Focus on this artwork and analyze the Condition and conservation.
The panels received conservation treatments in the 1840s (transfer of paint from wood to panel support, and new frames), 1930, 1952 (retouching), 1958 (stabilization of paint), 1998 (UV glazing and anti-theft; cleaning and consolidation), and 2019. The transfer in 1840 caused some small losses requiring retouching, with flattening of the paint layers, and the weave of the canvas used for that transfer left some pattern on the central panel. Wolfgang Schöne wrote of damage and paint losses upon inspection in his 1938 dissertation, and confirmed what Paul Heiland had recorded in 1902/1903. The curatorial and conservation staff of the M – Museum Leuven act as custodians of the paintings.
