I picked this book up in a souvenir store just off St. Peter's Square in Rome in July since when our last trip to Rome we had been on Scavi tour of the excavations under St. Peter's Basilica, including St. Peter's tomb. The book was everything that I had hoped for – a thorough, heavily illustrated and diagrammed history of the excavations under the church. It explained the fall starts regarding what had been found, and what is known today – or more properly what was known 30 years ago when this book was released – about the bones that were found in the recess of the wall adjacent to the original grave.
I highly recommend it to anyone wanting to know more about the subject.
