Which traitor is chewed in Lucifer's central mouth in the Inferno?

Judas Iscariot is chewed in Lucifer’s central mouth in Dante’s Inferno. He occupies the most prominent of Lucifer’s three mouths because his betrayal of Christ represents treachery against divine authority.

Dante places Lucifer at the center of the frozen Ninth Circle, the lowest region of Hell. Rather than ruling a fiery kingdom, Satan is trapped in ice and beats enormous wings that intensify the freezing wind. His three faces and three mouths parody the imagery of the Trinity while embodying monstrous inversion.

The other two mouths contain Brutus and Cassius, the assassins of Julius Caesar. Dante treats their murder of Caesar as betrayal of the Roman imperial order, while Judas’s betrayal is directed against Christ. Sinon is punished among the falsifiers, not in Lucifer’s jaws. The scene therefore combines theology and politics: Judas symbolizes treason against God, while Brutus and Cassius symbolize treason against worldly government.
