I like very much your pictures of the piscatory ring of H.H. Pope Benedikt XVI. It is really a wonderful piece. Have a look at my pictures and research.
This information comes from the forum of the Pope Bendict XVI fan club. http://theratzingerforum.yuku.com/sreply/4229/t/Papal-clothing-and-liturgical-practices.htmlThe close up pictures of the ring have a request that they should not be copied!
Anonymous is right!The source was mentioned in the footnote but not very clearly. I changed this. Now it is marked clearly below the headline.
