What is the general idea of each part of Dante's poems and what is the overall explanation?

This paper expounds that Dante resolutely opposed obscurantism and pursued the truth in the Middle Ages, which had a far-reaching influence on later European poetry creation. This poem describes Dante himself. He lost his way in a dark forest near Jerusalem. At dawn, he walked out of the forest and came to a sunny hill. Suddenly, leopards, lions and wolves blocked the way. At the critical moment, Virgil, an ancient Roman poet, came to the rescue and guided him to visit the ninth floor of hell to punish the sinners before they died, and the seventh floor of purgatory to repent and purify his soul.

General idea: hell:

Hell is shaped like a funnel and divided into nine layers.

On the first floor, there is a strong wind, and people born before the baptism of Christianity are waiting for punishment. Socrates, Plato, Homer, etc.

The second layer is the biting cold, in which a person succumbs to lewdness, becomes romantic and forgets reason before he dies. There are also ancient Spartan queen Helen, Carthage queen Jude and so on.

The third layer is cold and rainy, and the monster tears the foul soul of indulgence with its claws. The fourth layer is the ghost of profligacy, greed and profit.

The fifth floor is a dark lake, where violent creatures bite each other and bleed profusely.

On the sixth floor, there are many graves, coffins are on fire, and cult leaders and congregations are roasted to scream.

On the seventh floor, tyrants and thugs were boiled in the boiling blood lake; Suicide with weak belief becomes a gray tree with cancer; Blasphemy, usury and exploitation accept fire, rain, heat and sand.

There are ten evil ditches on the eighth floor. Those who cheated before their death, such as seducers, flatterers, hypocrites, thieves and instigators, were all punished.

The ninth floor is a dirty ice lake with Satan at its center.

Purgatory:

Purgatory, also known as the pure land world, repents people who have committed minor crimes. There are seven deadly sins in life: arrogance, jealousy, anger, laziness, greed, food and lust.

Heaven:

Finally, in the paradise at the top of the mountain, Bayar Cai Li, the poet's young lover, was surrounded by angels and led the poet to visit the cloud nine.

There is a cloud nine in the sky, and a gentleman lives in the moon; People who do good live in mercury; Caring people live in Venus; Sun Ri, philosopher and theologian; Martyrs live on Mars; The upright people live in Jupiter, and the devout practitioners live in Saturn; Our virgin lives in the starry sky; God and angels live in the crystal sky. Heaven is magnificent, colorful, full of love and joy.

On the eighth day, Dante accepted the inquiries of three saints about the virtues of faith, hope and love, and entered the mysterious and beautiful sky.
