Cosmographia
Bernard Silvestris
 The work is divided into two parts: "Megacosmus", which describes the ordering of the physical universe, and "Microcosmus", which describes the creation of man. 1 (verse): Natura (Nature) complains to Noys (Divine Providence; Greek ) that Hyle (Primordial Matter; Greek ), although held in check by Silva (the Latin equivalent of hyle), is chaotic and unformed and asks that Noys impose order and form on the confused matter. 2 (prose): Noys reveals her status as the daughter of God and asserts that the time is right for Natura's plea to be granted. She then separates out the four elements of fire, earth, water, and air from primordial matter. Seeing that the results are good, she begets the World Soul, or Endelechia, as a bride for Mundus (World). Their marriage is the source of life in the universe. 3 (verse): This long poem in elegiac couplets presents the results of the ordering of the universe. Ether, the stars and sky, the earth, and the sea have become distinguished, and the nine orders of angels attend on the God who exists outside the universe. There follows a catalogue of the stars and constellations, along with the planets and their natures. Then the earth and its creatures are described, with catalogues of mountains, beasts, rivers, plants (which are treated in particularly loving detail), fish, and birds. 4 (prose): The relationships between the powers operating in the universe are analyzed. All things under the heavens form part of a cosmic cycle, controlled by Natura, which will never cease, since its maker and cause are eternal. Hyle is the basis, whom the rational plan of God and Noys has ordered in an everlasting system, although subject to time: "For as Noys is forever pregnant of the divine will, she in turn informs Endelechia with the images she conceives of the eternal patterns, Endelechia impresses them upon Nature, and Nature imparts to Imarmene [Destiny; Greek ] what the well-being of the universe demands." 1 (prose): Noys displays the created universe to Natura and points out its various features. 2 (verse): With the work of Noys, Silva has recovered her true beauty. Noys (still speaking to Natura) declares herself proud of the harmony she has brought to the universe. 3 (prose): Noys says that for the completion of the cosmic design, the creation of man is needed. For this it is necessary that Natura seek out Urania (the celestial principle) and Physis (the material principle). Natura sets forth and searches through various regions of the heavens. When she reaches the outermost limit of the heavens, she encounters the Genius whose responsibility it is to delineate the celestial forms on the individual things of the universe. He greets Natura and points out Urania, whose brightness dazzles Natura. 4 (verse): Urania agrees to descend to Earth and collaborate in the creation of man. She will take with her the human soul, guiding it through all the heavens so that it may become acquainted with the laws of fate and learn the rules that govern its behavior. 5 (prose): To gain the sanction of the divine powers, Natura and Urania travel outside the cosmos, to the sanctuary of the supreme divinity, Tugaton (the Good; Greek ), whose favor they pray for. They then descend, one by one, through the planetary spheres. 6 (verse): Having reached the lower boundary of the sphere of the Moon, where the quintessence meets the terrestrial elements, Natura pauses to look about her. 7 (prose): Natura and Urania see thousands of spirits. Urania tells Natura that, in addition to the angels who dwell beyond the created universe and in the heavenly spheres, there are spirits below the Moon—some good, some evil. 8 (verse): Urania bids Natura to review the totality of the universe and note the principles of divine concord that it manifests. 9 (prose): Natura and Urania descend to Earth and reach a secluded locus amoenus (called Gramision or Granusion—the readings of the manuscripts are disputed). There they meet Physis, accompanied by her daughters Theorica (Contemplative Knowledge) and Practica (Active Knowledge), who is rapt in contemplation of created life in all its aspects. Suddenly, Noys appears. 10 (verse): Noys explains that Natura, Urania, and Physis can collaborate to complete the creation by fashioning a creature who participates in both the divine and earthly realms. 11 (prose): Noys assigns Urania, Physis, and Natura specific tasks in the creation of man, providing a model for each. Urania, using the Mirror of Providence, is to provide him with a soul derived from Endelechia; Physis, using the Book of Memory, is to provide him with a body; and Natura, using the Table of Destiny, is to unite the soul and the body. 12 (verse): Natura summons her two companions to begin the work. Physis, however, is somewhat angry, since she sees that matter is ill suited for the fashioning of a being that requires intellect. Urania assists her by eliminating the evil taint from Silva and containing the matter within definite limits. 13 (prose): Physis—making use of the imperfect aspects of Silva that had (somewhat uncertainly) submitted to the will of God and had been left over from the rest of creation—fashions a body. The four humors are described, along with the tripartite division of the body into the head (seat of the brain and the sensory organs), the breast (seat of the heart) and the loins (seat of the liver). 14 (verse): The powers of the senses and the brain, heart, and liver are detailed. The organs of generation will prevent human life from wholly passing away and the universe from returning to chaos.
