“In Dante’s Inferno – the first part of The Divine Comedy – the poet describes Hell as a series of nine concentric circles, each representing an order of wickedness greater than the one that preceded it until finally arriving at the center of the Earth, where Satan is imprisoned. One might imagine his depiction of Hell as something like an infernal, subterranean solar system with locked Hellish loops acting as parallel universes of sin under the relentless pressure of poetic justice revolving around the embodiment of evil. As one might expect, the Inferno is filled with images of fire – the classical elemental symbol long associated with divine wrath and punishment – with unsettling and supernatural, near-animistic qualities. In Canto XII, for example, those who’ve committed acts of violence are condemned to eternal immersion in the river Phlegethon, described by Dante as consisting of boiling blood, but originally imagined by the Greeks as a river of fire: the name itself means ‘flaming.’ His other Hells are no less unpleasant.
“Had Dante been allowed access to, say, radio telescopes and modern technology, he might well have imagined justice being meted out to souls trapped on Hellish exoplanets: intemperate places – some worlds of fire, others of ice – where not even the faintest idea of life can persist amidst cosmic severity. ” [. . .] –K.S.
