Do you know the name of this painting?

Question

It looks like a renaissance painting of a saintly figure with a knife stuck in his head in a very slapstick kind of way, but I believe the painting is actually from the renaissance era.

If I'm not mistaken, there is a series of these paintings, and I saw a glimpse of them in an art history course and loved them, but haven't gotten a hold of the professor to ask him for the name of the painting and artist's name...I need a print of this thing on my wall :)

Thanks!

Answer 1

Is this it?

Pedro de Berruguete - Saint Peter the Martyr

or this: Bergognone - St. Peter with a Kneeling Donor http://www.artcyclopedia.com/feature-2000-11-bergognone.html

Answer 2

seems like i saw such a painting in a show titled "copper as canvas" a series of paintings from the renaissance period done on copper plates, treated and painted on with oil.
there is a book titled copper as canvas, i just tried to find it with the little searcher in the corner and came up with zero, but at least that is a place to start...also look up anything that may have shown in the nelson adkins museum in kansas city in the last ten years...i know i've seen that painting there.
