Julie d’Aubigny's Sabre

Origin
Julie d'Aubigny (1673–1707), better known as Mademoiselle Maupin or La Maupin, was a 17th-century swordswoman and opera singer. Her tumultuous career and flamboyant life was the subject of gossip and colorful stories in her own time, and inspired numerous portrayals afterwards. These included running from the law with her teacher Sérannes, dressing in men’s clothing without concealing her gender, found several lovers, participated in many (illegal) duels and eventually joined the opera later in life.
