On June Twenty-sixth, Seventeen Hundred Fifty, Voltaire applied to the King in person for permission to visit Frederick of Prussia.
Tradition has it that the King replied promptly, "You may go—the sooner the better—and you may remain as long as you choose."
Voltaire pocketed the veiled acerbity without a word, and bowing himself out, made hot haste to pack up and be on his way before an order rescinding the permission was issued.
Frederick was a freethinker, a scientist, a poet, and a wit well worthy of the companionship of Voltaire. In fact, they were very much alike. Both had the dual qualities of being intensely practical and yet iconoclastic. Both were witty, affable, seemingly indifferent and careless, but yet always with an eye on the main chance. Each was small, thin and bony, but both had the intellect of the lean and hungry Cassius that looked quite through the deeds of man.
Frederick received Voltaire with royal honors. Princes, ministers of state, grandees and generals high in office, knelt on one knee as he passed. Frederick tried to make it appear that France had failed to appreciate her greatest philosopher, and so he had come to Prussia—the home of letters. His pension was fixed at twenty thousand francs a year, he was given the Golden Key of Chamberlain, and the Grand Cross of the Order of Merit. He was a member of the King's household, and was the nearest and dearest friend of the royal person.
Frederick thought he had bound the great man to him for life.
Personality repels as well as attracts. Voltaire's viper-like pen was never idle. He wrote little plays for the court, and these were presented with much eclat, the author superintending their presentation, and considerately taking minor parts himself, so as to divide the honors. But amateur theatricals stand for heart-burnings and jealousy. The German poets were scored, other writers ridiculed, and big scientists came in for their share of pen-pricking.
Voltaire corrected the King's manuscript and taught him the secret of literary style. Then they fell into a controversy, done in Caslon old-style, thundering against each other's theories in pamphlets across seas of misundertandings. Neither side publicly avowed the authorship, but nobody was deceived. The King and Voltaire met daily at meals, and carefully avoided the topics they were fighting out in print.
Voltaire was rich and all of his wants were supplied, but he entered the financial lists, and taking advantage of his inside knowledge, speculated in scrip and got into a disgraceful lawsuit over the proceeds with a man he should never have known. Frederick was annoyed—then disturbed. He personally chided Voltaire for his folly in mixing with the King's enemies.
Voltaire had tired of the benevolent assimilation—he craved freedom. A friend who loves you, if he spies upon your every action, will become intolerable. Voltaire intimated to Frederick that he would like to go.
