The variously titled fragment "Against Plato" or "De Universo", attributed to Hippolytus of Rome (c. 170 – c. 236), has the following: "And this is the passage regarding demons. But now we must speak of Hades, in which the souls both of the righteous and the unrighteous are detained. Hades is a place in the created system, rude, a locality beneath the earth, in which the light of the world does not shine; and as the sun does not shine in this locality, there must necessarily be perpetual darkness there. This locality has been destined to be as it were a guard-house for souls, at which the angels are stationed as guards, distributing according to each one's deeds the temporary punishments for characters. And in this locality there is a certain place set apart by itself, a lake of unquenchable fire, into which we suppose no one has ever yet been cast; for it is prepared against the day determined by God, in which one sentence of righteous judgment shall be justly applied to all. And the unrighteous, and those who believed not God, who have honoured as God the vain works of the hands of men, idols fashioned, shall be sentenced to this endless punishment. But the righteous shall obtain the incorruptible and un-fading kingdom, who indeed are at present detained in Hades, but not in the same place with the unrighteous."
