Originally auctioned at Christie’s in London in 1928 and 1929, the piece was initially attributed to Titian. A later discovery of the signature led to renewed interest in its potential origin. Researchers employed Raman Spectroscopy to analyze the pigments, finding that most matched those used during the Middle Ages and Renaissance, but one pigment—Prussian blue—was not available until the 18th century, suggesting possible later restoration.
