One of the most notable instances of persecution during the reign of Aurelius occurred in 177 at Lugdunum (present-day Lyons, France), where the Sanctuary of the Three Gauls had been established by Augustus in the late 1st century BC. The persecution in Lyons started as an unofficial movement to ostracize Christians from public spaces such as the market and the baths, but eventually resulted in official action. Christians were arrested, tried in the forum, and subsequently imprisoned. They were condemned to various punishments: being fed to the beasts, torture, and the poor living conditions of imprisonment. Slaves belonging to Christians testified that their masters participated in incest and cannibalism. Barnes cites this persecution as the "one example of suspected Christians being punished even after apostasy." Eusebius says that in 177, Irenaeus had been sent with a letter, from certain members of the Church of Lyons awaiting martyrdom, to Pope Eleutherius; Ireneaus does not mention the persecution in his "Adversus Haereses". Eusebius writes of it in his "Ecclesiastical History", written about 120 years after the events. Gregory of Tours tells of it in his ""Liber in gloria martyrum"", or "Book of the Glories of the Martyrs". It deals almost exclusively with the miracles wrought in Gaul by the martyrs of the Roman persecutions.
