The metaphysics of light is, next to the metaphysics of love, one of the most important theoretical fundaments of the Italian Renaissance Platonist Marsilio Ficino (1433--1499). In his allegorical interpretations, light becomes an outstanding entity between things created and things divine.
Together with this, Sun, as the eminent bearer of light, receives a quasi divine and central role in such a measure that we can speak of a "metaphysical" or "semantic heliocentrism".
