Abstract

A reading of the Divina Commedia with the eyes of a modern scientist reveals that Dante devoted great attention to the description of a wide variety of natural phenomena, particularly those involving astronomy, optics and geometry. A remarkable case is the structure of the cosmos emerging from the Paradiso, which foreshadows a non-Euclidean geometrical structure with remarkable similarities to Einstein’s 1917 static cosmological solution. Such model, however, as well as other solutions with positive spatial curvature, are ruled out by current astrophysical observations. Here I discuss Dante’s geometric intuition and show its close analogy with the shape of the observable cosmic space-time in the standard CDM expanding model, fully supported by present-day cosmological data.
