Bernard Silvestris

Bernardus Silvestris, also known as Bernard Silvestris and Bernard Silvester, was a medieval Platonist philosopher and poet of the 12th century. Little is known about Bernardus's life, but scholarly consensus suggests he was distinct from Bernard of Chartres. His work, consistent with the Chartres school, is often referred to as 'Chartrian'. He dedicated his Cosmographia to Thierry of Chartres. While André Vernet estimated his lifespan as 1085-1178, the most certain date is 1147–48, when Cosmographia may have been read to Pope Eugene III. Evidence suggests he was born and taught in Tours due to detailed descriptions in Cosmographia. His major work, Cosmographia, is a prosimetrum on the creation of the world from a 12th-century Platonist viewpoint, noted for its allegorical use in discussing metaphysical and scientific questions, and influenced writers like Chaucer. It also showcased Christian neo-Platonism, prefigured in John Scotus Eriugena's Periphyseon. Bernardus also wrote the poems Mathematicus and possibly Experimentarius. Later medieval attributions include commentaries on Virgil's Aeneid and Martianus Capella's De Nuptiis Philologiae et Mercurii, though his authorship of the Aeneid commentary is debated. Modern scholars like Julian Ward Jones have analyzed the authorship, with some suggesting Bernardus Silvestris as the commentator. His work is praised for imaginative prose and its engagement with 12th-century intellectual controversies. William Turner noted a 'pantheistic drift' in his philosophy. Bernardus influenced numerous medieval and Renaissance authors, including Hildegard of Bingen, St. Bonaventure, Dante, and Boccaccio, and has been referenced in modern works by C. S. Lewis.
