Famed for his fantastic paintings and triptychs (such as The Garden of Earthly Delights) that invest religious subjects with wild visions of hell and demons, the late-medieval Dutch artist Hieronymus Bosch was a mysterious, unique personality whose work anticipated that of the Surrealists. 2016 is the 500th anniversary of Bosch’s death, and this documentary follows a team of Dutch art historians as they use infrared cameras to examine the sketches beneath the paint of Bosch’s 25 extant works, in order to discover more about the artist’s intentions, and to establish which of the paintings can be attributed to Bosch himself or to his students and followers. In English and in Dutch, Spanish, Italian with English subtitles. Writer/Director: Pieter van Huystee. (Netherlands 2015) 87 min.
