Frederick, who was then in the zenith of his admiration for Voltaire, describes as follows, in a letter to his friend M. Jordan, his impressions of the interview:

“I have at length seen Voltaire, whom I was so anxious to know. But, alas! I saw him when under the influence of my fever, and when my mind and my body were equally languid. With persons like him one ought not to be sick. On the contrary, one ought to be specially well. He has the eloquence of Cicero, the mildness of Pliny, and the wisdom of Agrippa. He unites, in a word, all the collected virtues and talents of the three greatest men of antiquity. His intellect is always at work. Every drop of ink that falls from his pen is transformed at once into wit. He declaimed his _Mahomet_ to us, an admirable tragedy which he has composed. I could only admire in silence.”

Indeed, it would seem that, at the time, Voltaire must have been very favorably impressed by the appearance of his royal host. The account he then gave of the interview was very different from that which, in his exasperation, he wrote twenty years afterward. In a letter to a friend, M. De Cideville, dated October 18th, 1740, Voltaire wrote:

“When you sent me, inclosed in your letter, those verses for our Marcus Aurelius of the North, I fully intended to pay my court to him with them. He was at that time to have come to Brussels _incognito_. But the quartan fever, which unhappily he still has, deranged all his projects. He has sent me a courier to Brussels, and so I set out to find him in the neighborhood of Cleves.

“It was there that I saw one of the most amiable men in the world, who forms the charm of society, who would be every where sought after if he were not a king; a philosopher without austerity, full of sweetness, complaisance, and obliging ways--not remembering that he is king when he meets his friends; indeed, so completely forgetting it that he made me too almost forget it, and I needed an effort of memory to recollect that I here saw, sitting at the foot of my bed, a sovereign who had an army of a hundred thousand men.”
