Upon entering the fourth circle, Dante and Virgil encounter the Hoarders and the Wasters, who spend eternity rolling giant boulders at one another.
They move to the fifth circle, the marsh comprising the river Styx, where Dante is accosted by a Florentine, Filippo Argenti; he is amongst the Wrathful that fight and battle one another in the mire of the Styx.
The city of Dis begins Circle VI, the realm of the violent. The poets enter and find themselves in Circle VI, realm of the Heretics, who reside among the thousands in burning tombs. Dante stops to speak with two sinners, Farinata degli Uberti, Dante's Ghibelline enemy, and Cavalcante dei Cavalcanti, father of Dante's poet friend, Guido.
The poets then begin descending through a deep valley. Here, they meet the Minotaur and see a river of boiling blood, the Phlegethon, where those violent against their neighbors, tyrants, and war-makers reside, each in a depth according to their sin.
Virgil arranges for the Centaur, Nessus, to take them across the river into the second round of circle seven, the Suicides. Here Dante speaks with the soul of Pier delle Vigne and learns his sad tale.
In the third round of Circle VII, a desert wasteland awash in a rain of burning snowflakes, Dante recognizes and speaks with Capaneus, a famous blasphemer. He also speaks to his beloved advisor and scholar, Brunetto Latini. This is the round held for the Blasphemers, Sodomites, and the Usurers.
