In this article we compare the images used by Dante Alighieri with the ones used by her/n“heretical” contemporary Marguerite Porete (†1310) for expressing the final contact-vision of God. We will analyze the use of the images of light, the gradual ascent and the knot in both/nauthors, putting it into the context of the theological doctrines about the visio Dei. This will allow us, in the first place, to claim a shared cultural background based in the conception of God as a visible being and, in the second, to discuss the historical implications of/nheteredoxy/ortodoxy in the Commedia and the Mirouer.
