Fine example of Alexandre Ruelle's rare world map on Cassini's projection, showing the resutls of his astronomical observations.
Alexandre Ruelle and J. Perny de Villeneuve were retained by Jean Dominique Comte de Cassini to make daily and nightly celestial observations at the Paris Observatory and prepare the data for annual publication. He was later imprisoned for making up some of his observational data and would ultimately become a bitter enemy of Cassini. Ruelle woud later publish a manual of the constellations. The map shows the route of Bouganinville around the world.

Jean-Claude Dezauche (fl. 1780-1838) was a French map publisher. He edited and reissued the maps of Guilluame De L’Isle and Philippe Buache, two of the most skilled mapmakers of the eighteenth century. He acquired the plates of these two men’s work in 1780 from Buache’s heir, Jean Nicholas Buache. Dezauche worked in the Depot de la Marine, as had the elder Buache.
