Description
Drawing instruments have been extensively used throughout the history of mathematics. Sets like this containing sectors, rules and compasses are still in wide use today as tools for technical drawing. Mathematics was a popular pastime among high society in the 18th century and this French tortoiseshell set with silver instruments was probably made for a wealthy gentleman.
