This crossbow was made by François Aubert, a manufacturer specializing in the production of knives and crossbows. Active in Lunéville towards 1710-1740, he is mentioned in 1712 as gunsmith of the Duke of Lorraine. François-Etienne de Lorraine (1708-1765), Grand Duke of Tuscany, also appealed to the craftsman, especially during his marriage with the Archduchess Maria Theresa, future Empress of Austria.
Decorated with the coat of arms of Grand Duke of Tuscany, this crossbow is decorated with foliage motifs surrounding a wild boar. Reserved for hunting small game, the crossbow jalet appears in the sixteenth century. It allows to project balls of clay or lead. A pediment of sight generally facilitates the accuracy of the shot. The crossbow was used until the end of the 18th century, and therefore well after the generalization of the arquebuse: its silent character makes it possible to approach the game without scaring it.
