There are two attributions regarding the origin of these paintings, one points to a Spanish origin while the other one suggests that they were painted in a workshop of the Cuzco region. During a restoration of the series in 2005 several microsamples were extracted from original and repainted areas of the twelve paintings and analyzed by Raman microscopy and scanning electron microscopy coupled with energy dispersive X-ray spectroscopy (SEM/EDS). High performance liquid chromatography (HPLC) was applied to confirm the presence of organic pigments. The aim of our work was to establish if there were differences in the color palette of the 18th and 19th centuries Sibyls and if it was possible to contribute to the elucidation of the origin of the series based on the materiality of the paintings
