This can't be, yet it sure looks like Sylvester Stallone.

A visitor to the Vatican in Rome, saw what appears to resemble the likeness of "Rocky" in a painting  by artist Raphael, from the year 1511.

Check out the story and the likeness here.

From what I can see of the original painting, the Stallone likeness at least isn't wearing his "Rocky" sweats .

Back in the 1500's, I suppose if the Pope ever needed a bodyguard, perhaps he wouldn't have had to look very far. "Yo!"
