Hesiod’s Theogony places Tartaros as a deep pit in the earth, a bronze-walled confinement below the ordinary dead. A Greek cosmogonic below, not Hades’ house and not a Christian hell.
Virgil’s Aeneid 6 walls Tartarus as the iron prison of the damned that Aeneas is shown and not entered. A named Roman epic below, not Hesiod’s cosmogonic pit, and not a Christian hell.
from Virgil · Aeneid, 19 BCE (unfinished at the poet’s death)
