A fine brass sector by Pierre Le Maire II dating to circa 1735. Features nine scales including lines, chords, solids, metals, equal parts, polygons, planes, diameter and weight of bullets, and gun calibers. Alchemical metal symbols include gold, lead, silver, copper, Iron and tin. The signature is followed by the flourish typical of French instruments made before 1740. Hinge is engraved with a fine acanthus rosette. Superb example in fine condition.

Pierre le Maire II (1717-1785) worked between 1730 and 1760 in Paris at the sign au Nouveau Quartier Anglais on the Quai de l’Horloge, Ile de la Cite. He was the son of Pierre le Maire 1 (1672-1745) and signed his instruments Le Maire fils until 1744. His uncle was instrument maker Jaques le Maire (worked 1714-1762). Pierre le Maire II was the first maker in France to produce the Hadley’s quadrant, which gave meaning to his shop sign au Nouveau Quartier Anglais. He also made sundials, surveying instruments, mathematical instruments, and very fine drawing instruments. Le Maire was a member of the Founders Company, serving as a juror of masters 1751-53. He was also Ingenieur du Roy (Engineer to the King) and made instruments for members of the Academie des Sciences including standard measures for the city of Paris. The final image in the image gallery (adapted from P. Rocca 2012 p. 33) beautifully illustrates the signatures of the Le Maire family and their associated dates.
