Sometimes the tortures of the damned are a mere physical translation, so to speak, of their crimes. Thus the ruthless disseminators of strife and dissension who have torn asunder those who belonged one to another, those who had no proper existence apart from one another, are in their turn hewn and cleft by the avenging sword; and ever as their bodies reunite and their wounds are healed, the fierce blow falls again. Amongst them Dante sees the great troubadour Bertram de Born, who fostered the rebellion of the sons of our own king Henry II. In that he made father and son each other's enemy, his head is severed from his trunk, his brain from its own root.[34] In other cases a transparent metaphor or allegory dictates the form of punishment; as when the hypocrites crawl in utter weariness under the crushing weight of leaden garments, shaped like monkish cloaks and cowls, and all covered with shining gold outside.[35] Or when the flatterers and sycophants wallow in filth which fitly symbolises their foul life on earth.[36] It is probable that some special significance and appropriateness might be traced in almost all the forms of punishment in Dante's Hell, though it is not always obvious. But one thing at least is obvious: the uniform congruousness of the impression which the physical and moral factors of each description combine to produce. In fact, the Inferno is an account of 'man, as deserving ill by the exercise of his free will,' in which all the external surroundings are brought into precise accord with the central conception. The tortures are only the background; and as in the picture of a great artist, whether we can trace any special significance and appropriateness in the background or not, we always feel that it supports the true subject of the picture and never overpowers it, so it is here. Man as misusing his free will. This is the real subject of the Inferno. All else is accessory and subordinate. But if this be so, we should expect to find an endless variety and gradation, alike of guilt and punishment, as we pass through the circles of Hell. And so we do. At one moment indignation and reproof are all swallowed up in pity, and the suffering of the exiled soul only serves to quicken an infinite compassion in our hearts, a compassion not so much for the punishment of sin as for sin itself with its woeful loss and waste of the blessings and the holiness of life. At another moment we are brought face to face with a wretch whose tortures only serve to throw his vileness into sharper relief; and when we think of him and of his deeds, of him and of his victims, we can understand those awful words of Virgil's when Dante weeps, 'Art thou too like the other fools? The death of pity is true pity here.'[37] Infinite pity would indeed embrace the most abandoned, but it is only weak and misdirected pity that wakes or slumbers at the dictate of mere suffering.
