Variation on Francesco Cairo

Farsettiarte, from Italy, sells on 30 October 2015 a "Lombardian School, 17th century" Martyrdom of Saint Agnes, estimated at 2,800 to 3,800 Euro.

It is a copy with variations of a work by Francesco Cairo (1607-1665) from the Galleria Sabauda in Turin (information and image from FondazioneZeri). The painting for sale looks less subtle, less of a painting and more of a drawing, e.g. in the arm of the killer. But it is nevertheless painted with a lot of skill, and if not by Cairo is made by a good painter anyway. If it was by Cairo, it would be worth ten times the estimate: as a copy, the price is probably about right.
