"The Conspirators", by General Lew Wallace

[STS Lincolnite]

If I recall, when Wallace was alive, the painting sat on an easel in one corner of the study - I think there is a photograph of Wallace in his study where the painting can be seen. I will see if I can track down the photo I am thinking of. The painting is currently displayed in the study about 10 feet off the ground above a bookcase. It was decided to display it there because if on the floor where it had been historically displayed, it would undoubtedly be touched and grabbed, etc. and would be at greater risk for damage.

Per previous posts/comments, I would also think that the size of the painting itself may be symbolic. Maybe the scale was such that it was metaphor for the scale of the event itself.
