An historical essay concerning the failed conspiracy by Gian Luigi Fieschi against the doge Andrea Doria in 1547, the object of which was to make Genoa a French protectorate. Written when the author, de Gondi, was only 18 but anonymously published much later. The city "Cologne" and the sphere on the title page indicate it was published by Elzevier, the Dutch publishing house in Amsterdam, though they did not wish to attach their name to it. French text.
