Voltaire thanks Guazzesi for sending him a book [Guazzesi’s translation of Alzire, published together with Racine’s Iphigenie in 1762], adding that he is too ill to thank him in his own hand, the letter instead being written by his secretary. Voltaire goes on to say that Iphigenie was worthy of being translated by Guazzesi, but that the translator does others [Voltaire] too much honour. He then turns to Guazzesi’s poetry, remarking that his compositions are instructive and agreeable, before speaking of the ancient Romans, noting that they had an unrefined sense of humour. He adds that he can see the mountains that were crossed by Hannibal through his windows.

Voltaire begins by saying that whilst they await the paquet from Berlin, he is sending the recipient a small funny thing with which to treat Frederic II of Prussia, adding that very unfaithful copies of it have been circulated. He instructs Baculard d’Arnaud to give him his thoughts on the trifle, and give him news of his tragedy Catiline. He ends by bidding farewell to Baculard d’Arnaud and noting that he will be in Cirey for all of January. In an addition to the copy of this letter used for the Besterman edition (BNF, MS f.fr. 12941, p.305), Voltaire also notes that he knowns nothing more of the paquet from England and awaits with impatience news of Frederic II, ending his letter with the line: ‘vous serez bien aimable de m’ecrire’.

In this letter, Voltaire responds to a missive from the Marquise Du Deffand and begins by mentioning one of her friends, the captain of dragoons Jean-Baptiste-Nicolas de Lisle (1735-1783) whom Voltaire regrets is convinced that he is the author of an Épître à Ninon. Voltaire praises Russian men and women of letters and claims that French is spoken more purely at the court of Catherine the Great than at Versailles because French ladies do not pride themselves on knowing the grammar. He then turns to Catherine the Great, who he notes does not write verse, but knows her stuff very well, and makes very good jokes about Emilian Pugachev.
