An explosion of this kind, it might be supposed, would necessarily put an end to all amicable communication. But it was not so. After every outbreak of ill humor this extraordinary pair became more loving than before, and exchanged compliments and assurances of mutual regard with a wonderful air of sincerity.
It may well be supposed that men who wrote thus to each other were not very guarded in what they said of each other. The English ambassador, Mitchell, who knew that the King of Prussia was constantly writing to Voltaire with the greatest freedom on the most important subjects, was amazed to hear his Majesty designate this highly favored correspondent as a bad-hearted fellow, the greatest rascal on the face of the earth. And the language which the poet held about the King was not much more respectful.
It would probably have puzzled Voltaire himself to say what was his real feeling towards Frederic. It was compounded of all sentiments, from enmity to friendship, and from scorn to admiration; and the proportions in which these elements were mixed changed every moment. The old patriarch resembled the spoiled child who screams, stamps, cuffs, laughs, kisses, and cuddles within one quarter of an hour. His resentment was not extinguished; yet he was not without sympathy for his old friend. As a Frenchman, he wished success to the arms, of his country. As a philosopher, he was anxious for the stability of a throne on which a philosopher sat. He longed both to save and to humble Frederic. There was one way, and only one, in which all his conflicting feelings could at once be gratified. If Frederic were preserved by the interference of France, if it were known that for that interference he was indebted to the mediation of Voltaire, this would indeed be delicious revenge; this would indeed be to heap coals of fire on that haughty head. Nor did the vain and restless poet think it impossible that he might, from his hermitage near the Alps, dictate peace to Europe. D'Estrées had quitted Hanover, and the command of the French army had been entrusted to the Duke of Richelieu, a man whose chief distinction was derived from his success in gallantry. Richelieu was in truth the most eminent of that race of seducers by profession, who furnished Crébillon the younger and La Clos with models for their heroes. In his earlier days the royal house itself had not been secure from his presumptuous love. He was believed to have carried his conquests into the family of Orleans; and some suspected that he was not unconcerned in the mysterious remorse which embittered the last hours of the charming mother of Louis the Fifteenth. But the Duke was now sixty years old. With a heart deeply corrupted by vice, a head long accustomed to think only on trifles, an impaired constitution, an impaired fortune, and, worst of all, a very red nose, he was entering on a dull, frivolous, and unrespected old age. Without one qualification for military command, except that personal courage which was common between him and the whole nobility of France, he had been placed at the head of the army of Hanover; and in that situation he did his best to repair, by extortion and corruption, the injury which he had done to his property by a life of dissolute profusion.
