Advanced imaging technology from the Brookhaven Labs and the European Synchrotron Radiation Facility (ESRF) in Grenoble has revealed an authentic Rembrandt self-portrait in an art authenticity effort involving leading art historians and scientists at the two labs. The hunt for authenticity all began when a private collector showed art historians in Amsterdam a small panel “Old Man with a Beard” from about 1630. The collector wanted to know if it was a Rembrandt.
The experts turned to the modern science of x-ray imaging for answers. The scientific work showed an unfinished self-portrait by Rembrandt under the paint surface.
The ESRF and Brookhaven sites performed the scientific explorations. Ernst van de Wetering, emeritus professor of art history at the University of Amsterdam and head of the Rembrandt Research Project, said the evidence was clear that this is a Rembrandt.
The scanning technology that was used at ESRF was a dual energy X-ray imaging technique. The Brookhaven National Lab used used Macro-scanning X-Ray Fluorescence spectrometry (MA-XRF). Central to Brookhaven’s contribution was its new fluorescence microprobe system that can scan surfaces with high definition. The XRF technique was used with this new “Maia” detector system.Prof Ernst van de Wetering, an art historian at the Rembrandt House in Amsterdam, and head of the Rembrandt Research Project, had worked meanwhile with his team to examine the sketch for authenticity. The imaging results gave scientific support to authentication, which Prof. van de Wetering announced at the Rembrandt House Museum in Amsterdam on Friday.
From 1 May to 1 July 2012 the Rembrandt House Museum is staging a special exhibition of research into ten paintings by Rembrandt and his contemporaries using XRF technology.
