In 920, he was asked by the Byzantine Emperors Romanos I and Constantine VII and the Patriarch of Constantinople Nicholas Mystikos to send some legates to Constantinople to confirm the acts of a synod which condemned fourth marriages ( a legacy of the conflict which embroiled Constantine ’ s father Leo VI the Wise ) thereby ending a schism between the two churches.
