A very rare French triangular compass or divider dating from the end of the 18 century. This divider is made of ornate steel typical of the period. The addition of a third arm made it possible to use the device to fix three points simultaneously on a plan and to transfer them together to another drawing, thereby determining the lengths of lines and their orientations in one operation.
