a detailed map of Scotland. It probably comes from the enlarged edition of Bonne's monumental atlas (1788). During this time, Rigobert Bonne held the title of Naval Hydrographer in France. Map shows towns, rivers, mountains, lakes, and a number of other details. Rigobert Bonne was born in the Ardennes at Raucourt on October 6, 1727. He learned mathematics without a teacher and became an engineer at eighteen. He served in this capacity in the Flanders War, participating in the siege of Berg-op-Zoom in 1747. He applied himself to physics, mathematics, and geography, becoming one of the most sought-after teachers in Paris for fifteen years. In 1775, he succeeded Giovanni Rizzi-Zannoni as cartographer to the King of France in the Hydrographic Service of the Navy. The Depot of Maps and Plans of the Navy was created by order of King Louis XV in 1720.
