Gian Francesco Poggio Bracciolini, usually referred to simply as Poggio Bracciolini, was an Italian scholar and an early Renaissance humanist. He was responsible 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, and Silius Italicus's Punica, as well as works by several minor authors such as Frontinus' De aquaeductu, Ammianus Marcellinus’ Res Gestae, Nonius Marcellus, Probus, Flavius Caper, and Eutyches.
