Final answer:
Part one of the Dante's 'Divine Comedy', which includes 'Purgatorio' and 'Paradiso', is called 'Inferno'. It's the realm of Hell where souls are punished, and Rodin's 'The Gates of Hell' is a sculptural interpretation of this part of the poem. Option 1 is the correct answer.
Step-by-step explanation:
The first part of the tripartite structure that includes "Purgatorio" and "Paradiso" is known as Inferno. This part of the epic poem, Dante's Divine Comedy, explores the realm of Hell, where souls face punishments that correspond to their sins on Earth. Famous artworks like 'The Gates of Hell' by Rodin visually interpret the vivid and tumultuous scenes described in Dante's Inferno.
The tripartite conception of the afterlife, with distinct areas for punishment, purification, and paradise, can be traced back to ancient philosophies and religions, which also influenced Dante's work. The idea that the afterlife is divided into realms such as Tartarus for sinners, the Elysian Fields for the virtuous, and a third realm for pure and heroic souls is common in ancient texts.
In conclusion, Part one is called Inferno, which is the correct option from the choices provided.
