Apparently there's a thing going on in the ancient Aachen Cathedral about relics of one, yes, Saint Corona. This Saint Corona is supposed to be, yeah, you wouldn't believe it, the patron of surviving epidemics. Now I know there's catholic patrons for almost literally every single object, every single occupation and every single word and situation one can think of, but it's nearly impossible to find if this Saint Corona thing is actually true. It's easy to find her being patron of butchers and lumberjacks and stuff, but nothing about epidemics, even though pretty decent media (internationally) is mentioning it.
So, to catholics here, is there some sort of non-Wikipedia official list of who is patron of which object, thing, person, tree, situation, mountain or something where this could be verified?
