Can you spot Judas in the picture ? Details matter .

But what about the man with the knife, pointing to the neck of Maria?

I don’t see anyone pointing a knife at Mary only fingers.

'5th' man in, with halo, on left-hand side of painting, with his head closest to Miriam/Mary ..his forest green arm sleeve clutching a knife with his right hand behind his back, while his left hand is visible about to touch Miriams/Mary) throat. Judas is sitting next to Miriam/Mary.

I just do not see a knife.

Copy, Paste pix to word doc. orientate to landscape. and enlarge pix

Found the knIfe

if your talking about the man sitting next to Mary that is a bag of 30 silver coins. Red tee shirt and blue rob. That is Judas and he does not have a halo.

I tried to outline the knife. Its not being held by Judas. It is in the Right Hand of Peter( I think). He is the man between Judas and Mary. His right hand is behind Judas. It has a knife in it.
