Daniel de la Feuille was a watchmaker, goldsmith, engraver, and bookseller in Amsterdam in the late 17th and early 18th centuries. He was also a prolific mapmaker. In this “portable atlas,” de la Feuille documented the intricacies of the War of Spanish Succession (1701-14), which began after the Habsburg king of Spain, Charles II, died and left his kingdom to Philip, the Duke of Anjou and the grandson of the French Bourbon king, Louis XIV. Worried that France’s Sun King intended to dominate Europe by consolidating his power in a Bourbon Franco-Spanish state, a competing alliance of European powers, led by Great Britain, launched a preventive war to challenge the prospect of French hegemony. This map presents a survey of the military architecture of the day, including fortifications, frigates and sailing vessels, weaponry, and war matériel used in the new European theater of war.
