Those are traits worth remembering in the history of human nature. Who could have conceived the most daring of warriors, the most subtle of politicians, and the most ambitious of kings, in the writer of letters such as these?-- "My house, indeed, is not a place for those who are fond of noisy pleasures; but are not tranquillity, quiet, and the search for truth, to be preferred to the giddy and turbulent diversions of this world? "On the 25th I am going to Amaltheu, my beloved garden at Ruppin. I am quite impatient to see again my vines, my cherries, and my melons; there, free from all useless cares, I shall live entirely for myself. My whole soul is now intent on philosophy. It renders me incomparable services, and I am deeply indebted to it. My spirit is less agitated by impetuous emotions. I repress the first working of my passions, and I never make a choice until I have maturely considered it." All his letters are in the same strain of studious quiet, of steady self-control, and of systematic love of retirement. He sometimes even turns enthusiast, and he thus writes to Voltaire, _then_ known chiefly as the author of the _Henriade_--(his worse celebrity, as the impugner of all religion, was still at a distance.) In a letter, in 1738, he addresses the Frenchman in this rapturous effusion:-- "At Rheinsberg, to be perfectly happy, we want only a Voltaire. But, though you live far from us, still you are in our midst. Your portrait adorns my library; it hangs over the bookcase which contains our Golden Fleece, immediately above your works, and opposite to the place where I generally sit, that I may always have it in my view. I might almost say, that your picture is to me as the statue of Memnon, which, when the sun's rays fell on it, emitted harmonious sounds, and imparted inspiration to the mind of every one who looked upon it." In another letter he writes-- "In pagan antiquity, men offered to the gods the first fruits of the harvest and of the vintage.... In the Romish church, they devote not only the firstborn, not only the younger sons, but whole kingdoms, as we see in the instance of St Louis, who renounced his in favour of the Virgin Mary. For my part, I have no first fruits of the earth, no children, and no kingdom to devote; but I devote to you the first fruits of my muse in the year 1739. Were I a pagan, I would address you by the name of Apollo; were I a Papist, I might have chosen you for my patron saint, or my confessor; but, being none of these, I am content to admire you as a philosopher, to love you as a poet, and to esteem you as a friend." But this romance was soon to be exchanged for reality; the elegancies of royal idleness were to be forgotten in the sound of cannon, and the fictions of a pampered fancy were to be thrown into the shade by the vicissitudes of one of the most sanguinary struggles that Europe had ever seen.
