I feel it is a genuine Burne-Jones for the following reasons: 1. A copy always has hesitation and there is none of this in the drawing. 2. The shading and the fleshly portrayal of the bodies is totally convincing. 3. The head of the figure against the floor is similar to heads of the mid to late 1860s. 4. The foreshortening of the upper male's head is economic and very well drawn. 5. The only argument for it being a copy could be that there are strong outlines in some parts but Burne-Jones was doing this in the early 1870s. 6. There is no painting in existence that includes the horizontal figure and I suggest that the Liverpool oil with only the upper figure is the work of an assistant (with overpainting by the master) told by B-J to copy it from this drawing. B-J had decided not to include the lower figure. Of course I have not seen the original as of 20/12/2023.
