"It is Cæsar, it is Marcus Aurelius, it is Julian, it is sometimes Abbé Chaulieu, with whom I sup," he further wrote; "there is the charm of retirement, there is the freedom of the country, with all those little delights which the lord of a castle who is a king can procure for his very obedient humble servants and guests. My own duties are to do nothing. I enjoy my leisure. I give an hour a day to the King of Prussia to touch up a bit his works in prose and verse; I am his grammarian, not his chamberlain ... Never in any place in the world was there more freedom of speech touching the superstitions of men, and never were they treated with more banter and contempt. God is respected, but all they who have cajoled men in His name are treated unsparingly."

It was, in short, an Eden for a free-thinker; but an Eden with its serpent, and this serpent was the envy, jealousy, and unrestrainable satiric spirit of Voltaire. There was soon trouble between him and his fellow-exiles. He managed to get Arnaud exiled from the country, and gradually a coolness arose between him and Maupertuis, whom Frederick had made president of the Berlin Academy. There were other quarrels and complications, and Voltaire grew disgusted with the occupation of what he slyly called "buck-washing" the king's French verses,—poor affairs they were. Step by step he was making Berlin as hot as he had made Paris. The new Adam was growing restless in his new Paradise. He wrote to his niece,—

"So it is known by this time in Paris, my dear child, that we have played the 'Mort de Cæsar' at Potsdam, that Prince Henry is a good actor, has no accent, and is very amiable, and that this is the place for pleasure? All this is true, but—The king's supper parties are delightful; at them people talk reason, wit, science; freedom prevails thereat; he is the soul of it all; no ill-temper, no clouds, at any rate no storms; my life is free and well occupied,—but—Opera, plays, carousals, suppers at Sans Souci, military manœuvres, concerts, studies, readings,—but—The city of Berlin, grand, better laid out than Paris; palaces, play-houses, affable queens, charming princesses, maids of honor beautiful and well-made, the mansion of Madame de Tyrconnel always full and sometimes too much so,—but—but—My dear child, the weather is beginning to settle down into a fine frost."

Voltaire brought the frost. He got into a disreputable quarrel with a Jew, and meddled in other affairs, until something very like a quarrel arose between him and Frederick. The king wrote him a severe letter of reprimand. The poet apologized. But immediately afterwards his irrepressible spirit of mischief broke out in a new place. It was his ill-humor with Maupertuis which now led him astray. He wrote a pamphlet, full of wit and as full of bitterness, called "La diatribe du docteur Akakia," so evidently satirizing Maupertuis that the king grew furious. It was printed anonymously, and circulated surreptitiously in Berlin, but a copy soon fell into Frederick's hand, who knew at once that but one man in the kingdom was capable of such a production. He wrote so severely to Voltaire that the malicious satirist was frightened and gave up the whole edition of the pamphlet, which was burnt before his eyes in the king's own closet, though Frederick could not help laughing at its wit.

But Voltaire's daring was equal to a greater defiance than Frederick imagined. Despite the work of the flames, a copy of the diatribe found its way to Paris, was printed there, and copies of it made their way back to Prussia by mail. Everybody was reading it, everybody laughing, people fought for copies of the satire, which spread over Europe. The king, enraged by this treacherous disobedience, as he deemed it, retorted on Voltaire by having the pamphlet burned in the Place d'Armes.

This brought matters to a crisis. The next day Voltaire sent his commissions and orders back to Frederick; the next, Frederick returned them to him. He was bent on leaving Prussia at once, but wished to do it without a quarrel with the king.

"I sent the Solomon of the North," he wrote to Madame Denis, "for his present, the cap and bells he gave me, with which you reproached me so much. I wrote him a very respectful letter, for I asked him for leave to go. What do you think he did? He sent me his great factotum, Federshoff, who brought me back my toys; he wrote me a letter saying that he would rather have me to live with than Maupertuis. What is quite certain is that I would rather not live with either the one or the other."

In truth, Frederick could not bear to lose Voltaire. Vexed as he was with him, he was averse to giving up that charming conversation from which he had derived so much enjoyment. Voltaire wanted to get away; Frederick pressed him to stay. There was protestation, warmth, coolness, a gradual breaking of links, letters from France urging the poet to return, communications from Frederick wishing him to remain, and a growing attraction from Paris drawing its flown son back to that centre of the universe for a true Frenchman.

At length Frederick yielded; Voltaire might go. The poet approached him while reviewing his troops.

"Ah! Monsieur Voltaire," said the king, "so you really intend to go away?"
