Eusebius says that

as soon as the emperor had spoken these words in the Latin tongue, which another interpreted, he gave permission to those who presided in the council to deliver their opinions. On this some began to accuse their neighbors, who defended themselves, and recriminated in their turn. In this manner numberless assertions were put forth by each party, and a violent controversy arose at the very commencement. Notwithstanding this, the emperor gave patient audience to all alike, and received every proposition with steadfast attention, and by occasionally assisting the argument of each party in turn, he gradually disposed even the most vehement disputants to a reconciliation.
