The Marquis de Cypierre was an amateur painter who collected many important works of art. Some of his purchases were made under the advice of Théophile Thoré, and included mostly paintings by eighteenth century masters, such as Watteau. A sale of his collection was held in Paris on 10 March 1845 and days following.
