The Bishops present included Secundus of Tigisis, Donatus of Mascula, Marinus of Aquae Tibilitanae, Donutus of Calama, Purpurius of Limata, Victor of Garbis, Felix of Rotarium, Nabor of Centurio, Silvanus, and Secundus the younger.
Secundus was known to be opposed to the consecration of traditors, or bishops who had turned over the Scriptures to the Romans during the Diocletianic Persecution.
Following the meeting, Mensurius, the Bishop of Carthage, wrote to Secundus to explain his actions during the persecution, claiming that he had only handed over heretical works.
Even though the officials asked for more, the proconsul of the province had refused to search the Bishop's private home.
Secundus responded without directly blaming Mensurius, but he pointedly praised the martyrs in his own province who had been tortured and put to death for refusing to surrender the Scriptures, and mentioned that he himself replied to the officials who asked him for the Scriptures: "I am a Christian and a bishop, not a traditor."
The Donatists appealed to Emperor Constantine, who asked Pope Miltiades to oversee a hearing with three neutral bishops.
Donatus and Secundus refused to recant, and Donatism continued to be popular among Berbers in North Africa until the arrival of Islam.
