The present restoration has allowed the Museum’s Technical Documentation and Analysis Laboratory to study the work and reach a series of conclusions on its state of preservation, the materials used by the artist and its technique.

In general, the research undertaken revealed the painting’s good state of preservation and determined that the type of preparation used is closer to that used by Rubens in Flanders to those that he deployed in Madrid. In addition, it was technically demonstrated that the additions are later ones made by a different painter, while finally, the original size of Rubens’s canvas could determined.
