A correspondent has forwarded to me the above photo of Pope Gregory XVI wearing the red velvet Papal Cappa. This was used by the Supreme Pontiff for Tenebrae and Christmas night. The picture was found by Leo at The Far Sight.
I was told that this papal cappa was abolished by the next Pope, none other than the Blessed Pius IX. This has me worried. Did Mastai-Ferretti harbour secret yearnings for guitar masses some time in the future? I think we should be told.
