Attraverso me è il modo in Inferno

CANTOS IV

Attraverso me è la strada per il primo cerchio: Limbo

The first circle, Limbo, is a region on the edge of hell. people who do not go to heaven even though they didn't sin. In christian mythology/ideology "Limbus" is a chamber or dungeon which you are to live eternally within, somewhat like a prison mimicking heaven; however, In Inferno, the poet's edition of this region is much nicer in retrospect compared to most. Dante's Limbo includes many non-Christian adults in addition to unbaptized babies. We also find many of the great heroes, philosophers, and creative minds of ancient Greece and Rome. We also find medieval non-Christians as Saladin, former Sultan of Egypt, and the famous Islamic philosophers Avicenna and Averroës. For Dante, Limbo found major figures from the Hebrew Bible, who were "liberated" by Jesus following his crucifixion. 

CANTOS V

Attraverso me è la strada per il secondo cerchio: Lust

Here Dante explores differences between love and lust. Between the overwhelming power of attraction toward the looks of a person and the carnal force of sexual desire. The lustful in hell, are according to Canto V "carnal sinners who subordinate reason to desire" . It appears that for Dante the line between lust and love is crossed when one acts on the sexual desire. Dante shows that this line is a very fine line, and he acknowledges the complexity of those who think of ideas and images of romantic love through their creative work; on the other hand, Dante's choice of lust as the first sin presented recalls the common association of sex with original sin with the fall of humankind in the garden of Eden. The punishment given here, in a poetic justice and ironic sense, is that each soul is blown back and forth in strong gusts of wind.

CANTOS VI

Attraverso me è la strada per il terzo cerchio: Gluttony

Gluttony is one of the seven deadly sins according to medieval Christian and church practice. Dante uses these sins as part of his organizational strategy. While lust and gluttony were generally considered the least serious of the seven sins, with pride almost always the worst.. The two were often viewed as closely related to one another, based on the biblical precedent of Eve "eating" the forbidden fruit and then successfully "tempting" Adam to do so. Based on the less than obvious perception of the gluttons and the content of Inferno VI, Dante appears to view gluttony as more complex than the usual understanding of the sin as excessive eating and drinking. Within this circle is the Cerberus who feeds on the souls of the gluttons.
