Last quarter 18th C.

The English mechanic Michael Butterfield was appointed "Ingénieur du Roi pour les instruments de mathématique" in Paris. Although the sundials of the "Butterfield Type", named after this maker, were very popular in the late 18th century, their fine scales apparently made them somewhat difficult to use.
