Rembrandt van Rijn made the painting "Jeremiah" at the age of 24. It’s an incredibly complex painting in which all his talent comes together: The enchanting effect between sketchy finish and the small detail. But also the expression of all the different materials such as velvet, metal, red coral and rock. Team member Michel van de Laar has restored Rembrandt’s work in the past and discovered that there is something special hidden in the paint: A hair by Rembrandt. Also in the reconstruction, a hair will be put back. And not just any hair: an exciting search leads to a descendant of Rembrandt.
