Matteo di Marco Palmieri (1406–1475) was a Florentine humanist and historian who is best known for his work Della vita civile ("On Civic Life"; printed 1528) which advocated civic humanism, and his influence in refining the Tuscan vernacular to the same level as Latin.[1] He was sent as Florentine ambassador to the court of Alfonso I of Naples. Vespasiano da Bisticci included him among the illustrious men of his generation whose careers deserved an article in his Vite di uomini illustri del secolo XV[2] vita.
