Researchers used advanced EVA film technology to analyze Leonardo da Vinci's "Donna Nuda." This non-invasive method revealed his painting techniques, including tempera grassa and conifer resin protection, offering new insights into Renaissance art.

Area of Science:

  • Art Conservation Science
  • Materials Science in Art
  • Analytical Chemistry for Cultural Heritage

Background:

  • Leonardo da Vinci's "Donna Nuda," housed at the Hermitage Museum, is a significant Renaissance artwork.
  • Previous studies identified some materials used by Leonardo but lacked comprehensive analysis of his techniques.
  • Understanding Leonardo's artistic recipes is crucial for art history and conservation.

Purpose of the Study:

  • To explore the surface of "Donna Nuda" using novel analytical techniques.
  • To decipher the specific drawing and painting techniques employed by Leonardo da Vinci.
  • To investigate the materials and methods used for surface protection and glazing.

Main Methods:

  • Utilized ethylene vinyl acetate (EVA) film technology for non-invasive surface sampling.

  • Applied EVA films (embedded with ion exchangers and C8/C18 resins) for 60 minutes on different painting areas.
  • Analyzed eluted materials using gas-chromatography/mass spectrometry (GC/MS) and liquid chromatography/mass spectrometry (LC/MS).

    • Main Results:

    • Confirmed the use of "tempera grassa" (linseed oil and egg yolk) throughout the painting.
    • Identified a protective layer of conifer resin on the painting's surface.
    • Detected rosemary oil as a diluent, used to facilitate glazing and achieve aerial perspective in the landscape.

    Conclusions:

    • This study provides the first in-depth analysis of a Leonardo painting using modern techniques to decipher his artistic methods.
    • EVA film technology offers a powerful, non-invasive approach for analyzing cultural heritage objects.
    • The methodology has potential applications in authenticating artworks and detecting art fraud.
