Regret I do not recollect the particular section of the museum.
However , I can email a 'photo I took of the picture.
I have it noted as a 'mural' but I am not sure.
If it is part of a larger work then it is very well composed !
It is in a sequence just before Raphael's works 'Battle of Milvain Bridge' , 'School of Athens' etc , whilst following the tortuous route to the Sistine Chapel.
That's all I'm afraid
