The Seville Cathedral altarpiece: A microbiological and chemical survey of the dust

A microbiological and chemical survey of the dust on the Seville Cathedral's altarpiece, the largest in the world, reveals critical insights into its degradation. The study, conducted prior to a 1977 restoration intervention, identified significant structural issues such as wood deterioration, flaking polychromy, and gilding loss, alongside microbial activity contributing to material decay. The research employed chemical analysis and microbiological techniques to assess the altarpiece's condition, providing a foundation for targeted conservation strategies. These findings underscored the need for urgent stabilization measures, including wood consolidation and material attenuation, to preserve this monumental Renaissance masterpiece.
