Leo I the Thracian
Abila Lysaniae, which was in the Roman province of Phoenicia Secunda, was also a Christian bishopric. The Coptic version of the acts of the First Council of Nicaea includes a Heliconius of this see among the participants. Iordanus was at the 445 Council of Antioch and at the Council of Chalcedon of 451. John was one of the signatories of a joint letter that the bishops of Phoenicia Secunda sent in 458 to Byzantine Emperor Leo I the Thracian to protest at the killing of Proterius of Alexandria. Alexander was deposed by Emperor Justin I in 518 for his Syriac Orthodox tendencies.
