What literary technique does Dante heavily utilize throughout Inferno?

Dante heavily utilizes symbolism and allegory throughout "Inferno" to convey deeper moral and philosophical meanings. The structure of the work itself is symbolic, as the journey through Hell represents the soul's journey towards God, grappling with sin and redemption. Each circle of Hell corresponds to a specific vice, with the punishments being symbolic representations of the sins committed in life, reflecting the idea of poetic justice. This allegorical framework allows Dante not only to craft a vivid narrative but also to engage with complex themes such as justice, morality, and the nature of sin. The characters and their fates serve as symbols for broader human experiences and moral lessons, which is a hallmark of Dante's storytelling and a critical aspect of the epic's enduring impact.
