What does the Dantes the divine comedey explain

The Divine Comedy is the allegorical record of Dante's quest to overcome sin and find God's love; in Inferno, Dante explores the nature of sin by traveling through Hell, where evil receives punishment according to God's justice.

Dante’s years of exile were years of difficult peregrinations from one place to another—as he himself repeatedly says, most effectively in Paradiso [XVII], in Cacciaguida’s moving lamentation that “bitter is the taste of another man’s bread and…heavy the way up and down another man’s stair.” Throughout his exile Dante nevertheless was sustained by work on his great poem. The Divine Comedy was possibly begun prior to 1308 and completed just before his death in 1321, but the exact dates are uncertain.
