Paintings with a similar subject have been faced several times by Amigoni and his workshop. The one presented here is a very valuable version but later than the painter's autographs.
(see A. Scarpa Sonnino, Jacopo Amigoni, Soncino, 1994, pp. 130 / 31m cat. No. 33)
The painting, relined, has a large network of cracks, a small hole at the top right, drops of color. No repaintings are visible.
