"Madame had tried the pure sciences and philosophies, in Books: but how much more charming, when they come to you as a Human Philosopher; handsome, magnanimous, and the wittiest man in the world! Young Madame was not regularly beautiful; but she was very piquant, radiant, adventurous; understood other things than the pure sciences, and could be abundantly coquettish and engaging. I have known her scuttle off, on an evening, with a couple of adventurous young wives of Quality, to the remote lodging of the witty M. de Voltaire, and make his dim evening radiant to him. [One of Voltaire's Letters.] Then again, in public crowds, I have seen them; obliged to dismount to the peril of Madame's diamonds, there being a jam of carriages, and no getting forward for half the day. In short, they are becoming more and more intimate, to the extremest degree; and, scorning the world, thank Heaven that they are mutually indispensable. Cannot we get away from this scurvy wasp's-nest of a Paris, thought they, and live to ourselves and our books? "Madame was of high quality, one of the Breteuils; but was poor in comparison, and her Husband the like. An old Chateau of theirs, named Cirey, stands in a pleasant enough little valley in Champagne; but so dilapidated, gaunt and vacant, nobody can live in it. Voltaire, who is by this time a man of ample moneys, furnishes the requisite cash; Madame and he, in sweet symphony, concert the plans: Cirey is repaired, at least parts of it are, into a boudoir of the gods, regardless of expense; nothing ever seen so tasteful, so magnificent; and the two withdraw thither to study, in peace, what sciences, pure and other, they have a mind to. They are recognized as lovers, by the Parisian public, with little audible censure from anybody there,--with none at all from the easy Husband; who occasionally even visits Cirey, if he be passing that way; and is content to take matters as he finds them, without looking below the surface. [See (whosoever is curious) Madame de Grafigny, _Vie Privee de Voltaire et de Madame du Chatelet_ (Paris, 1820). A six months of actual Letters written by poor Grafigny, while sheltering at Cirey, Winter and Spring, 1738-1739; straitened there in various respects,--extremely ill off for fuel, among other things. Rugged practical Letters, shadowing out to us, unconsciously oftenest, and like a very mirror, the splendid and the sordid, the seamy side and the smooth, of Life at Cirey, in her experience of it. Published, fourscore years after, under the above title.] For the Ten Commandments are at a singular pass in cultivated France at this epoch. Such illicit-idyllic form of life has been the form of Voltaire's since 1733,"--for some three years now, when Friedrich and we first make acquaintance with him. "It lasted above a dozen years more: an illicit marriage after its sort, and subject only to the liabilities of such. Perhaps we may look in upon the Cirey Household, ourselves, at some
