Palmieri firmly believed in the humanist ideal that "virtù" was a combination of both learning and political action, and so in concordance with his political life, he was also an author. He wrote in both Latin and Italian. Among his Latin works are "Liber de temporibus" (Book of Epochs), a universal chronicle of the world from the time of creation to his present day; the "De captivitate liber" (The Capture of Pisa), an account of the Florentine capture of Pisa in 1406; and a biography of Niccolò Acciaioli, translated into Italian by Donato Acciaioli.
