during excavations around the Basilica of Saint Paul Outside the Walls on the Via Ostiensis. Vatican archaeologists declared this to be the tomb of Paul the Apostle in 2005. In June 2009, Pope Benedict XVI announced excavation results concerning the tomb. The sarcophagus was not opened but was examined by means of a probe, which revealed pieces of incense, purple and blue linen, and small bone fragments. The bone was radiocarbon-dated to the 1st or 2nd century. According to the Vatican, these findings support the conclusion that the tomb is Paul's. Church tradition Various Christian writers have suggested more details about Paul's life. 1 Clement, a letter written by the Roman bishop Clement of Rome around the year 90, reports this about Paul: Commenting on this passage, Raymond Brown writes that while it "does not explicitly say" that Paul was martyred in Rome, "such a martyrdom is the most reasonable interpretation". Eusebius of Caesarea, who wrote in the 4th century, states that Paul was beheaded in the reign of the Roman Emperor Nero. This event has been dated either to the year 64 AD, when Rome was devastated by a fire, or a few years later, to 67 AD. According to one tradition, the church of San Paolo alle Tre Fontane marks the place of Paul's execution. A Roman Catholic liturgical solemnity of Peter and Paul, celebrated on 29 June, commemorates his martyrdom, and reflects a tradition (preserved by Eusebius) that Peter and Paul were martyred at the same time. The Roman liturgical calendar for the following day now remembers all Christians martyred in these early persecutions; formerly, 30 June was the feast day for St. Paul. Persons or religious orders with a special affinity for St. Paul can still celebrate their patron on 30 June. The apocryphal Acts of Paul and the apocryphal Acts of Peter suggest that Paul survived Rome and traveled further west. Some think that Paul could have revisited Greece and Asia Minor after his trip to Spain, and might then have been arrested in Troas, and taken to Rome and executed. A tradition holds that Paul was interred with Saint Peter by the via Appia until moved to what is now the Basilica of Saint Paul Outside the Walls in Rome. Bede, in his Ecclesiastical History, writes that Pope Vitalian in 665 gave Paul's relics (including a cross made from his prison chains) from the
