I have been to see the Baroque exhibition at the V & A; I hope shortly to do a post on the gross ignorance on show in the labelling of the ecclesiastical items and in the glossibuch that goes with the exhibition. But briefly ...
... the book has picture of a stole made in Rome (part of a sumptuous commission from the King's Majesty of Portugal) in the middle of the 18th century; it seems to show three ribbons attached to the stole, each with an exotic bobble at the bottom of it. One ribbon is affixed to the middle of the stole; the other two some way down each of the ends.
Does this mean that the stole was worn with the midpoint, where the cross is, well down the back, and with a ribbon securing it to the girdle? My old edition of O'Connell says that auhorities differ about how far down the back the stole should go, and I believe sometimes it was, if long enough, tucked into the girdle. There is a photograph of Fr Hope Patten vesting for Mass in the Sacristy at Walsingham, and with the stole a long way down his back.
I habitually wear the stole like this; but it does leave the stole at risk of slipping off one's collar bone and down one's shoulders. Perhaps the other two, shorter, ribbons are to prevent that?
