Inferno: Canto 26 - The False Flames

In this canto, Dante and Virgil climb out of the pit of the thieves and approach the eighth ditch of the 8th circle of the Inferno, where fire itself becomes the instrument of punishment. Here, Dante will behold flickering tongues of flame that speak without mouths — and one mysterious double flame that burns unlike the others. What it reveals offers both wonder and caution.
