In 2016 the Noordbrabants Museum in the Dutch city of Den Bosch held a special exhibition devoted to the world of Hell-bent surrealist Hieronymus Bosch. In preparation for the exhibition, a team of art historians crisscrossed the globe to unravel the secrets of his art. Using special infrared cameras, for example, they examined the sketches beneath the paint, giving the most detailed look to date at how this devilish artist worked his sinister magic.
