Not familiar with the subject and two solutions but still a great puzzle. Really enjoyed it.

Thank You.

One of my favorite pieces of classical art, great job!

Murdered in his bath. Thank You very enjoyable.

Hint: Start with: R1/C3-6
Last four ambigious, but easily guessable. Nice puzzle. Thanks.

Nice, thanks for the hint Rudi.

No hint required, just the last 2 need to be guessed.

Thank You.^__^.

Thanks.

The hint might have made it quicker but not needed.
Looked up the painting after I'd finished and learnt about art.
Very nice representation, thanks.

Bien rendu !
