Gian Francesco Poggio Bracciolini (Italian: [dʒaɱ franˈtʃesko ˈpɔddʒo brattʃoˈliːni]; 11 February 1380 – 30 October 1459), usually referred to simply as Poggio Bracciolini, was an Italian scholar and an early Renaissance humanist. He is noted for rediscovering and recovering many classical Latin manuscripts, mostly decaying and forgotten in German, Swiss, and French monastic libraries. His most celebrated finds are De rerum natura, the only surviving work by Lucretius, De architectura by Vitruvius, lost orations by Cicero such as Pro Sexto Roscio, Quintilian's Institutio Oratoria, Statius' Silvae, Ammianus Marcellinus' Res Gestae (Rerum gestarum Libri XXXI), and Silius Italicus's Punica, as well as works by several minor authors such as Frontinus' De aquaeductu, Nonius Marcellus, Probus, Flavius Caper, and Eutyches.
