When the Lenoncourt family, living at Givry, an estate not far from this farm, heard of the arrival of the Comte de Mortsauf, the Duc de Lenoncourt invited him to stay at Givry while a house was being prepared for him. The Lenoncourt family were nobly generous to him, and with them he remained some months, struggling to hide his sufferings during that first period of rest. The Lenoncourts had themselves lost an immense property. By birth Monsieur de Mortsauf was a suitable husband for their daughter. Mademoiselle de Lenoncourt, instead of rejecting a marriage with a feeble and worn-out man of thirty-five, seemed satisfied to accept it. It gave her the opportunity of living with her aunt, the Duchesse de Verneuil, sister of the Prince de Blamont-Chauvry, who was like a mother to her.
Madame de Verneuil, the intimate friend of the Duchesse de Bourbon, was a member of the devout society of which Monsieur Saint-Martin (born in Touraine and called the Philosopher of Mystery) was the soul. The disciples of this philosopher practised the virtues taught them by the lofty doctrines of mystical illumination. These doctrines hold the key to worlds divine; they explain existence by reincarnations through which the human spirit rises to its sublime destiny; they liberate duty from its legal degradation, enable the soul to meet the trials of life with the unalterable serenity of the Quaker, ordain contempt for the sufferings of this life, and inspire a fostering care of that angel within us who allies us to the divine. It is stoicism with an immortal future. Active prayer and pure love are the elements of this faith, which is born of the Roman Church but returns to the Christianity of the primitive faith. Mademoiselle de Lenoncourt remained, however, in the Catholic communion, to which her aunt was equally bound. Cruelly tried by revolutionary horrors, the Duchesse de Verneuil acquired in the last years of her life a halo of passionate piety, which, to use the phraseology of Saint-Martin, shed the light of celestial love and the chrism of inward joy upon the soul of her cherished niece.
