The successor of Constantine, Leo IV., was significant only in that he followed his policy of persecution. He left the crown in 780 to his son Constantine and his widow Irene. Conspiracies, real or alleged, of his brothers were bitterly punished. The Empress Irene was satisfied so long as her son was still a boy to allow him a nominal share in the government; but when he grew up and showed an independent spirit, she used the growing unpopularity which came upon him after his repudiation of his wife to raise a party against him, and hired troops to take his life. He escaped death only to lose his eyes, and his wicked mother, surrounded by degraded favourites, reigned alone. It was she whom the great Teutonic King Charles was ready to wed, and the failure of the negotiations led, with other more notable causes, to the creation of the new empire of the West, so long held by German Cæsars, but professing still to be--as that of Constantinople historically was--the heir of the ancient empire of the Roman world. Wicked as Irene was, it was given to her to restore peace to the Church, and to reunite though only for a time the Catholic Church throughout the world. So completely was the popular feeling against the iconoclasts that it needed little of the intrigue or violence which Irene was so ready to use to secure the result she desired. In 786, when her worst passions had not been revealed and she still lived in union with her son, the seventh General Council met at Nicaea. It was attended by representatives from Italy as well as from the East, and as its decisions represent the use and teaching of the Eastern Church to-day, they may here be summarised in Professor Bury's words. "At the seventh sitting (5th or 6th October), the definition (ὅρος) of doctrine was drawn up; after a summary repetition of the chief points of theology established by previous Universal Councils, it is laid down that the figure of the holy cross and holy images, whether coloured or plain, whether consisting of stone or of any other material, may be represented on vessels, garment, walls or tables, in houses or on public roads; especially figures of Christ, the Virgin, angels, or holy men: such representations, it is observed, stimulate spectators to think of the originals, and, while they must not be adored with that worship which is only for God (λατρεία) deserve adoration (προσκύνησις)."[14]
