While the sinners represent man's imperfections, Virgil symbolizes human reason. Throughout the poem, Virgil uses logic and reason to convince the monsters to allow him to gain passage to the various circles of Hell. The use of characters and mentors is distinct in each piece. The one freed prisoner attempts to become a mentor to the others but fails. As he tries to enlighten the remaining prisoners he is received with anger and threats.
Nothing is learned about the characters as individuals.
They remain nameless, faceless images. In contrast, there are numerous characters in the Inferno. The sinners are arranged in a hierarchy. In each group of sinners, Dante distinguishes a few characters. Virgil acts as Dante's mentor and guide, leading him through the intricate levels of Hell.
