And here is a late Medieval one by a less-well-known French painter Jean Fouquet (Paul's Conversion). Less emotional, but still full of symbolism. And Saul's horse is ever present. I couldn't find detailed information on it, but I think it is part of an illuminated manuscript, with the curved writing at the top, and the simple formality of its design.
