This might be a really obvious question, but Google hasn't helped (much) with it. When we visited St. Paul's Cathedral in Mdina earlier today, I noticed that a lot of the marble tombstones on the floor had pictures of two hats on them. One of the hats was a mitre, and the other was a black hat with a wide flat brim (often with braided cords hanging from it) - I think the latter might be called a cappello romano? Does that mean that the person honored there was both a priest and then a cardinal? Is there an significance to the braided cords?
I know that this isn't a typical tourist question, but I'm still hoping one of the Malta experts on here knows the answer! Thanks!
