**Do we know how many bishops attending the Council of Nicaea were actual victims of the Roman perscutions?** The Council of Nicaea opened on May 20, 325 AD. > The First Council of Nicaea, the first general council in the history of the Church, was convened by the Roman Emperor Constantine the Great upon the recommendations of a synod led by Bishop Hosius of Corduba in the Eastertide of 325, or rather convened by Hosius and supported by Constantine. > > Constantine had invited all 1,800 bishops of the Christian church within the Roman Empire (about 1,000 in the East and 800 in the West), but a smaller and unknown number attended. Eusebius of Caesarea counted more than 250, Athanasius of Alexandria counted 318, and Eustathius of Antioch estimated "about 270" (all three were present at the Council). Later, Socrates Scholasticus recorded more than 300, and Evagrius, Hilary of Poitiers, Jerome, Dionysius Exiguus, and Rufinus each recorded 318. This number 318 is preserved in the liturgies of the Eastern Orthodox Church and the Coptic Orthodox Church. - [First Council of Nicaea](https://en.m.wikipedia.org/wiki/First_Council_of_Nicaea) The Roman perscutions ended with the Edict of Milan in February 313 AD. Do we know how many of the bishops, who attended the Council of Nicaea were persecuted by Roman authorities prior to 313 AD? Someone once told me that some of the bishops who attended the Council had been previously tortured and even mutilated in the Roman Persecutions. There is simply 12 years between the two!
