Marten van Valckenborch or Gillis Van Conincxloo

Bremens & Belleville, from France, sells on 16 June 2019 an "Attributed to Marten van Valckenborch" Alexander and Diogenes, estimated at 5,000 to 7,000 Euro.

The RKD lists two other versions of this work, both attributed to & "Follower of Gillis Van Coninxloo II".

The first is a drawing in the British Museum, with some detail differences in the composition but basically showing the same work, but by a different hand.

The second work was sold at Tajan in 2008, according to the RKD. At first I thought it was this work (but cleaned) that reappeared at auction now, as it has the same dimensions (50 by 66 cm) and the same crack in the middle. However, closer inspection show some differences, e.g. in the castle at the right (more elegant in the Tajan version), or in the people directly to the left of the central tree, which can't be explained by cleaning only. So it looks as if these are two versions of this work by the same hand or workshop.
