Several interesting discoveries were made after infrared and ultraviolet light examinations were carried out on the painting.
An infrared examination uncovered a large spade pentimento in the lower right corner of the picture (see image). The asparagus bundle that sits in the lower right corner of the patinting, appears to have also been repositioned.
An ultraviolet light examination highlighted a thin overall modern varnish that fluoresces a bluish tone. The edges of the picture showed residues of an earlier thicker natural resin varnish that wasn’t completely removed, in which fluoresces a milky green colour (see image). A few varnish runs are seen on the surface suggesting that the painting was varnished in an upright position. This examination also showed dark outlines to the cabbage and goat, possibly where thin paint was strengthened with retouching.
