In the summer of 64, fire swept through Rome and burned for days. Rumor blamed the Emperor Nero himself. To deflect suspicion, the Roman historian Tacitus records, Nero fixed the guilt on the Christians — a group already disliked — and subjected them to punishments of appalling cruelty.
This was the first time the Roman state, rather than a local mob or a synagogue, turned its power against the Church. It would not be the last. Over the next two and a half centuries, persecution would come and go with the temper of emperors.
Christian tradition holds that both Peter and Paul died at Rome in or around this persecution — Peter crucified, Paul beheaded. The blood of the martyrs, Tertullian would later write, became the seed of the Church.
