Another difficulty which gave the Pope much anxiety, and was not settled in the formalities of the coronation, was whether the Emperor should receive the crown from the hands of the Sovereign Pontiff. Pius VII. had brought up the question before leaving Rome, and Cardinal Consalvi had written on this matter, to which the Vatican attached great importance, as follows: "All the French Emperors, all those of Germany, who have been crowned by the Popes, have accepted the crown from them. The Holy Father, before undertaking this journey, requires to receive from Paris the assurance that there will be no innovation made in the present case, in the way of a diminution of the honor and dignity of the Sovereign Pontiff." At Rome only vague and dilatory answers had been received. In Paris the Emperor, leaving the matter to be decided on the spur of the moment, had only said: "I will arrange that myself." The preparations at Notre Dame had come to an end. They had been very considerable. Several houses that hid the north facade had been destroyed. Before the great entrance, still scarred by the ravages of the Revolutionists, there had been set up a decoration of painted wood, representing a vast Gothic porch with three arches upholding the statues of the thirty-six good cities, the mayors of which were to be present at the coronation. To the right and the left stood images of Clovis and Charlemagne, sceptre in hand. Above, between two golden eagles, appeared the Imperial coat-of-arms. This was intended for the sole entrance of the Pope and the Emperor. It was connected with the Archbishop's palace by large, covered, wooden galleries, adorned within by gobelin tapestry. This palace, to which Pius VII. and Napoleon were to go before they entered the Cathedral, no longer exists; it was destroyed, February 14, 1831, in an insurrection. It used to stand just by the side of the church. It was built in 1161 by Maurice de Sully, rebuilt in 1697 by the Cardinal of Noailles, embellished in 1750 by the Archbishop de Beaumont, and was the meeting-place of the Constituent Assembly from October 19 to November 9, 1789. There the Pope and the Emperor were to alight on their way from the Tuileries and put on their grand coronation robes before entering the Cathedral.
