The afterglow is beautiful--that is what the elegy makes evident. It paints the beauty of sorrow. It is able to do so only because it contemplates the scene indirectly, as portrayed in the mirror of thought. An immediate vision of pain is itself wholly painful. If the agony is intense, and if no relief can be offered, we instinctively turn aside from the sickening sight. Only a brutalised people could find amusement in the ghastly spectacle of the Roman amphitheatre. It is cited as a proof of Domitian's diabolical cruelty that the emperor would have dying slaves brought before him in order that he might watch the facial expression of their last agonies. Such scenes are not fit subjects for art. The famous group of the _Laocoon_ is considered by many to have passed the boundaries of legitimate representation in the terror and torment of its subject; and _Ecce Homos_ and pictures of the crucifixion can only be defended from a similar condemnation when the profound spiritual significance of the subjects is made to dominate the bare torture. Faced squarely, in the glare of day, pain and death are grim ogres, the ugliness of which no amount of sentiment can disguise. You can no more find poetry in a present Inferno than flowers in the red vomit of a live volcano. Men who have seen war tell us they have discovered nothing attractive in its dreadful scenes of blood and anguish and fury. What could be more revolting to contemplate than the sack of a city,--fire and sword in every street, public buildings razed to the ground, honoured monuments defaced, homes ravaged, children torn from the arms of their parents, young girls dragged away to a horrible fate, lust, robbery, slaughter rampant without shame or restraint, the wild beast in the conquerors let loose, and a whole army, suddenly freed from all rules of discipline, behaving like a swarm of demons just escaped from hell. To think of cultivating art or poetry in the presence of such scenes would be as absurd as to attempt a musical entertainment among the shrieks of lost souls. The case assumes another aspect when we pass from the region of personal observation to that of reflection. There is no beauty in the sight of a captured castle immediately after the siege which ended in its fall, its battlements shattered, its walls seamed with cracks, here and there a breach, rough and ragged, and strewn with stones and dust. And yet, by slow degrees and in imperceptible ways, time and nature will transform the scene until moss-grown walls and ivy-covered towers acquire a new beauty only seen among ruins. Nature heals and time softens, and between them they throw a mantle of grace over the scars of what were once ugly, gaping wounds. Pain as it recedes into memory is transmuted into pathos; and pathos always fascinates us with some approach to beauty. If it is true that "Poets learn in sorrow what they teach in song,"
