The legates were honourably received in the capital and lodged in the Placidia Palace. After their arrival on the 10th September, 680, the emperor invited the patriarch George, of Constantinople, and through him Makarius, of Antioch, to call to council the metropolitans subject to them. At first the court had not thought of the sees of Alexandria and Jerusalem, which were under Saracen domination. But before the Council entered on deliberation two regular priests, Peter and George, were found, the first to represent Alexandria, the last to stand in the place of Theodore, vicar of the patriarchate of Jerusalem. It would seem that it was as well through this representation of the other sees, as also because of what Pope Agatho had done, that the Council which now met, though it had not been the original purpose of the emperor, from its beginning was marked as ecumenical, and afterwards took rank as the Sixth of these with the Five preceding. The Council was held from the 7th November, 680, to the 16th September, 681, in the hall called the Dome of the Imperial Palace, under the presidency of the papal legates and the imperial presidency of honour. The Emperor, with many officers of State, was present at the first eleven sessions, and with them directed the external order of business; but both he and they were carefully distinguished from the members of the Council, whose numbers did not at first reach a hundred, but afterwards rose to 174. In the first session, the 7th September, the Roman deputies, in an address to the emperor, desired that those who represented the Byzantine Church would declare the origin of the innovation which had existed in it for more than forty years. Macarius and his associates appealed to the earlier General Councils and to the Fathers. Thereupon the acts of the Council of Ephesus were read. There was found in them nothing in favour of the Monothelites, for the words of Cyril, that the will of Christ was almighty, could only be referred to His divine nature. In the second session, on the 10th November, the acts of the Council of Chalcedon were read, which were entirely unfavourable to the heresy. Macarius in vain attempted to insist on the words “theandric operation” without determining their meaning. On the reading the acts of the Fifth Council, at the third sitting, the 13th November, the writing of Mennas to Vigilius and two alleged letters of the latter were admitted to be spurious. The Monothelites could show nothing for themselves out of the General Councils. They had now to seek proof from the writings of the Fathers. They begged for time, and, on the proposition of George of Constantinople, the letters of Agatho and the Roman Council were ordered to be read, which occupied the fourth session, on the 15th November. In the fifth and sixth sessions, of the 7th December, 680, and the 12th February, 681, Macarius proposed passages from the writings of Fathers in behalf of his doctrine,
