In 2016, the Noordbrabants Museum in the Dutch city of Den Bosch held a special exhibition devoted to the work of Hieronymus Bosch, who died 500 years ago. This late-medieval artist lived his entire life in the city, causing uproar with his fantastical and utterly unique paintings in which hell and the devil always played a prominent role. In preparation for the exhibition, a team of Dutch art historians crisscrosses the globe to unravel the secrets of his art.
