The result of the interview proved that Madame Duronceray had not exaggerated her daughter's talents. As actress, singer, and dancer, the girl showed remarkable promise, while she was as charming as she was accomplished.[120] A very brief examination sufficed to assure Favart that he had discovered a most valuable acquisition to his troupe; and it was at once arranged that Mlle. Chantilly, as Justine had decided to call herself, out of deference for a branch of the Duronceray family which lived in Paris and might conceivably have taken umbrage at one of their name appearing on the stage, should make her _début_ in a piece from Favart's own pen, which he was then writing, in celebration of the approaching marriage of the Dauphin with the Infanta Maria Theresa. The title of this vaudeville, _Les Fêtes publiques_, has alone come down to us; but, whatever its merits may have been, it was highly successful, the new actress's piquant beauty and grace, no less than her vocal and dramatic talents, being loudly acclaimed by a succession of crowded houses. The charms of Justine had already made a deep impression upon Favart, and, after her triumph in _Les Fêtes publiques_, he became so deeply in love with the fair _débutante_ that he declared his passion, which the young lady was pleased to reciprocate. An honest and excellent man, Favart did not attempt to take advantage of their respective positions,[121] but offered to make her his wife; and, on December 12, 1745, they were married at the Church of Saint-Pierre-aux-Bœufs, a little church generally patronised by persons who wished to keep their marriages secret for a while, in the presence of only the necessary witnesses. In view of what we shall presently relate, it is important to note that M. Duronceray, Justine's father, was not present at the ceremony, although he had given the required consent to his daughter's marriage, in writing. The marriage took place under very inauspicious circumstances. The vogue that Favart by his operas and Justine by her singing and acting had obtained for the Opéra-Comique had aroused the jealousy of the Théâtre-Français and the Comédie-Italienne; and, in the autumn of 1745, they solicited and obtained its suppression. The severity of this measure was somewhat mitigated by the permission which Favart received to open a theatre at the Fair of Saint-Laurent, whither he transferred his company, and presented, among other pieces, a pantomime, entitled _Les Vendanges de Tempé_, of which the success was assured by the charming acting of Justine. This privilege, however, was only accorded him for a very short time, with the object of allowing the troupe of the Opéra-Comique leisure to make other arrangements, and, on its withdrawal, Favart and his colleagues found themselves in a very embarrassing situation; and matters must have gone hardly with them, had not the poet had the good fortune to find a protector as powerful as he was unexpected.
