Antonio Zatta; 1757- 1797.

A venetian publisher, Zatta specialized in italian versions of successful books and atlases.
Of note: the 1775 "Atlante novissimo, illustrato ed accresciuto sulle osservazioni e scoperte fatte dai piu celebri e piu recenti cartografi" in 4 volumes containing 218 finely detailed maps.
It was re-edited till 1785.
Also the 1778 "Storia dell' America settentrionale.." a translation of a Raynal's work. It included twelve maps for the USA, strongly inspired from John Mitchell's seminal 1755 "Map of the british and french dominions in North America". But in a rare precursory manner he renamed the group of maps "Colonie unite dell America Settentrionale", or "The United Colonies of north America". Starting in 1779, these twelve maps were incorporated in the 'Atlante novissimo ..". Others maps were directly translated from the publications of Guillaume Thomas François Raynal - Rigobert Bonne/Giovanni Rizzi-Zannoni).
Also of note: the 1799 posthumous "Nuovo Atlante" issued by his son.

Il Paese de' selvaggi Outauacesi, e Kilistinesi intorno al lago Superiore. .

This large scale map (16 5/8" X 12 1/8") was designed to be the top left corner of the twelve composite maps forming the "Colonie Unite".
Its title, above the top neat line, translates into "The country of the savage Ottawas and Christinaux on the shore of lake Superior".
At the second treaty of Paris in 1783 consecrating the birth of the United States, the John Mitchell map was used to define the border between the territories of the independent colonies and Canada.
The treaty text stipulates in particular that the border line will pass ".through Lake Superior northward of the Isles Royal and Phelipeaux to the long Lake.". Which is still today the official definition of this frontier line.the problem being that the island Philippeaux never existed! With the exception of Isle Royale, the other islands were fictitious and were the creation of Pierre Francois Charlevoix (1682-1761) a French Jesuit priest who explored Canada and America's northeastern regions between 1705-1720. Charlevoix created the islands to honor his patron Jean Frederic Phelippeaux, Comte de Maurepas whose family estate was named Ponchartrain and whose Patron Saint was St. Anne.
The fictitious islands of Phillipeaux, St. Anne, Maurepas and Ponchartrain appeared on many maps until later explorers were able to discount their existence in the early 19th century.
The inset shows the southern tip of Florida: a clear demonstration of the ignorance of the british when it came to this piece of land.
