This paper departs from biblical images of creation (wisdom, word, mirror), and goes on to consider those images in three medieval thinkers from the Neoplatonist tradition. Firstly, Johannes Scotus Eriugena, who uses sapientia and in principio images. Secondly, St Hildegard of Bingen, in whose visions the images of wisdom and mirror-God appear. In third place, M. Eckhart, who refers in his Latin writings to God’s creation in se ipso. The article will try to show that a common feature regarding creatio can be found in all the three authors: the explanation of the origin of the world as manifestation of the first principle and the final return–union–to it. This subject has recently been partly dealt with by authors such as W. Beierwaltes, W. Otten or M. Marder. The present research follows the thread of previous studies, claiming at the same time to be an original contribution to the history of Neoplatonic thought about creation.
