Quick Definition

Phlegethon is the fiery river of the Greek underworld, punishing perjurers and evildoers among the five infernal streams.

Detailed Definition
Phlegethon, one of the five rivers of Hades, flows with fire and leads to Tartarus. It appears in Virgil and Dante as a symbol of punishment. In poetry, it represents purgatorial suffering, the inescapable consequences of sin, and the infernal landscape of guilt.
Example
Example in poetry:
Phlegethon, river of fire in the underworld, appears in Virgil’s Aeneid VI; In Plato’s Phaedo, it’s one of the five infernal rivers; Ovid alludes to Phlegethon in Metamorphoses as a stream of punishment; Dante places Phlegethon in Inferno XII among violent sinners; Renaissance cosmology cites Phlegethon as a symbol of purgation; Modern verse uses Phlegethon to represent consuming guilt.
Additional Notes
Phlegethon, the river of fire in the Underworld, punishes oath-breakers and murderers; Dante places it in the seventh circle—its name means “flaming”—ideal for infernal or purgatorial imagery in poetry exploring guilt, eternal punishment, or volcanic metaphor.
