A modest burial site on which, a hundred years after the Apostle's martyrdom, a small funerary aedicule was built, commemorated by the presbyter Gaius at the end of the second century, as the historian Eusebius of Caesarea (Ecclesiastical History, 2, 25, 6-7) precisely reports. That aedicule, generally referred to as the 'Trophy of Gaius', indicated to early Christians the tomb of Peter, which, even before Constantine, was the destination of devout pilgrimages.
