Works
Bernard's greatest work is the aforementioned Cosmographia, a prosimetrum on the creation of the world, told from a 12th-century Platonist perspective. The poem influenced Chaucer and others with its pioneering use of allegory to discuss metaphysical and scientific questions. Bernard also wrote the poem Mathematicus and probably the poem Experimentarius as well as some minor poems.
Among the works attributed to Bernard later in the Middle Ages were a commentary on Virgil's Aeneid (Bernard's authorship of which has been questioned by modern scholars) and a commentary on Martianus Capella's De Nuptiis Philologiae et Mercurii. The commentary on the Aeneid is the longest medieval commentary on that work, although it is incomplete, ending about two-thirds of the way through book six.
