The Divine Comedy in the context of "Allegory in the Middle Ages"

Dis Pater (/ˌdɪs ˈpeɪtər/; Latin: [diːs patɛr]; genitive Ditis Patris, lit. the "Rich Patriarch"), otherwise known as Rex Infernus or Pluto, is a Roman god of the underworld. Dis was originally associated with fertile agricultural land and mineral wealth, and since those minerals came from underground, he was later equated with the chthonic deities Pluto (Hades) and Orcus.

Dis Pater's name was commonly shortened to Dis, and this name has since become an alternative name for the underworld or a part of the underworld, such as the City of Dis of Dante's The Divine Comedy, which comprises Lower Hell.

Inferno (Italian: [iɱˈfɛrno]; Italian for 'Hell') is the first part of Italian writer Dante Alighieri's 14th-century narrative poem The Divine Comedy, 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.

"Ulysses" is a poem in blank verse by the Victorian poet Alfred, Lord Tennyson (1809–1892), written in 1833 and published in 1842 in his well-received second volume of poetry. An oft-quoted poem, it is a popular example of the dramatic monologue. Facing old age, mythical hero Ulysses describes his discontent and restlessness upon returning to his kingdom, Ithaca, after his far-ranging travels. Despite his reunion with his wife Penelope and his son Telemachus, Ulysses yearns to explore again.

The Ulysses character (in Greek, Odysseus) has been widely examined in literature. His adventures were first recorded in Homer's Iliad and Odyssey (c. 800–700 BC), and Tennyson draws on Homer's narrative in the poem. Most critics, however, find that Tennyson's Ulysses recalls Dante's Ulisse in his Inferno (c. 1320). In Dante's re-telling, Ulisse is condemned to hell among the false counsellors, both for his pursuit of knowledge beyond human bounds and for creating the deception of the Trojan horse.
