Stonemason’s Compass, Goldenberg, Cast Steel, France, Early 20th Century

A stonemason’s or stone-setting compass made of cast steel, marked with an eye and the inscription “Goldenberg Acier fondu”; the company was founded by Gustave Goldenberg during the 19th century. In perfect condition, with a beautiful patina from use. Early 20th-century item, from 1930 at the latest.

“The stonemason’s compass consists of two rulers hinged at one end and fitted with steel tips at the other two ends. Both legs are flat over two-thirds of their length. One of the legs is double-walled, thus forming, when closed, a compartment for the other. The arms are tipped with sharp points. Stonemasons use it to set perpendiculars, draw blueprints, measure angular openings, etc. It is called a “stone-setting” square because it allows for the preparation and guidance of stone block installation in construction and for performing the same tasks on structural timber. The stonemason is the worker who marks out the stone cuts according to the plans. »
