Their bodies are at Rome

A Treatise on Relics - John Calvin
(1870) - Project Gutenburg

"It is now time to speak of the apostles, and I shall begin with St Peter and St Paul. Their bodies are at Rome; one part of them in the church of St Peter, and the other in that of St Paul. We are told that St Sylvester weighed their bodies in order to divide them into equal parts. Both their heads are preserved also at Rome in St John of the Lateran. Besides the two bodies we have just mentioned, many of their bones are to be found elsewhere, as at Poitiers they have St Peter's jaw and beard. At Treves there are several bones of the two apostles. At Argenton in Berri they have St Paul's shoulder, and in almost every church dedicated to these apostles there will be found some of their relics. At the commencement of this treatise I mentioned that St Peter's brains, which were shown in this town (Geneva), were found on examination to be a piece of pumice stone, and I have no doubt that many of the bones considered to belong to these two apostles would turn out to be the bones of some animal."
