and the very prolific R Bonne took over the Dépôt. Rizzi soon
moved back to his native Italy.
Most of his works

1762, "Atlas Historique de la France" and "Le Petit Neptune

1787 edition of the 1776 Jean Lattre's "Atlas Moderne", to

Late editions of said atlas are known to incorporate significant
new maps of the North American continent, specially for the
US, Mexico and the Gulf.
delineation of the coast lines dates a little; the Florida
archipelago representation in particular had already been
abandoned by cartographers such as Bonne as early as in 1780.
But otherwise, it is characterized by the minutia that Rizzi-Zannoni
always brought to his works.
Notice that longitudes are given west of the meridian of Paris,
as it was then customary in France.
