He founded a rich library at the Palazzo Barberini which included ancient Greek and Roman manuscripts, and he supported numerous European intellectuals, scholars, scientists and artists, including Athanasius Kircher, Jean Morin, Gabriel Naudé, Gerhard Johann Vossius, Heinsius and John Milton. Also at the Palazzo Barberini, he initiated a small natural science museum and botanical garden and his collections attested to his interests in ancient sculpture, numismatics and inscriptions. The " Libellus de Medicinalibus Indorum Herbis", sometimes referred to as the "Codex Barberini", was named in his honour.
