First edition of the French translation by Jean-Baptiste Dupuy-Demportes of the work originally published in 1689 under the title "La Morale dei principi osservata nell'istoria di tutti gl'imperadori, che regnarono in Roma" (cf. Quérard II, 260. Barbier III, 353b. Conlon VII, 54-572. Hoefer XI, 314).
Contemporary full red morocco bindings, spines with five raised bands decorated with gilt fillets and double gilt panels with gilt floral tools, boards framed by gilt roll-tooled floral and bird motifs, gilt fillets on the board edges, marbled endpapers and pastedowns, all edges gilt over marbling.
Some gatherings bound out of sequence in volumes 1 and 3; headcap of volume 4 chipped; a few small wormholes, mostly affecting the lower sections of the bindings.
A handsome copy of this uncommon work.
Giovanni Battista Comazzi (Mantua, 1654 – Vienna, 1711), an Italian historian, poet, and political theorist, presents here a study of Roman emperors from Caesar to Constantius Chlorus: "Il prend les traits principaux de la vie de chaque prince, il en cherche les vues et les causes, et juge, d'après les principes, s'ils ont eu tort ou raison, et pourquoi ; ainsi chaque fait historique donne occasion à une maxime morale" (Nouvelles littéraires, 20 juillet 1754).
