"Follower of Pieter Pourbus" is follower of Gillis Mostaert instead

Vassy & Jalenques, from France, sells on 14 March 2020 a "Flemish School, ca. 1600, follower of Pieter Pourbus" Adam and Eve, estimated at 2,000 to 3,000 Euro.

The work doesn't resemble the paintings by Pieter Pourbus really, and some searching shows that it is based on a work by Gillis Mostaert instead.

This engraving by Jan Sadeler (from the collections of the Victoria & Albert Museum) shows the same central element, and clearly attributes the "invention" of the composition to Gillis Mostaert. As both artists are almost contemporaneous, there is no reason to doubt this.

I don't know if the changes to format and the animals depicted within are due to the imagination of the copy-painter, or if a version existed with this format as well. It may even be that this is the actual original, there isn't much material to compare with (most extant Mostaert paintings are rather different busy city or village views). The work for sale certainly is good, but probably not good enough to be an original.

Even so, it should not have any trouble getting the estimate if people see it for what it is.
