At Christmas, 1749, Madame Denis had come to live with him. A plump widow of forty, not at all disinclined to try matrimony again, was Madame Denis by this time. She had attempted to be a playwright when Voltaire was at Lunéville; and her dear uncle had written with dreadful plainness of language to d’Argental that to write mediocre plays was the worst of careers for a man and “the height of degradation for a woman.”

Not the less, he saw his niece as a rule through very kindly spectacles, and let his good nature so far warp his judgment as to make him think, or at any rate say, that if she was no playwright she was an actress of the highest ability. It is true that she was very fond of that amusement, having a vast appetite for pleasure of any kind. At the beginning of the year 1750 both she and her sister, Madame de Fontaine, were in the Rue Traversière; and Madame Denis was making a very goodnatured, easy-going hostess for her uncle’s guests.

Voltaire had begun to go out and about again, too. It was at some very inferior amateur theatricals one night that he discovered an uncommonly good amateur actor: sent for him, and received the trembling and delighted youth the next morning. He embraced him, and thanked God for having created a person who could be moved, and moving, even in speaking such uncommonly bad verses. The pair drank chocolate together, mixed with coffee. Lekain—that was the youth’s obscure name—announced his intention of joining the King’s troupe. Voltaire offered to lend him ten thousand francs to start on his own account. Eventually, he received the young actor and his company into his house, and paid all his expenses for six months—“and since I have belonged to the stage I can prove that he has given me more than two thousand crowns,” says the famous Lekain in his “Memoirs.”

There was plenty of space in the house in the Rue Traversière now the Marquis du Châtelet no longer shared it. Voltaire turned the second floor into a theatre capable of holding a hundred and twenty persons, and in a very short time had there a playhouse, players, and plays which were the height of the mode and made Court and Comédie, with all their hopes pinned on poor old Crébillon of seventy-six, green with jealousy.

The Voltairian amateurs began with “Mahomet.” There were only half a-dozen intimates, and a few of the servants, as spectators. Lekain was in the title rôle, and the heroine was played by a shy little girl of fifteen, who—thanks, partly at least, to the energetic coaching of M. de Voltaire—became a pleasing actress. Actors and audience all stayed to supper; and, after it, M. de Voltaire produced the parts of “Rome Sauvée,” distributed them, and begged the actors to learn them as soon as they could. He coached and rehearsed his company himself. He superintended the scenery. He saw personally to the smallest details. Nothing was too much trouble if Voltaire could but outvie Crébillon, and “Rome Sauvée” “Catilina.” The audacious playwright actually had the coolness to make Richelieu get him the loan of the gorgeous costumes in which “Catilina” had been played at the Comédie.

“Rome Sauvée” appeared on the boards of the theatre of the Rue Traversière before an audience composed almost exclusively of the greatest literary men of the age and country. Here were d’Alembert, the prince of mathematicians, and, to be, perpetual secretary of the Academy; Hénault, President of the Chambre des Enquêtes, and of at least two of the most famous salons in Paris; young Marmontel, rising in the world; Diderot, the encyclopædist of unclean lips; gallant and accommodating friend Richelieu; and schoolmaster d’Olivet. The performance was a brilliant success. “Rome Sauvée” was worthy of its author.

At a second representation that untiring person himself played the part of Cicero, and excited the enthusiasm of the audience.

The fame and ability of the troupe of the Rue Traversière reached the ears of Court and Comédie of course. They had players as good; but where were they to find such plays?

One of the aims of the performance of “Rome Sauvée” in the Rue Traversière was attained when on February 28th, “after long hesitations,” that shifty Pompadour—a little bit to oblige Voltaire and chiefly because no other play so suitable could be found—had “Alzire” acted by a distinguished company of amateurs in the royal apartments.

Madame de Pompadour herself played “Alzire.” The Queen was not present; nor her daughters; nor the Dauphin; nor the playwright himself.
