That statue of Marsyas is a story from ancient mythology
“Apollo, of course, defeated Marsyas. He then exacted a savage punishment, exemplifying the jealous and petty nature of the Greek gods: he tied Marsyas to a tree and flayed him alive. It was said that Marsyas’ fellow woodland creatures wept a literal river for him”
It is not a real event and the story of having him tied to a tree is nothing like a death by impalement / crucifixion.
