A negotiation for the success of which both parties were equally anxious did not require a long time for its conclusion; and by the beginning of July, 1769, all the preliminaries were arranged; the French newspapers were authorized to allude to the marriage, and to speak of the diligence with which preparations for it were being made in both countries; those in which the French king took the greatest interest being the building of some carriages of extraordinary magnificence, to receive the archduchess as soon as she should have arrived on French ground; while those which were being made in Germany indicated a more elementary state of civilization, as the first requisite appeared to be to put the roads between Vienna and the frontier in a state of repair, to prevent the journey from being too fatiguing.
By the spring of the next year all the necessary preparations had been completed; and on the evening of the 10th of April, 1770, a grand court was held in the Palace of Vienna.

Through a double row of guards of the palace, of body-guards, and of a still more select guard, composed wholly of nobles, M.de Durfort was conducted into the presence of the Emperor Joseph II., and of his widowed mother, the Empress-queen, still, though only dowager-empress, the independent sovereign of her own hereditary dominions; and to both he proffered, on the part of the King of France, a formal request for the hand of the Archduchess Marie Antoinette for the dauphin.

When the Emperor and Empress had given their gracious consent to the demand, the archduchess herself was summoned to the hall and informed of the proposal which had been made, and of the approval which her mother and her brother had announced; while, to incline her also to regard it with equal favor, the embassador presented her with a letter from her intended husband, and with his miniature, which she at once hung round her neck.

After which, the whole party adjourned to the private theatre of the palace to witness the performance of a French play, "The Confident Mother" of Marivaux, the title of which, so emblematic of the feelings of Maria Teresa, may probably have procured it the honor of selection.
The next day the young princess executed a formal renunciation of all right of succession to any part of her mother's dominions which might at any time devolve on her; though the number of her brothers and elder sisters rendered any such occurrence in the highest degree improbable, and though one conspicuous precedent in the history of both countries had, within the memory of persons still living, proved the worthlessness of such renunciations.[1] A few days were then devoted to appropriate festivities.

That which is most especially mentioned by the chroniclers of the court being, in accordance with the prevailing taste of the time, a grand masked ball,[2] for which a saloon four hundred feet long had been expressly constructed.
