For 17 years of his life, the exact whereabouts of the medieval Italian poet Dante Alighieri are unknown to modern scholars. It is known that during this time he traveled as an exile across Europe, working on his epic poem, The Divine Comedy. In his masterpiece he describes a journey through the three realms of the afterlife. During his lost wanderings, Dante stumbled upon an infestation of the living dead. The unspeakable acts he witnessed became the basis of all the horrors described in Inferno.
