Not all painting of Biblical stories are completely accurate. I saw in a museum a picture of the Last Supper. And there on the table was rabbit waiting to be eaten. I laughed.
But my guess of the Good Samaritan is that, just a guess, but if you look at the faces of the men it shows the feelings that are described in the parable.
Not the feelings that are ascribed to the religious men in the parable - they ignored the injured man.
Your guess just doesn’t fit any of the specific details shown in the picture. It’s not just inaccurate, it’s exactly the opposite of the premise of the parable.
I took about an hour and skimmed through the State Hermitage Museum site, just to get a feel of the art from the Renaissance, and after looking at a few hundred pics, I have a feeling that this drawing in question is much more recent. There are some pictures of monks, but not anything close to what was in the drawing, but nonetheless, very interesting to look at…especially biblical depictions with Renaissance attire in some of them…The Wedding at Cana.
I sent a link to this thread to four stalwart Catholic friends of mine, and none of them recognized the picture.
Why? Because rabbit isn’t kosher? Or because of the presence of meat? Or some other reason?
Rabbit isn’t kosher, there is no way it would be at the table.
The seated figure doodled on the back seems to me to be an attempt at drawing Queen Victoria in her later years.
Nah, I think it’s based on either Raphael’s or Greco’s portraits of popes, or (the drawing style looks 20th century, but impossible to tell how recent exactly) Francis Bacon’s pope.
