Of the military sort, about this time, Keith and Rothenburg appear most frequently as guests or companions. Rothenburg had a great deal of Friedrich's regard: Winterfeld is more a practical Counseller, and does not shine in learned circles, as Rothenburg may. A fiery soldier too, this Rothenburg, withal;--a man probably of many talents and qualities, though of distinctly decipherable there is next to no record of him or them. He had a Parisian Wife; who is sometimes on the point of coming with Niece Denis to Berlin, and of setting up their two French households there; but never did it, either of them, to make an Uncle or a Husband happy. Rothenburg was bred a Catholic: "he headed the subscription for the famous 'KATHOLISCHE KIRCHE,'" so delightful to the Pope and liberal Christians in those years; "but never gave a sixpence of money," says Voltaire once: Catholic KIRK was got completed with difficulty; stands there yet, like a large washbowl set, bottom uppermost, on the top of a narrowish tub; but none of Rothenburg's money is in it. In Voltaire's Correspondence there is frequent mention of him; not with any love, but with a certain secret respect, rather inclined to be disrespectful, if it durst or could: the eloquent vocal individual not quite at ease beside the more silent thinking and acting one. What we know is, Friedrich greatly loved the man. There is some straggle of CORRESPONDENCE between Friedrich and him left; but it is worth nothing; gives no testimony of that, or of anything else noticeable:--and that is the one fact now almost alone significant of Rothenburg. Much loved and esteemed by the King; employed diplomatically, now and then; perhaps talked with on such subjects, which was the highest distinction. Poor man, he is in very bad health in these months; has never rightly recovered of his wounds; and dies in the last days of 1751,--to the bitter sorrow of the King, as is still on record. A highly respectable dim figure, far more important in Friedrich's History than he looks. As King's guest, he can in these months play no part.
