Mona Lisa
Today the "Mona Lisa" is considered the most famous painting in the world, but until the 20th century it was simply one among many highly regarded artworks.
Once part of King Francis I of France's collection, the "Mona Lisa" was among the first artworks to be exhibited in Louvre, which became a national museum after the French Revolution. From the 19th century Leonardo began to be revered as a genius and the painting's popularity grew from the mid-19th century when French intelligentsia developed a theme that it was mysterious and a representation of the femme fatale.
The Baedeker guide in 1878 called it "the most celebrated work of Leonardo in the Louvre", but the painting was known more by the intelligentsia than the general public.
The 1911 theft of the "Mona Lisa" and its subsequent return was reported worldwide, leading to a massive increase in public recognition of the painting. During the 20th century it was an object for mass reproduction, merchandising, lampooning and speculation, and was claimed to have been reproduced in "300 paintings and 2,000 advertisements". It has been said that the "Mona Lisa" was regarded as "just another Leonardo until early last century, when the scandal of the painting's theft from the Louvre and subsequent return kept a spotlight on it over several years."
Speculations about Mona Lisa
In 2004, experts from the National Research Council of Canada conducted a three-dimensional infrared scan. Because of the aging of the varnish on the painting it is difficult to discern details. Data from the scan and infrared were used by Bruno Mottin of the French Museums' "Center for Research and Restoration" to argue that the transparent gauze veil worn by the sitter is a guarnello, typically used by women while pregnant or just after giving birth. A similar guarnello was painted by Sandro Botticelli in his "Portrait of Smeralda Brandini" (c. 1470/1475), depicting a pregnant woman on display in the Victoria and Albert Museum in London. Furthermore, this reflectography revealed that "Mona Lisa"'s hair is not loosely hanging down, but seems attached at the back of the head to a bonnet or pinned back into a chignon and covered with a veil, bordered with a sombre rolled hem. In the 16th century, hair hanging loosely down on the shoulders was the customary style of unmarried young women or prostitutes. This apparent contradiction with her status as a married woman has now been resolved.
