Not what you think, though. James Whitaker of Whitaker Studios in the UK has an amusing little story:
As we walked down the street to where I wanted to take the portrait Paul started to explain to me the origin of the halo. He explained that back in the day sculptors started to add disks above the heads of their famous subjects to prevent their face from becoming awash with bird poo. With time this purpose was forgotten and the discs were simply associated with important people, and then in turn saints.
Now, a lot of my knowledge comes from stories like this. Often the stories are told to me in the pub where alcohol may have been consumed. Despite the world wide web being on my phone, in my pocket, I don’t fact check these things. Wikipedia is not consulted. Had I referred to Google I would have found countless articles about the origins of the halo, almost none of which refer to bird excrement. But then why let facts stand in the way of a good story?
Indeed. A thousands lies can tell a truth. Although what it might be in this case, I’m not sure.
