Marie de Rabutin-Chantal, marquise de Sévigné (5 February 1626 – 17 April 1696) was a French aristocrat, remembered for her letter-writing. Most of her letters, celebrated for their wit and vividness, were addressed to her daughter. Her letters provide much insight into the social mores and customs of 17th-century French life.
From the article on French literature in The Columbia Encyclopedia:
The 17th cent. produced the great academies and coteries of French literature. The elegant, controlled aesthetic of French classicism was the hallmark of the age: in the brilliant dramas of Pierre Corneille, Jean Racine, and Molière; in the poetry and satire of Jean de La Fontaine and Nicolas Boileau-Despréaux; in the prose of Blaise Pascal, Marie, marquise de Sévigné, Jacques-Bénigne Bossuet, Marie-Madeleine, comtesse de La Fayette, and François, duc de La Rochefoucauld. The works of the ecclesiastic François de la Mothe Fénelon, the social philosopher Claude Henri, comte de Saint-Simon, and the satirist and classical scholar Jean de La Bruyère belong to this illustrious period as well as to the 18th cent.
These great writers vary enormously in their attitudes and interests but share a style that is lucid, polished, and restrained. They are, as a group, chiefly concerned with observing the subtleties of human behavior. Their works display qualities that have become permanently identified with the best French writing: wit, sophistication, imagination, and delight in debate.
Les parallels with the C21 US political blogosphere are uncanny, non?

Non.
