco Facco Bonetti, the possibility of realizing the idea arose. The connection between science and art, which was also important in Leonardo da Vinci's life, found here an "actualization" in the form of this journey of an image of Mona Lisa into space. For the action, Pusenkoff's painting was removed from the frame so that it could be rolled. On April 25, 2005, Vittori took the painting back to the Earth with him.
