Inferno is the first part of Italian writer Dante Alighieri's 14th-century narrative poem The Divine Comedy. It is followed by Purgatorio and Paradiso. The Inferno describes the journey of a fictionalised version of Dante himself through Hell, guided by the ancient Roman poet Virgil. In the poem, Hell is depicted as nine concentric circles of torment located within the Earth; it is the "realm ... of those who have rejected spiritual values by yielding to bestial appetites or violence, or by perverting their human intellect to fraud or malice against their fellowmen". As an allegory, the Divine Comedy represents the journey of the soul toward God, with the Inferno describing the recognition and rejection of sin.

In religion and folklore, hell is a location or state in the afterlife in which souls are subjected to punitive suffering, most often through torture, as punishment after death. Religions with a linear divine history often depict hells as eternal destinations, the biggest examples of which are Christianity and Islam, whereas religions with reincarnation usually depict a hell as an intermediary period between incarnations, as is the case in the Indian religions. Religions typically locate hell in another dimension or under Earth's surface. Other afterlife destinations include heaven, paradise, purgatory, limbo, and the underworld.
