"A thorough knowledge of all languages, ancient and modern; a prodigious memory; erudition, of which glimpses could be caught between the caprices of his conversation, which was always amusing and occasionally very engaging; an inexhaustible skill in varying the tone and subjects of his converse; in being always fresh and in infusing the unexpected into the most ttivial discourses made him a superb talker. Sometimes he recounted anecdotes of the court of the Valois or of princes still more remote, with such precise accuracy in every detail as almost to create the illusion that he had been an eyewitness to what he narrated. He had traveled the whole world over and the king lent a willing ear to the narratives of his voyages over Asia and Africa, and to his tales about the courts of Russia, Turkey and Austria. He appeared to be more imtimately acquainted with the secrets of each court than the charge d'affaires of the king."
