Bernardus Silvestris Orden de los libros

Cosmographia ("Cosmography"), also known as De mundi universitate ("On the totality of the world"), is a Latin philosophical allegory, dealing with the creation of the universe, by the twelfth-century author Bernardus Silvestris. In form, it is a prosimetrum, in which passages of prose alternate with verse passages in various classical meters. The philosophical basis of the work is the Platonism of contemporary philosophers associated with the cathedral school of Chartres—one of whom, Thierry of Chartres, is the dedicatee of the work. According to a marginal note in one early manuscript, the Cosmographia was recited before Pope Eugene III when he was traveling in France (1147–48). - Wikipedia
