Voltaire's Terrestrial Paradise at Berlin did not long continue perfect. Scarcely had that grand Carrousel vanished in the azure firmaments, when little clouds began rising in its stead; and before long, black thunder-storms of a very strange and even dangerous character. It must have been a painful surprise to Friedrich to hear from his Voltaire, some few weeks after those munificences, That he, Voltaire, was in very considerable distress of mind, from the bad, not to call it the felonious and traitorous, conduct of M. D'Arnaud,--once Friedrich's shoeing-horn and "rising-sun" for Voltaire's behoof; now a vague flaunting creature, without significance to Friedrich or anybody! That D'Arnaud had done this and done that, of an Anti-Voltairian, treasonous nature;--and that, in short, life was impossible in the neighborhood of such a D'Arnaud!"D'Arnaud has corrupted my Clerk (Prince Henri hungering in vain for LA PUCELLE, has got sight of it, in this way); [Clerk was dismissed accordingly (one Tinois, an ingenious creature),--and COLLINI appointed in his stead.] D'Arnaud has been gossiping to Freron and the Paris Newspapers; D'Arnaud has" [Voltaire to Friedrich (--OEuvres de Frederic,--xxii. 257), undated, "November, 1750."]--Has, in effect, been a flaunting young fool; of dissolute, esurient, slightly profligate turn; occasionally helping in the Theatricals, and much studious to make himself notable, and useful to the Princely kind. A D'Arnaud of nearly no significance, to Friedrich or to anybody. A D'Arnaud whose bits of fooleries and struttings about, in the peacock or jackdaw way, might surely have been below the notice of a Trismegistus! Friedrich, painfully made sensible what a skinless explosive Trismegistus he has got on hand, answers, I suppose, in words little or nothing,--in Letters, I observe, answers absolutely nothing, to Voltaire repeating and re-repeating;--does simply dismiss D'Arnaud (a "BON DIABLE," as Voltaire, to impartial people, calls him), or accept D'Arnaud's demission, and cut the poor fool adrift. Who sallies out into infinite space, to Paris latterly ("alive there in 1805"); and claims henceforth perpetual oblivion from us and mankind. And now there will be peace in our garden of the gods, and perpetual azure will return?
