To return to those of M. Zola's masculine characters who may be identified with real personages, none is more genially, more truthfully, portrayed than Chevalier Rusconi, the Italian or, more correctly, Sardinian, Minister in Paris. Here we have that most amiable of men, Chevalier Nigra, of whom Prosper Mérimée once said in my presence: 'C'est un bohème tombé dans la diplomatie.' Withal, Chevalier Nigra--who, though very aged, still serves his country, I believe, with distinction at Vienna--was a very good diplomatist indeed; one of Cavour's right-hand men, one of those to whom Italy owes union and liberty. And what a career was his in France, and what memoirs might he not write! Few diplomatists ever had stranger experiences: from all the secret plotting which so largely helped to make Victor Emmanuel King of Italy to the surveillance so adroitly practised over the Empress Eugénie, whose support of Pope Pius IX. was ever an obstacle to Italian aspirations. For her Nigra-Rusconi became the handsome, gallant courtier; he was a musician, could sing and dance, was proficient in every society accomplishment, and before long the Empress's Monday receptions at the Tuileries, those _petits Lundis_ enlivened by the wit of Mérimée, were never complete without him. Yet, all the time, a stern duel was being fought between him and the consort of Napoleon III. And so long as her husband ruled France she kept her adversary at bay. Rome, capital of Italy, was but the fruit of Sedan. Yet Nigra was chivalrous. When the bitter hour of reckoning arrived, he stood by the woman who had so long thwarted him. He and Prince Richard Metternich smuggled her out of the Tuileries in order that she might escape to England, beyond the reach of the infuriated Parisians.
