According to Dante, then, the real subject of the Inferno is 'Man, as rendered liable, by ill desert in the exercise of his free will, to punishing justice.' Surely a subject fraught with unutterable sadness, compassed by impenetrable mystery, but one which in the hands of a prophet may well be made to yield the bread of life; a subject fitly introduced by those few pregnant words, 'The day was going, and the dusky air gave respite to the animals that are on earth from all their toils; and I alone girt me in solitude to bear the strain both of the journey and the piteous sight, which memory that errs not shall retrace.'[33] * * * * * Now if this be the true subject of the poem, it follows that all those physical horrors of which it seems almost to consist must be strictly subordinate to something else, must be part of the machinery or means by which the end of the poet is reached, but in no way the end itself. If the subject of the poem is a moral one, then the descriptions of physical torment and horror must never even for a moment overbalance or overwhelm the true 'motive' of the work, must never even for a moment so crush or deaden the feelings as to render them incapable of moral impressions, must never in a single instance leave a prevailingly physical impression upon the mind. And it is just herein that the transcendent power of the Inferno is displayed. Horrors which rise and ever rise in intensity till they culminate in some of the ghastliest scenes ever conceived by mortal brain are from first to last held under absolute control, are forced to support and intensify moral conceptions which in less mighty hands they would have numbed and deadened. Oh, the pity of this sin, the unutterable, indelible pity of it! Its wail can never be stilled in our hearts while thought and memory remain. The misery of some forms of sin, the foul shame of others, the vileness, the hatefulness, the hideous deformity of others yet--this, and not horror at the punishment of sin, is what Dante stamps and brands upon our hearts as we descend with him towards the central depths, stamps and brands upon our hearts till the pity, the loathing, the horror can endure no more;--then in the very depth of Hell, at the core of the Universe, with one mighty strain that leaves us well-nigh spent, we turn upon that central point, and, leaving Hell beneath our feet, ascend by the narrow path at the antipodes. With the horror and the burden of the starless land far off, we lift up our eyes again to see the stars, and our souls are ready for the purifying sufferings of Purgatory. * * * * *
