Voltaire and his niece were allowed to depart. Thus ended the treaty of equal friendship between king and poet. The pettiness of the details is striking. We find neither the magnanimity of a hero in one, nor the calmness of a philosopher in the other. Voltaire had the excuse that he avenged his injured friend Kœnig in his satire on Maupertuis. He had dreamed of independence in a palace; and from the moment he discovered his mistake he was eager to be free. Frederic, meanwhile, was taught by his enemies to regard him as a restless, intriguing Frenchman. He had written to him, at the beginning of their quarrel: "I was glad to receive you. I esteemed your understanding, your talents, your acquirements; and I believed that a man of your age, weary of skirmishing with authors and exposing himself to the storm, would take refuge here as in a tranquil port. First, you exacted from me, in a singular manner, that I should not engage Freron to correspond with me, and I had the weakness to yield. You visited the Russian minister, and talked to him of affairs in which you had no right to interfere; and it was believed that I commissioned you. You had a dirty transaction with a Jew, and filled the city with clamour. I preserved peace in my house till you arrived; and I warn you, that if you have a passion for intrigue and cabal, you have addressed yourself very ill. I like quiet people; and if you can resolve to live like a philosopher, I shall be glad to see you; but if you give way to your passions, and quarrel with everybody, you had better remain at Berlin. * * * * I write this letter with unpolished German good sense, which says what it thinks, and without adopting equivocal terms and soft palliations to disfigure the truth."[6] This letter shows that Frederic believed himself to be in the right, and had conceived a bad opinion of his friend. We all know the height to which misunderstandings can rise when fostered by malicious and interested persons. We cannot wonder that men of quick tempers like Frederic and Voltaire should disagree; but it was to be lamented that they made their pettish quarrels a spectacle for all Europe.
