Leonardo da Vinci's thumbprint was discovered in a drawing by the Renaissance master belonging to Queen Elizabeth II.
The hidden details are revealed in a new book entitled "Leonardo da Vinci: a closer look". This book analyzes 80 drawings by Léonard from the royal collection, shedding new light on the work of a famous artist.
The thumbprint was found on "The Cardiovascular System and Main Organs of a Woman," anatomical drawing of Leonardo dating from about 1509-1510.
PICASSO MASTERPIECE REVEALS LOST PAINTING, HIDDEN DETAILS
"In the center of the left edge of the sheet, the print is in the same reddish-brown ink as the lines in the drawing," says the Royal Collection Trust. "One can only conclude that, after creating the work, Leonardo, left-handed, picked up the sheet with inked fingers."
Alan Donnithorne, the author of the book, is the former head of paper conservation at the Royal Collection Trust. In his research, he used the techniques of X-ray fluorescence, microscopy and ultraviolet imaging to study the drawings.
In the statement, Donnithorne notes that Leonardo has used a host of different types of paper. A careful analysis of "The Head of a Bearded Old Man in Profile", a drawing of 1519, shows that the paper contains straw and rope fragments that the paper maker used to repair the leaf.

Other works have revealed their secrets in recent years. Last year, for example, scientists exploited sophisticated radiography and imaging technologies to reveal a lost painting and other hidden details in a Picasso masterpiece.
The painting, "La Misery Crouching", is a major work of the blue period of Picasso. A high-tech analysis of the 1902 painting, however, revealed how Picasso painted a landscape on a landscape. Buried images related to other works by Picasso have also been found.
DISCOVERING VAN GOGH: PREVIOUS DRAWINGS UNKNOWN BY THE IDENTIFIED MASTER
In 2017, a secret "ghostly" portrait of Mary, Queen of Scotland, was discovered under a 16th century painting. X-ray technology was used to reveal the unfinished portrait of the Scottish queen, who ruled from 1542 to 1567.
The portrait of Mary was painted with the portrait of Sir John Maitland, 1st Lord Maitland of Thirlestane. The 1589 painting of Maitland, who was Lord Chancellor of Scotland, was awarded to the Dutch artist Adrian Vanson.
Da Vinci continues to be a source of fascination for historians.

In addition to using his own shorthand, Leonardo also wrote his personal notes beginning with the right side of the page. It is unclear whether this mirrored writing was a way to keep his notes confidential or simply a way to prevent smudging, since Leonardo was left-handed.
