Contemporary of the portrait paints by Louis Michel Van Loo in 1769, our miniature shows Louis III Phélypeaux, count de Saint Florentin, marquess then duke de La Vrillière (1705-1777), Secretary of Louis XV.

The statesman is represented sat to his desk, raising the order Holy Spirit.

The count de Saint Florentin then duke de La Vrillière, inherited from his father the responsibility of Secretary of the corporate affairs of the reformed claimed religion ( 1725 ), what did not prevent him from being received freemason in 1735. Minister of State of 1761 à1775, he detains the record of ministerial longevity; specialist of the letter de cachet, he had to resign in 1775 because of the abuse which he had made. Saint Florentin was a victim of an accident of hunting in 1765, at the end of which he was amputated  of the left hand, what explains that this one is hidden in this portrait. He was made a silver prosthesis.

In 2011, Jean-François Parot, in his novel " Le crime de l'hôtel de Saint-Florentin ", ressussite the minister  and his silver hand , in his Hôtel particulier of Saint Florentin's street in Paris.
