Tom Hanks returns to the Da Vinci Code franchise to play our favorite symbologist, Robert Langdon. Inferno, the title of the new film, comes from Dante Alighieri’s epic poem The Divine Comedy, part of which details the “inferno,” the Italian word for hell. But in this new film, we get a glimpse of Langdon’s past in the form of an unrequited love, Elizabeth Sinsky (Sidse Babett Knudsen). But Elizabeth isn’t just a random character Dan Brown made up — she’s inspired by Dante’s own muse and unrequited love, the real Beatrice Portinari. Beatrice has been the subject of numerous books and paintings, despite Dante only meeting her a few times. So, who was this enchanting mystery woman who stole Dante’s heart and inspired his epic poetry? Click through our slideshow to find out.
