The Nurture of Jupiter

Salvator Rosa

The Nurture of Jupiter, 17th Century

Bistre (Brown) Ink and Charcoal on Paper


A 17th century Italian painter, draughtsman, etcher, poet, and actor, Salvator Rosa is well-known for his originality and extravagance. Primarily known for wild and mountainous landscapes, Rosa’s repertoire also includes more macabre subjects, philosophical allegories, and grand historical themes.  There is also a significant relationship between Rosa’s satirical poetry and his painting. 

Current Condition of the Artwork: 

The drawing paper was significantly damaged by insects, probably silverfish, and there are scattered small to moderate losses throughout. There is a cluster of loss to the paper and drawing located at the center right. There is significant skinning to the paper surface and media, most notably in the top left quadrant. The paper was previously repaired by mounting it to a secondary wove paper, which was then mounted to a larger, thicker laid paper. The ink has bled laterally from the “wet” mounting technique and the charcoal under-drawing is pale and smudged. The paper is discolored overall and there is a dark area where the paper is discolored at the center left. 

Conservation Treatment Proposed: 

  • Remove matte.
  • Clean surface and remove accretion.
  • Remove hinges.
  • Wash and apply alkaline rinse and buffer if safely possible.
  • Mend/reinforce and line with Japanese paper and wheat starch paste.
  • Insert losses with cellulose powder of similar.
  • Humidify and flatten.
  • Inpaint.
  • All materials used will be appropriate and conservation quality. All work will adhere to the highest standards of the field. 

Estimated Cost of Treatment:  $3,500.00
