Who is Judas in this painting?

Thanks Penn Guinn.  That's interesting!   I hear talks about this painting all the time,  they point out different people though.   The one you chose,  and the one seated with

his back to us.  (He has a money pouch on his belt)   

Lol @quiz.  No I'm really interested  Wow about the wiki link!   Thanks,  but the moneybag makes sense too since Jesus put Judas in charge of it.   It's easier to see in the real painting,  but you can kind of see a small pouch on the right side of his belt.  Being the only one with his back to us makes sense too,  the figure on the far left has a peaceful stance,  not like 'Judas' (if)  and the other character goofing about. 

hmmm 

thanks Vegas,  I think I'm more convinced now,  the one with his back to us doesn't have a halo.   hmmm

Yes,  probably the smallest halo though.   Christ is the only one with a halo in the OP.   You can see a tiny bulge under the belt on the right side of Judas (?),  but it's much more obvious in the real painting,
and it's a lighter colour,  not blue.  In a way it makes sense that he's the only one that turns his back to us;  as he turned his back to Jesus.   It's a volunteer at the gallery I frequent that say Judas is the one on the floor,   a staff member that does frequent talks says he's on the far left.  I might mention my concerns if I ever see him again,  LOL.  Anyway,  Tintoretto isn't here to ask,  so maybe the question isn't answerable,  but it's been fun chatting with you about it.  Thanks!    

Well the dog is front and center in both paintings.  "symbols of fidelity, faithfulness, protection, wealth, and unconditional love"


I've heard some cultures are not fond of dogs because they are thought of as not clean,  (generally speaking!)
