In 2012 a hitherto unknown 'Eyckian' drawing of the Crucifixion was exhibited in The Road to Van Eyck in Museum Boijmans Van Beuningen. Forty years earlier Wim Hofman, a psychiatrist and art collector from Groningen, had bought the drawing - as a reproduction - for just ten guilders at a local estate auction. He was convinced, however, and rightly so, that it was an original work of art, and he spent the rest of his life researching it. The Rotterdam museum acquired the drawing shortly after the exhibition. In this book leading specialists examine various aspects of this mysterious drawing - its discovery, the scientific and technical research into the materials, and the identity of the artist. Is it a work by Jan van Eyck himself or a workshop assistant, or is it a late fifteenth-century copy of a work by the famous progenitor of Netherlandish painting?
