So according to Christian mythology, the story goes that Roman soldiers decided to create a 'crown of thorns' to humiliate Jesus for being a 'king of jews'.
While this obviously is religious scripture and so most likely some kind of allegory, what I'm wondering is - did people in the ancient Roman period ever actually do things like this to people who were crucified? Humiliate them further by dressing them up in certain ways, or perhaps degrade them with humiliating acts, or other things of that sort?
I actually wrote about the Roman practice of executing people in humiliating costumes just a couple weeks ago, as part of my answer to the question of whether executions were a part of theatrical plays in Rome! The scholars I cite think that if the "crown of thorns" (also the purple cloak and possibly a reed scepter) is real, then it is an example of the same phenomenon, though in a less spectacular context. Here's the post.
