BAPTISMAL FONT, C2 CE AND 1692-1698.
ST PETER'S
This huge porphyry basin has a somewhat mysterious original use. Often said to have come from the tomb of Hadrian, it is disproportionate for a burial that was probably cinerary. It emerges into history as spolia in 983, when it was used as the top of the monument of the emperor Otto III in the atrium of Old St Peter's. The marble sarcophagus was set into the floor, and the monument above it was distinguished by the imperial purple of the lid. In 1612, when Paul V Borghese was demolishing the Constantinian atrium, he did away with the monument and the tomb entirely. The porphyry lid was broken and put into storage. Finally in 1692 Innocent XII Pignatelli decided to turn the lid over again and make it the baptismal font of St Peter's, set partially into the floor in memory of the palaeochristian practice of full-immersion baptism. The artificer of this project, Carlo Fontana, published a self-congratulatory volume about it, describing how he had put the pieces back together and "brought [the font] to perfection despite the many contrary factors encountered".
#SpoliaSunday this week takes us to the #Vatican, where we can admire a large #spolia #porphyry basin that serves at the #baptismal #font of St Peter's. And it replaced another spolia font! 🧵
