Origin of two paintings?

[Jona Lendering]

I agree. For a while, I thought it was a representation of the story of Saint Paul, but he was not a soldier.

Constantine? Even though the Milvian Bridge isn't visible and JC actually goes to him, the image of JC sleeping might be symbolic of him not being the main religion. A priest could explain that to the viewer as a commentary?

I ahve been thinking about Constantine too, although I think it is not JC sleeping but Pope Sylvester. There was a medieval legend that Constantine converted because he was cured from a disease. However, that disease was some sort of leprosity, not an epileptic disorder. I would also expect Constantine on a throne or something, not discussing with his fellow soldiers.
