How are the levels of Hell structured in Dante's Inferno?

The structure of the levels of Hell in Dante's "Inferno" is intricately designed to reflect a hierarchical order that corresponds to the severity of sins committed during one's lifetime. Dante's representation of Hell is divided into nine distinct circles, each one punishing different types of sins. As one descends deeper into Hell, the nature of the sins becomes increasingly grievous, culminating in the most severe transgressions at the center.

This hierarchy is not arbitrary; it is a deliberate reflection of Dante's moral philosophy, where sins are categorized primarily into three main types: incontinence (lack of self-control), violence, and fraud. Each circle manifests uniquely tailored punishments, known as contrapasso, that symbolize the nature of the sin itself and serve as a form of poetic justice. Therefore, the answer captures the essence of Dante's structured approach, showcasing how he meticulously constructed Hell to align with his moral and philosophical beliefs regarding sin and its consequences.
