An engrossing group of maps from this scarce atlas that is exceptional for its thematic maps and "spheroidal" maps of the world, which have a three-dimensional effect. The popularity of thematic maps reached its zenith in the mid-nineteenth century when advances in printing techniques made possible the production of maps that could clearly display the spatial aspects of physical and cultural phenomena. Sizes vary slightly on sheet size 34 x 24". Printed color with some finishing by hand. Included in this lot are:

No. 2. Tableau d' Uranographie Moderne ou Systeme Spheroidal Celeste is a description of the solar system, showing the constellations in the skies of autumn, winter, spring and summer. At the bottom is a series of three spheres showing the North and South Poles, and the Copernican solar system.
No. 3. Tableau des Principales Projections Usitees pour la Construction des Cartes Geographiques. This shows the various global projections used by mapmakers, including Mercator, Flamsteed, and many more.
No. 5. Tableau Comparatif de l'Etat des Connaissances Geographiques. This map shows the voyages of discovery with a chart at bottom with the dates and explorations.
