Ornamentation of the Confessio for Ss. Peter and Paul

In keeping with our interest in what Msgr. Guido Marini is up to, some of our sharp eyed architecturalist readers picked up on this festal ornamentation of the confessio at the Basilica of St. Peter's for the June 29th Feast of Ss. Peter and Paul:

Apparently the ornaments include some rare marbles and one can see the statues of saints atop the two marble pillars, surrounded by two urns filled with what appear to be a variety of lilies.

The question was put out whether there has been such an arrangement seen in St. Peter's, not since the Council, but even since the 18th century?

I have no answer to this question, perhaps others of our readership might. At any rate, the image was worth sharing. [UPDATE: The answer is in. In point of fact, this very arrangement was seen in Piero Marini's time as well.]
