Pigment analysis of painting signed 'L daVinci' finds Renaissance materials and later alterations
Researchers at Uppsala University analyzed pigments in a painting signed 'L daVinci.' Most are consistent with Renaissance materials, but one more recent pigment appears linked to later alterations.
Researchers at Uppsala University analyzed the color pigments in a painting signed 'L daVinci.' Most pigments are consistent with Renaissance-era materials. A more recent pigment appears to be linked to later alterations. The study shows how materials science can add pieces to an artwork's history.
Our reading
Our reading is that the finding adds material evidence about the painting's history but does not by itself confirm the signature's attribution.
What to do or watch
What to watch is whether further evidence can clarify the date and cause of the later alterations and whether that evidence bears on the 'L daVinci' signature. The pigment analysis alone does not resolve the painting's attribution.
