(PAS DE CALAIS-62) Louis DENIS (1725–1794) – “Map of the Road from Arras to St. Omer and Calais...” - 18th century. Engraving enhanced with watercolor on laid paper by Louis Denis in 1776, published in his famous collection of maps titled *Le Conducteur français*. Engraved by Chalmandrier. The map begins in Arras, heads northwest through the hills of Artois via Souchez, enters the Audomarois marshes, and ends in Saint-Omer. The old route is so deeply ingrained there that the city’s current southern entrance still bears the historic name Rue d’Arras; it continues across the coastal plain through Ardres, ending behind the imposing ramparts of the port of Calais. (200 x 535 mm) - Condition A-. Map with notches. Printing creases. A few foxing spots.
