His first impressions of Rome were not favourable, and his first letter was even querulous; but soon his clear single mind grew strong again; and the spirit of his correspondence during the whole seven years of his Roman residence is delightful. Children brought out the fatherly part of his character; his wife was ever his loving and devoted companion; some powerful and interesting minds sought his companionship; and a taste for art was improved by intercourse with the rising young artists who were then at Rome--Cornelius, Overbeck, Schadow; but, above all, the education of Marcus, his eldest child and only boy, who can wonder if he became more and more of a Roman, and if he closed the seventh year of his residence mournfully when preparing for his return to Germany? His mission had been a difficult one--not that the papal court was unfriendly, but the home instructions were not always clear and consistent. An earnest Protestant himself, he was yet profoundly alive to the duties of rulers towards all their subjects, of all religious beliefs, and wished in every negotiation to make sure of a large measure of real freedom. When at length the concordatives were agreed to, he was anxious for a recall, on account, chiefly, of the delicate state of Mme Niebuhr's health; but for this he had some little time to wait. It is interesting to see the manner in which he was affected by the passing events of this time. 'Idle talk,' says M. Bunsen, 'on matters of lofty import, and a dwelling with pleasure upon trifling topics, were equally abhorrent to him. I shall never forget how Niebuhr spoke at a princely table in Rome, during the bloody scenes in Greece, of Suli and the Suliots, and the future of the Christian Hellenes, in much the same terms as he has spoken to posterity in a passage of his Roman history, which breathes a noble indignation, and a sense that the brand of infamy still cleaves to us. The prince, a high-minded, amiable, and intelligent man, listened, as did his guests, with attention and sympathy; a serious mood seemed to come over the whole party; a pause occurred. One of the guests, a diplomatist, of Mephistophelian aspect and species, took advantage of it to turn the conversation. One of the eternally repeated trifles of the day--a so-called piece of news that must be repeated to the prince--was skilfully used as a stepping-stone; and in ten minutes, the whole table was alive with a dispute between the spokesman and another person who had contradicted him on a most important point--what "aurora" signified in the slang of the Roman coffeehouses, whether a mixture of chocolate with coffee or not. Niebuhr was silent. At last, with quiet earnestness and dignified mien, he spoke these words: "What heavy chastisements must be still in store for us, when, in such times, and with such events still occurring around us, we can be entertained with such miserable trifles!" All were mute, and Niebuhr also. A long pause ensued; and
