I went to a Catholic secondary school and they were pretty big on the whole Easter thing. We got taught that historically, crucifixions were carried out by lashing the wrists of the victim to the horizontal board, which was then affixed to a stake to create the cross.
My understanding is that Jesus was nailed as well, out of spite. Given that his wrists were already lashed to the board, it doesn’t really matter where they nailed him.
Interestingly, when I was on my OE, I discovered that Easter Sunday was the day the everything shut down in the UK, vs Good Friday here (I know, Easter Sunday has restrictions too, but Good Friday is the big one here). I suspect this is because of the dominance of the Catholic Church during the European Colonisation phase of our history.
