Speaking personally, there is always something I find particularly enchanting and inspiring about small, traditional country shrines and chapels -- and all the moreso when they are being used within the context of the usus antiquior or reform of the reform.
In this instance, the Mass was being offered in the usus antiquior in memory of Abbé Franck-Marie Quoëx who was particularly known within French and Italian speaking Europe as an excellent Master of Ceremonies and liturgist.
The chapel is the Barbarano chapel north of Rome and John tells us that "the private chapel was constructed in the nineteenth century and is located on the old estate of a bishop's summer villa, hunting acreage and hobby farm."
Please say a prayer for the repose of the soul of Abbé Franck-Marie Quoëx.
