Neither seen, nor known - The hidden fate of 25 masterpieces

The fate of 25 painting masterpieces revealed by scientific imaging
Repentance, repainting, reuse: beneath the paint hide sketches, outlines, characters, pieces of landscapes, and sometimes entire compositions.

To the naked eye, under infrared, ultraviolet, X-ray light... the artist's intentions and gestures can resurface, as well as the interventions of a restorer. A man hidden under Boucher's The Odalisque, a change in format in Rembrandt, a strap lowered then raised in Sargent, a mischievous cherub erased in Watteau, a cupid covered in a Vermeer.

Why these changes? Journalist Sarah Belmont investigated, assisted by experts, and explains the creative process of painters in a fun and accessible way.

Because behind the great History lie small stories of feelings, money, and style.
