"

Renaissance humanists such as Poggio Bracciolini sought out in Europe's monastic libraries the Latin literary, historical, and oratorical texts of antiquity, while the fall of Constantinople (1453) generated a wave of émigré Greek scholars bringing precious manuscripts in ancient Greek, many of which had fallen into obscurity in the West. It was in their new focus on literary and historical texts that Renaissance scholars differed so markedly from the medieval scholars of the Renaissance of the 12th century, who had focused on studying Greek and Arabic works of natural sciences, philosophy, and mathematics, rather than on such cultural texts.[citation needed]
