10 double-page, and 5 full-page engraved map sheets, together creating a large map of Burgundy (overall size 116 x 99 inches, each sheet with full margins, showing the plate mark). A MAGNIFICENT and very detailed map of Burgundy engraved by Bourgoign le Jeune after Seguin and Cassini, showing the region divided into dioceses, bailiwicks and sub-delegations, all routes, waterways, cities, towns, villages, forests and fields, and all surrounded by a handsome and broad border with large acanthus leaves at each corner and surmounted by a large sun and cloud burst containing the arms of France, with three magnificent, detailed rococo allegorical cartouches containing the legend, the title, and a vignette of the city of Dijon, designed by Galey (some minor browning to one or two sheets).
In 1747 King Louis XV of France (1710-1774), known as Louis the Beloved (Louis le bien aimé), of the House of Bourbon, commissioned César-François Cassini de Thury (Cassini III 1714-1784) to create a complete survey of France, the "Carte de France". This was a huge undertaking, initially funded by the crown, until 1756, subsequently until 1762 by a company of shareholders, and thereafter by the individual provinces of France. Burgundy was one of the first provinces to provide funding for the survey of their region. Of the resulting 180 map sheets of France, 12 created between 1752 and 1762 covered the area of Burgundy, and were used to create this astonishing and first stand-alone regional map of the project. Other regions followed suite, creating a series of maps more decorative and majestic in appearance than those directly published for Cassini's "Carte de France".
Cassini's mammoth map of France was the first complete national map constructed on modern principles of surveying and astronomy. As such, historian Josef Konvitz considers it nothing less than a "monument to the taste and intelligence of the French Enlightenment." The ambitious project, which was jointly managed with Cassini de Thury's son, Jacques-Dominique, ultimately took nearly seven decades to complete and required the efforts of more than eighty individuals. "By 1760, 50 maps of the 180 projected were finished, all in the north-central part of France. Between 1760 and 1770, 38 were published, covering all of eastern France, central France north of Lyon, and western France east of Rennes and north of Poitiers. Forty-five more were available by 1780, covering Anjou, Poitou, the Dauphin, and Provence. The Limousin, the Pyrenees frontier, and the region of Nice appeared between 1780 and 1789. All fieldwork but not all engraving was completed by 1789." (Konvitz, Cartography in France 1660-1848. Chicago, 1987, pp. 21-25).
Cassini de Thurry and Jean-Dominique's project was largely completed by the beginning of the French Revolution. Though their venture had been initially funded by the French government, Cassini de Thury had later decided to finance the project through the selling of shares to nobles, officials, and other leading members of society like Louis XV's mistress, Madame de Pompadour. In 1793 the revolutionary government expropriated the Cassini's maps, as they were of great military value. The Revolutionary government at that time also proceeded to dissolve Cassini de Thury's company and to execute its former president and treasurer. Though Napoleon ensured that all of the Cassini's shareholders be paid for their losses following the conclusion of the French Revolution, Cassini de Thury's son, Jacques-Dominique, never regained control of his family's project. Nevertheless, the Cassinis had still succeeded in producing the first complete geometric map, and had, thus, ushered in the modern era of mapmaking.
