Quick Summary
Jeroen Dik is a Dutch art historian and professor at TU Delft specializing in art conservation science. He has pioneered non-invasive imaging technologies such as X-ray fluorescence mapping to reveal hidden paintings beneath masterpieces by van Gogh, Rembrandt, and other Old Masters. His work is crucial for museums, collectors, and researchers worldwide, providing insights into artistic techniques, authentication, and restoration while minimizing the risk of damage to priceless works of art.
Who is Jeroen Dik?
Jeroen Dik is a professor of materials in art and archaeology at Delft University of Technology (TU Delft) in the Netherlands. Trained as both an art historian and conservation scientist, he has become one of the leading figures in technical art history, a field that merges chemistry, physics, and digital imaging with traditional art scholarship.
His academic journey began with studies in art history at Utrecht University, followed by specialization in conservation science. At TU Delft, his teaching and research focus on applying advanced technologies to the study of paintings, sculptures, and archaeological objects.
What is Jeroen Dik Known For?
Jeroen Dik is internationally recognized for his use of scanning technologies to study paintings. His most famous contribution came in 2008, when he and his team uncovered a hidden portrait beneath a Vincent van Gogh painting using X-ray fluorescence scanning. The discovery revealed an earlier portrait of a peasant woman that van Gogh had painted over, showcasing how the artist reused his canvases.
Beyond van Gogh, Dik’s work has revealed underdrawings, compositional changes, and hidden layers in works by Rembrandt, Rubens, and other masters. These discoveries provide crucial insight into artistic processes, material choices, and historical context.
How Does Jeroen Dik’s Technology Work?
The cornerstone of Dik’s research is the use of non-invasive imaging techniques. Unlike traditional sampling methods that require removing small fragments of paint, his technologies preserve the integrity of the artwork.
X-ray Fluorescence Scanning (XRF)
This technique scans a painting with X-rays, exciting the atoms within the pigments. Each chemical element emits a unique signal, allowing researchers to map the distribution of pigments across the canvas. This makes it possible to reconstruct hidden layers or underpaintings.
Infrared Reflectography
By using infrared light, researchers can see beneath surface paint layers, revealing preliminary sketches or underdrawings that artists used to plan compositions.
Multispectral Imaging
This involves photographing artworks under different wavelengths of light, from ultraviolet to infrared, to reveal varnish layers, pigment alterations, and past restorations.
Together, these methods allow scholars to virtually peel back layers of paint, creating a timeline of the artist’s creative process.
Why is Jeroen Dik’s Work Important?
Jeroen Dik’s work is important for multiple reasons:
Preservation of Art
His non-invasive imaging reduces the need for destructive sampling, helping museums and collectors conserve fragile artworks safely.
Art Historical Insights
Discoveries of hidden layers provide direct evidence of artistic techniques, decision-making, and evolution over time.
Authentication and Provenance
Scientific analysis helps determine whether a painting is genuine or a forgery, protecting collectors and institutions from fraud.
Cultural Heritage Protection
Dik’s methods contribute to UNESCO’s mission of preserving world heritage, ensuring artworks remain intact for future study.
Practical Applications of Jeroen Dik’s Research
Museums and galleries worldwide apply Dik’s methods to research and conservation. For example:
The Van Gogh Museum in Amsterdam has used XRF scanning to reveal details about van Gogh’s paint mixtures and working methods.
The Rijksmuseum in Amsterdam collaborates with TU Delft on projects involving Rembrandt’s works, combining imaging with 3D scanning for restoration planning.
Private collectors increasingly rely on these technologies before purchasing high-value paintings.
Challenges in Art Conservation Science
While Jeroen Dik’s technologies are groundbreaking, they face challenges:
Accessibility: High-resolution scanners and spectroscopic equipment are expensive, limiting access for smaller museums.
Data Complexity: Interpreting the massive datasets from scans requires advanced expertise in both art and physics.
Ethical Questions: Revealing hidden images may change how we view an artwork, raising questions about whether such knowledge should always be publicized.
Real-Life Examples of Discoveries
Several high-profile cases highlight the impact of Dik’s work:
Van Gogh’s Hidden Portraits: XRF scanning revealed multiple hidden images under van Gogh’s canvases, including a lost portrait of a peasant woman beneath “Patch of Grass.”
Rembrandt’s Techniques: Studies have shown how Rembrandt layered pigments to create lifelike textures, offering unprecedented insight into his mastery.
Rubens’ Revisions: Hidden sketches uncovered beneath Rubens’ paintings show his creative revisions, proving he often altered compositions mid-process.
The Future of Art Conservation Technology
As of 2025, Jeroen Dik continues to explore artificial intelligence (AI) and machine learning to process imaging data. AI helps recognize pigment patterns faster and predict artist techniques with greater accuracy.
Emerging tools like 3D imaging, nanotechnology, and augmented reality promise to make conservation more precise and accessible. Future exhibitions may allow visitors to “see” hidden layers of paintings in real-time using AR devices, turning Dik’s research into a public educational experience.
