French-Style Sector Signed by Nicolas Bion

Description
This small, one-sided brass sector has two flat rectangular arms, hinged at one end. A flower decorates the hinge. The instrument has double scales of chords, running from 10 to 90, and of specific weights for five metals, marked with their symbols. The outer edge has a scale that runs from 1/4 to 33 and is labeled Pouts [sic] des boulets. The instrument is marked: N Bion (/) A –Paris. The signature is slightly different from the one on the other sector from Bion's workshop in the collection, 1985.0580.05.
Nicolas Bion (c. 1652–1733) made and sold mathematical instruments in Paris in his own shop and as royal maker for Louis XIV. He included a lengthy discussion of sectorial scales in his famous 1709 manual on the construction and use of mathematical instruments. Bion's son, Jean-Baptiste, took over the shop in 1731.
The Smithsonian acquired this sector in 1962 from Jacob (Jake) Zeitlin and Josephine Ver Brugge Zeitlin, who operated a rare books store for over 40 years in West Hollywood, Calif.
