The Maria are also one of my favorite, I have some small article about them but unfortunately in Hungarian, but I will try to explain som coin here soon...
Joe, They are (recent) favorites of mine, too (my favorites shift from time to time as I
work on them). I'd love to see the article, even if I will have difficulty translating it. You have my email address. I'd much appreciate a copy. And any explanations that you have time to post here in English will be enthusiastically received.
