For centuries, two of the most intriguing question about Leonardo da Vinci’s “Mona Lisa” were “Who?” and “When?” A discovery made at Heidelberg University in 2005 pretty much answered both. A note written in a manuscript in the library confirmed the 【小题1】 of da Vinci’s first biographer, Giorgio Vasari: that the sitter was a merchant’s wife, Lisa Gherardini. The note also helped 【小题2】 the masterpiece to between 1503 and 1506.

A third mystery—“Where?”—is still in dispute, But on June 3rd a French engineer, Pascal Cotte, declared that he and a collaborator had identified the landscape in the background of the painting. Arguments had once been made for 【小题3】 of countryside in the Marche region and between Milan and Genoa. During a presentation in Vinci, near Florence, Mr. Cotte argued that the artist was more 【小题4】 depicting a part of his native Tuscany-one that much interested him at the time. According to this theory, da Vinci 【小题5】 the area not as it was, but as, in an unrealized scheme, he intended it to be.

Mr. Cotte, who was asked by the Louvre (where the “Mona Lisa” hangs) to create a digital image of the painting, is the inventor of the multispectral (多光谱的) camera: a device that can detect not only the drawing below the surface of an oil painting, but also, where they exist, intermediate layers of work. It was among these, under what appears to be a 【小题6】 rock, that he found a preparatory sketch showing that da Vinci intended it to represent a castellated(城堡形的) tower.

The landscape of the “Mona Lisa” also includes a huge steep cliff. That is similar to one that da Vinci included in a sketch of a fortress(堡垒) 【小题7】 by Pisa and Florence in the war that broke out between them in 1503 (around the time he was painting Gherardini). The fortress with the nearby cliff—and a tower, known as the Caprona tower—all overlook the river Arno as it snakes from Florence to Pisa. All three also 【小题8】 in drawings made by da Vinci to illustrate a plan about which, says Mr. Cotte, he became “obsessive”.

Mr. Cotte argues that a channel that 【小题9】 through desolate countryside at the right of the “Mona Lisa” is too wide to be a road, as some have speculated, and is instead the dried-up bed of the Armo as da Vinci pictured it once his plan had been adopted.

It never was. But if Mr. Cotte’s theory is right, it might just explain why Gherardini, a Florentine, wears such a 【小题10】, if mysterious, smile.
