Eye for detail

Pascal Cotte found Mona Lisa’s painting originally included both brows and lashes
Pascal Cotte found Mona Lisa’s painting originally included both brows and lashes.

For centuries, the Mona Lisa has beguiled art buffs unable to resist speculating on its origin and meaning. Now a French inventor claims to have some answers, including the fate of the enigmatic subject’s famously missing eyebrows and lashes. Parisian engineer Pascal Cotte said his ultra-detailed digital scans of the painting allow him to effectively burrow through layers of paint to "see" into the past of Leonardo Da Vinci’s 16th-century portrait of a Florentine merchant’s wife.

The world’s most famous painting originally included both brows and lashes, according to Cotte, who said his 240-megapixel scans reveal traces of Mona Lisa’s left brow, obliterated by long-ago restoration efforts.

"With just one photo you go deeper into the construction of the painting and understand that Leonardo was a genius," Cotte said at the US debut of an exhibit detailing his findings. As a boy growing up in Paris in the 1960s, Cotte said, he spent hours staring at the Mona Lisa the first time he saw it at the Louvre. He later used his scientific training in light and optics to develop a camera that would let him examine the object of his obsession. Cotte, 49, estimated he has spent 3,000 hours analysing the data from the scans he made of the painting in the Louvre’s laboratory three years ago. Using sensors to detect light from both the visible spectrum and the infrared and ultraviolet ranges invisible to the human eye, Cotte said, his camera allowed him to make these and other findings: 1. Da Vinci changed his mind about the position of two fingers on the subject’s left hand. 2. Her face was originally wider and the smile more expressive than Da Vinci ultimately painted them. 3. She holds a blanket that has all but faded from view today. — AP
