The First Circle of Hell, Limbo, is home to pagans such as Virgil and many of antiquity's great writers and poets who died without knowing Christ. Following his encounters with Horace, Ovid, and Lucan, Dante enters the Second Circle of Hell, which is allotted for the sin of Lust. Here, he finds those guilty of lust by default - that is, unless they can prove their innocence in front of a jury of their peers - including Boniface, an early leader of Germany's Catholic Church. In order to be released from Hell, those convicted of Lust must engage in virtuous living and perform good works toward their fellow humans. If they fail to do so, they will be condemned to live out their lives in Limbo.
Dante believes those who die without accepting Jesus Christ will be held accountable for their actions after death and will either enter Heaven or Hell depending on their deeds. While in Hell, those who committed Lust will see others also made guilty by association; however, those who showed mercy toward them during life will be given priority by God when it comes time to decide where they will spend eternity.
Dante is able to leave Hell and travel back to Earth because God wants to save someone worthy of salvation. In this case, Dante volunteers himself so that others may be saved. When asked by Virgil if he is ready to leave Hell, Dante replies "Yes" and the two return to Earth.
The first circle of hell was Limbo. It is home to the Virtuous Pagans and Unbaptized Souls. Limbo was also the home of Virgil's soul before assisting Dante. Many believe that limbo is not actually located in hell, but rather somewhere between heaven and earth where souls go after they die.

The Hell's Nine Circles. When Beatrice landed in Hell, she begged the soul of Virgil, a pious Roman poet, to assist Dante in saving her. In exchange for his assistance, Beatrice pledged to laud Virgil in front of God once she was released from Hell. This is why the souls of those who died without repenting are placed in Limbo - until they are given permission to enter Heaven or Hell.
Virgil came to life again and traveled with Dante all over Hell and Purgatory. He was able to show them what crimes each of the nine circles of hell represents, and sometimes he would even lead them by the hand into deeper regions of the underworld. When their journey was finished, Virgil died again. But this time he did not go to Heaven or Hell - he stayed with Beatrice in Limbo until told that she needed him no longer. At this point, he returned to Earth.
Virgil has been praised by people throughout history for his role as Dante's guide. He is considered to be one of the most important poets in European literature.
Here is where things get a little confusing. Others believe it is one person who had multiple lives.
