These three letters are all addressed to "My dear angel" or "My divine angels". In the letters, Voltaire talks of his ailing health. In the letter of April 25, 1764, he mentions his dealings with foreign contacts from Italy and Spain. In the two letters from 1769, he talks of his ailing health and hopes that Madame D'Argental is in good health. In both letters from 1769 he discusses religious matters, mentions the pope and some mythological figures such as Pluto and Venus. In the letter of August 30, 1769, Voltaire says that he cannot meddle in the case of Martin because he already has his hands full with the case of Pierre-Paul Sirven, who was unjustly persecuted because he was protestant. Voltaire says that he dreams of Sirven, Martin, Jean Calas, and others. The letter of 1764 and the letter of August 30, 1769 are both signed with a "V."
