From the extreme edge of the firmament, Hildegard contemplates the wheel of creation that springs from the heart of God, a cosmological instrument in which mankind resides, described in size and proportions, and in the internal movements of the soul and the body. This is the scenario in the Book of Divine Works. It is a long sequence of ten scenes that invites human beings to climb the road of virginitas, towards the re-composition of their own selves in union with the divine Caritas.
