The Synod of Ancyra was an ecclesiastical council, or synod, convened in Ancyra (modern-day Ankara, the capital of Turkey), the seat of the Roman administration for the province of Galatia, in 314. The season was soon after Easter; the year may be safely deduced from the fact that the first nine canons are intended to repair havoc wreaked in the church by persecution, which ceased after the overthrow of Maximinus II in 313.^[1] Only about a dozen bishops were present, nonetheless representing nearly every part of Syria and Asia Minor. Either Vitalis, Bishop of Antioch, or Marcellus of Ancyra presided, and possibly both were present, although the Libellus Synodicus, also known as the Synodicon Vetus, assigns to the latter.^[2]
