It is rare to find a work of Bonne’s with the maps in early colour. This two volume work was intended to accompany the volumes 92 to 97 of the ‘Encyclopedia Methodical’. The first volume begins with the general work’s ornate engraved frontispiece. The atlas volumes were published separately as offered here. The maps are the work of Rigobert Bonne (1727-95) who was an engineer, mathematician, and cartographer. He succeeded Jacques Nicolas Bellin as the hydrographer at the Depot de la Marine. The atlas is co-published with Nicolas Desmarest (1725-1815), a French physician and geologist. The first 19 maps are of the ancient world. that of North America is entirely blank in the west. It is a wonderful collection of less common maps in lovely colour. The maps are largely engraved by Gaspard Andre with a few noted by ‘Bonne fils’, Rigobert’s son.
