A substantial portion of Cicero's lost De re publica emerged into modern scholarship through the systematic chemical treatment of erased parchment manuscripts by Angelo Mai. Working in Milan and Rome, this Italian philologist recovered significant ancient texts that had been washed away to make space for later writings, effectively salvaging classical literature from centuries of oblivion.
Early Formation and Academic Training
Born in 1782 at Schilpario in Lombardy, Mai entered the Society of Jesus in 1799. He refined his linguistic and palaeographical abilities while studying at the Pontifical Gregorian University and the Collegium Romanum. After a period of teaching in Naples and Orvieto, political instability caused by French military operations in 1808 forced his departure from Rome. He eventually settled in Milan, where his career as a custodian of ancient texts began in earnest.

Appointed custodian of the Ambrosian Library in 1813, Mai utilized chemical reagents to reveal underlying layers of palimpsests. His successes there included publishing fragments of Cicero's speeches and works by Fronto and Symmachus. Upon his move to Rome in 1819 to serve as chief keeper of the Vatican Library, he expanded his efforts, compiling the massive Scriptorum veterum nova collectio and the Classici scriptores e Vaticanis codicibus editi, which spanned several decades of intensive archival research.
Ecclesiastical Career and Final Years
Mai transitioned from library science to broader administrative duties within the Catholic Church, becoming secretary of the Congregation of the Propaganda in 1833. His stature within the Vatican grew, culminating in his elevation to cardinal on 12 February 1838. He continued his editorial output until his death on 8 September 1854 at Albano Laziale. His remains were interred in the Basilica di Sant'Anastasia al Palatino, inside a monument sculpted by Giovanni Maria Benzoni.
