"Sir, urgent private affairs, and especially my health, leave me no alternative." "Monsieur, I wish you a pleasant journey." This was enough for Voltaire; in an hour he was in his carriage and on the road to Leipsic. He thought he was done for the rest of his life with the "exactions" and "tyrannies" of the King of Prussia. He was to experience some more of them before he left the land. Frederick bided his time. It was on March 26, 1753, that Voltaire left Potsdam. It was two months afterwards before he reached Frankfort. He had tarried at Leipsic and at Gotha, engaged in the latter place on a dry chronicle asked for by the duchess, entitled "The Annals of the Empire." During this time also, in direct disregard of a promise he had made Frederick, there appeared a supplement to "Doctor Akakia," more offensive than the main text. It was followed by a virulent correspondence with Maupertuis. Voltaire was filling up the vials of wrath of the king. On May 31 he reached Frankfort. Here the blow fell. There occurred an incident which has become famous in literary history, and which, while it had some warrant on Frederick's side, tells very poorly for that patron of literature. No unlettered autocrat could have acted with less regard to the rights and proprieties of citizenship. "Here is how this fine adventure came about," writes Voltaire. "There was at Frankfort one Freytag, who had been banished from Dresden and had become an agent for the King of Prussia....He notified me, on behalf of his Majesty, that I was not to leave Frankfort till I had restored the valuable effects I was carrying away from his Majesty. "'Alack, sir, I am carrying away nothing from that country, if you please, not even the smallest regret. What, pray, are those jewels of the Brandenburg crown that you require?' "'It be, sir,' replied Freytag, 'the work of _poeshy_ of the king, my gracious master.' "'Oh, I will give him back his prose and verse with all my heart,' replied I, 'though, after all, I have more than one right to the work. He made me a present of a beautiful copy printed at his expense. Unfortunately, the copy is at Leipsic with my other luggage.' "Then Freytag proposed to me to remain at Frankfort until the treasure which was at Leipsic should have arrived; and he signed an order for it." The volume which Frederick wanted he had doubtless good reason to demand, when it is considered that it was in the hands of a man who could be as malicious as Voltaire. It contained a burlesque and licentious poem, called the "Palladium," in which the king scoffed at everybody and everything in a manner he preferred not to make public. Voltaire in Berlin might be trusted to remain discreet. In Paris his discretion could not be counted on. Frederick wanted the poem in his own hands.
