Many art conservators have long claimed that a recently uncovered landscape painting attributed to an 18th-century master must be an authentic early work because its canvas weaving matches techniques unique to that period. However, recent spectroscopic analysis revealed trace quantities of a synthetic blue pigment—one that was not commercially synthesized until the mid-19th century—embedded within the foundational primer layers of the canvas. This finding demonstrates that the artwork could not have been executed during the era to which it was originally attributed. Therefore, museum curators ought to remove the painting from the upcoming Renaissance exhibition and reclassify it as a later derivative.
