Nouveaux Ornemans D'Arquebuseries. Culture: French, Paris. Dimensions: 10 1/4 x 6 3/4 in. (26 x 17.1 cm). Engraver: Gilles Demarteau (French, Liège 1722-1776 Paris). Date: ca. 1750-55.Demarteau, the son of a Liege gunsmith, was apprenticed under the Parisian engraver De Lacollombe, who is known chiefly for his designs for firearms ornament. These prints, part of a set of nineteen, come from Demarteau's only pattern book devoted solely to firearms decoration. From the 1750s onward, Demarteau established himself as one of the most successful engravers of his generation and was renowned for perfecting the technique en manière de crayon, which allowed prints to simulate the appearance and subtlety of chalk drawings.
