Yesterday I mentioned the Bernini monstrance which was, as far as I know, given to the Basilica of Saints John and Paul by Pope Clement XIV. Here are some photographs, courtesy of Father Laurence Rywalt C.P.

Recently, an article in the Osservatore Romano wondered if the monstrance is actually by Bernini or by one of his pupils. You can make up your own mind on that one, because the scholars haven’t yet agreed.
