The face of a woman, the leaves that adorned her hair, her red dress remained hidden for almost four centuries under the colors laid out later by the author of the painting. To clarify this “cold case” of painting were the experts of the National Institute of Nuclear Physics of Cnr thanks to the image obtained with their special X-ray scanner called Landis-X. Technicians and researchers flew to Norwich, England, to be screened in view of the “The Paston Treasure” restoration, a large-scale work that is therefore difficult to move, and which is now on display in the Castle Museum. The painting, considered an important pictorial testimony of the history of English art, was commissioned by Sir William Paston to a Flemish itinerant painter in the seventeenth century.

The examinations

The discovery is due to a team of researchers from the Southern National Laboratories of the Institute of Nuclear Physics (INFN) and the Institute for Archaeological and Monumental Heritage (Ibam) of the CNR. “Despite the important dimensions of the painting, the real-time imaging technique of the Landis-X mobile scanner has allowed us to fully document the work – commented Claudia Caliri, from the National Laboratories of the South – through the images of the elemental distributions obtained during the measures it was possible to know the nature of the pigments used by the artist and to study his creative process “. 


Paint the grass perfectly and paint a lawn, paint a lawn: the colors in the shade, the colors in the light; paint the grass; how to prepare the backdrop for painting a lawn; which colors to use to paint a lawn, which techniques to use to paint grass and lawns: paint the grass with acrylics, paint a lawn with oil colors; paint a prairie; color a meadow with crayons or colored pencils

Painting the image of a lawn with oil or acrylic – but also making it with pencils or oil pastels or skinny pastels – is certainly a task that can be underestimated, but which presents, in reality, many difficulties for the purposes of a realistic rendering of the painting. And in some respects, centering the vibrations of green and tonal variations can be the added value to our painting.
