This is approximately of the same size as the painting (still no image found) that was in possession of sir Samuel Gluckstein in London and in 1974 auctioned at Christies in London (Unverfehrt), but turns out already in 1924 in possession of the Museum (wikimedia) from Claude Philips in London.
Moreover, this painting in Glasgow not mentioned in the book of Unverfehrt.

Signed lower right: ‘jhieronimus bosche’. Partly similar to the compositions of followers who are located in Tallinn and Copenhagen and in in a private collection at an auction at Sotheby's in London in 2009.
