"Adam and Eve": Jan Brueghel and Rottenhammer? Copy after Dürer

Brussels Art Auction sells on 22 Match 2016 a "Circle of Jan Brueghel and Hans Rottenhammer" Adam and Eve, oil on copper, estimated at 8,000 to 12,000 Euro.

It is a very good painting, but it looks to be older than Brueghel and Rottenhammer (which combination would mean about 1590-1620).

The origin is a print by Dürer from 1504, which is closely followed here.

The same pose (but different positions of the heads) was also used for an Adam and Eve by Jan Gossaert (from the Museo Thyssen Bornemisza in Madrid).

 It is not clear why the current work is given to the circle Brueghel and Rottenhammer, it seems to archaic for them and should be placed closer to 1520 than to 1590 probably. As it is an anonymous but good copy, it is probably worth closer to 5,000 Euros than the estimated 8,000 Euros.
