Concerning the inquiry whether hell is at or near the centre of the earth, my opinion is that nothing should be rashly asserted, not least because Augustine reckoned that nobody knows where hell is. The lower regions can mean whatever is meant by the term “inferior”. . . For myself I do not believe that man can know the position of hell.
--St. Thomas Aquinas, Declaratio xxxvi Quaestionum ad Lectorem Venetum, 24, 25.
