Sordello is an example of those whom constant occupation in affairs of state had caused to defer any thought for spiritual things, and who are expiating the delay in the region outside the proper entrance to Purgatory. In Canto vii., after explaining that they will not be able to stir a step after sunset (“the night cometh when no man can work”), he leads the poets to a spot where they may pass the night. This is a flowery dell on the hillside, occupied by the spirits of those who in life had been sovereign princes and rulers. There they see the Emperor Rudolf and his adversary, Ottocar of Bohemia; Charles of Anjou, King of Naples and Sicily, Philip III. of France, Peter III. of Aragon, Henry III. of England, and many other famous men of the last generation. Sordello, in pointing them out, takes occasion to enlarge on the degeneracy of their sons, making a special exception in favour of Edward, son of Henry.
The sun sets (Canto viii.) and the shades join in the Compline hymn. At its conclusion, two angels clad in green robes descend, and take up their position on either side of the little valley. Dante, with his companions, goes down to join the “mighty shades,” and is met by one whom he at once recognises as an old friend, the Pisan noble Giovanni, or Nino de’ Visconti, “judge” or governor of the Sardinian province called Gallura, nephew of Count Ugolino. After some talk Dante notices the three stars spoken of above, and at the same moment Sordello draws Virgil’s attention to an “adversary.” They see a serpent making its way through the grass; and immediately the angels start in pursuit, putting it to flight. After this episode another shade announces himself as Conrad Malaspina, of the house with whom Dante was to find shelter during a part of his exile.
The night wears on, and Dante falls asleep (Canto ix.). He dreams that he is being carried by an eagle up to the empyrean heaven. On awaking he finds that the sun has risen some time, and learns from Virgil that at daybreak St. Lucy (who has already come under notice as taking an interest in his welfare) had appeared and borne him to the place where they now are, in front of the gate of Purgatory. This is approached by three steps of variously-coloured stone. The first is white marble, the second a dark and rough rock, the third blood-red porphyry, indicating probably the three stages of the soul’s progress to freedom through confession, contrition, and penance. On the topmost step sits an angel, who having marked seven P’s (peccata sins) on Dante’s forehead, admits them within the gate.
Thus far, except in the passage, Canto viii. 19 sqq., to which Dante himself draws the reader’s attention, the allegorical interpretation has not afforded any very great difficulty. With this particular passage readers will do well to compare Inf., ix. 37 sqq., where a very similar indication is given of an underlying allegory, and draw their own conclusions. But on the whole, the main interest of the first nine cantos of the Purgatory is more of a personal nature. Sordello alone may give an excuse for a good deal of historical research. For example, no one has yet explained Dante’s reasons for so distinguishing a person who, from all the records that we have, does not seem to have made any great figure in the eyes of his contemporaries.
It will hardly be necessary to follow Dante step by step through the stages of the mountain of purification. We shall probably do best to consider the general plan on which Purgatory is arranged, the nature of the various penances, with their adaptation to the offences which they expiate, and the light thrown in this division of the poem on Dante’s opinions about the elements of political and moral science.
We find, then, seven cornices, or ledges, on the mountain, connected with each other by stairways cut in the rock. Each stairway is guarded by an angel, and each, as it would appear, is shorter and less steep than the previous one. Thus the passage from the first to the second circle takes a considerable time, enough at all events to allow of some conversation between Dante and Virgil between the moment of their passing the angel and that at which they reach the top of the stairway. On the other hand, when they come to the final ascent, from the seventh circle to the level of the Earthly Paradise which occupies the summit, a few steps are sufficient to bring them to their halting-place, which, as appears afterwards, is practically on the summit level. Each angel, as Dante passes, erases from his forehead one of the P’s which the warder of the first gate had inscribed there, and utters one of the Scriptural Beatitudes appropriate to the circle which they are quitting. Thus, “Blessed are the peacemakers” accompanies their departure from the circle of the wrathful; “Blessed are they that hunger after righteousness” is heard as they leave that where gluttony is expiated.
The ritual, so to speak, is very precise throughout. Besides the Beatitudes, which are recited by the angel-guards, and in some cases it would seem repeated by a chorus of voices, we find in each circle commemoration variously contrived of notable instances, both of the sins punished and of their “contrary virtues.” These are perhaps worth going through in detail. In the circle of Pride, where it is necessary to go in a stooping posture, the pavement is engraved with representations of humility. The first is the Annunciation, (and here it should be noted that in every group an event from the life of the Virgin holds the first place); next comes David dancing before the Ark; and lastly, Trajan yielding to the widow’s prayer that he would perform an act of justice before setting out with the pomp of a military expedition. Further on in the same circle are found examples of the punishment of pride, taken alternately from Scripture and from classical mythology. The next circle is that of Envy. Here the penalty consists of the sewing up of the eyes, so that pictured representations would be of no use; and, accordingly, the task of calling the examples to mind is discharged by voices flying through the air. Yet another method is adopted in the third circle, where the Angry are punished by means of a dense smoke. Here the pictures are conveyed to Dante’s mind by a kind of trance or vision, in which he sees the various scenes. We must suppose that the spirits pass through some similar experience. In the fourth circle, the examples of activity and warnings against Sloth are delivered by the souls themselves. As it is night while Dante is in this circle, he is himself unable to move; but the discipline being to run at speed, the souls pass him in their course. The fifth circle, of the Avaricious and Prodigal, follows much the same rule as the fourth, except that here the instances of virtue are recited in the day, those of sin at night, so that Dante does not actually hear the latter. In this case the souls lie prostrate. The Gluttonous, in the sixth circle, are punished by having to pass under trees laden with fruit, which they cannot reach; and the examples and warnings are conveyed by voices among the branches of these trees. The seventh circle follows the fashion of the fourth, except that the souls (who are punished by fire for having in life failed to hold in due restraint the flames of passion) seem to address the warning reminiscences to each other as they meet in the circuit. An instance of the system on which the examples are introduced has been given from the first circle. Perhaps that for the sixth is even more typical. On first entering this they come to a tree, among the branches of which a voice is heard recording the conduct of the Virgin at the feast in Cana, when “she thought more of the success of the banquet than of her own mouth;” the custom of drinking only water prevalent among the Roman women, and the abstemiousness of Daniel and the Baptist. Then, after passing through a portion of the circle, and holding converse with its inmates, they reach another tree, from which a second voice comes to them bidding them remember the trouble that came from the drunkenness of the Centaur at the wedding of Pirithous, and the rejection by Gideon of the men who had drunk immoderately. This coupling of a classical and Scriptural instance is quite invariable.
To pass on to the subject of the light thrown upon Dante’s speculative views in the Purgatory. It is not too much to say that from that point of view it is the most important division of the whole poem. This, perhaps, follows naturally from its subject. The Purgatorial existence bears more affinity to the life of this world than does that of those who have reached their eternal abode; and human affections and human interests still have much of their old power. This, then, would naturally be the division in which questions arising from the conditions of man’s life with men would be likely to suggest themselves.
In the Hell we had indeed a statement of Dante’s view of Ethics, so far as was necessary to explain his attitude towards breaches of the moral law and their punishment. In the Purgatory he goes more deeply into the question, and expounds in Cantos xvi., xvii., and xviii., a theory with regard to the origin of morals and knowledge. According to this the soul when created is a tabula rasa, but having certain capacities inherent in it in consequence of the nature of its Creator. The Creator being absolutely veracious, the information imparted by the senses is infallible. Further, the Creator being absolutely happy, the soul naturally seeks happiness, and is said to love that in which it expects to find happiness. So far there is no room for error. Where it can come in is in the inferences which the mind draws from the information which the senses give, and in either its choice of an object to love, or the vigour with which it pursues that object. It must be further noted that the soul is endowed at the outset with a knowledge of good and evil, i.e. conscience, and with free-will; though this latter has to struggle with the conditions which the influence of the heavenly bodies imposes on the individual. With due culture, however, it can ultimately prevail over these; but it must also be aided in its struggle by the check of law and the guidance which should be afforded by spiritual pastors. In order that these may have their full effect, it is desirable that the secular and spiritual authorities should be in different hands: and thus we are brought to the same conclusions as in the treatise De Monarchia.
To return, however, to the moral question. All action, as has been said, is directed to an end, and (in the words of Aquinas, following Aristotle) the end for each individual is that which he desires and loves. If the end is rightly selected, and the love duly proportioned, the action does not incur blame. But it may happen that the end may be evil; in which case evil becomes the object of the love, or the love is turned to hatred. Now, no created being can hate its Creator, nor can any man hate himself; therefore the sins arising from this cause must be sins against fellow-men. These, so far as Purgatory is concerned, are pride, envy, anger, which, when carried into action, become the sins that are punished within the City of Dis, though in Purgatory they would appear on the whole to be regarded as the less grave offences.
