FELIS RESPICIENS
Few tree crucifixions. Being bound to a tree may sound not very terrific but in fact it is the same starving naked on display waiting for wild dogs or wolves as when you're bound to the low cross.
Just as horrific. If I was in a raiding party, the last thing on my mind would be creating a cross from sawn timber. Use a tree, a barn door, the timbering of a house. Use nails if you can find any, otherwise rope or wire.
The fear factor for those surviving will be just as great.
