Dante Alighieri wrote the Divine Comedy, an allegorical poem describing a journey through Hell (Inferno), Purgatory (Purgatorio), and Heaven (Paradiso). The poem consists of 100 cantos divided among the three sections. In Inferno, Dante is guided by Virgil through different circles of Hell punishing different types of sinners. Purgatorio depicts Purgatory as a mountain where souls cleanse themselves of sins. In Paradiso, Dante is guided by Beatrice through concentric circles representing planets and stars until reaching God.
