Fine old color example of Pierre Mortier's large map of the Orleans region, published in Amsterdam.
The map is centered on the course of the Loire River, between tracking though La Charite, Pouilly, Sancerre, Cosne, Beaulieu, Bonny, Chastillon, Briare, Sully, Orleans, Meun, Baugency, Menars, Suever, Blois, Onzaine, Amboise and Tours.
The map credits Sanson as the mapmaker, but in fact it is drawn directly from the map of Alex-Hubert Jaillot.
Pierre, or Pieter, Mortier (1661-1711) was a Dutch engraver, son of a French refugee. He was born in Leiden. In 1690 he was granted a privilege to publish French maps in Dutch lands. In 1693 he released the first and accompanying volume of the Neptune Francois. The third followed in 1700. His son, Cornelis (1699-1783), would partner with Johannes Covens I, creating one of the most important map publishing companies of the eighteenth century.
