What is spirit? What are our own minds, the portion of spirit with which we are best acquainted? We observe certain phenomena. We cannot explain them into material causes. We therefore infer that there exists something which is not material. But of this something we have no idea. We can define it only by negatives. We can reason about it only by symbols. We use the word: but we have no image of the thing; and the business of poetry is with images, and not with words. The poet uses words indeed; but they are merely the instruments of his art, not its objects. They are the materials which he is to dispose in such a manner as to present a picture to the mental eye. And if they are not so disposed, they are no more entitled to be called poetry than a bale of canvas and a box of colours to be called a painting.

Logicians may reason about abstractions. But the great mass of men must have images. The strong tendency of the multitude in all ages and nations to idolatry can be explained on no other principle. The first inhabitants of Greece, there is reason to believe, worshipped one invisible Deity. But the necessity of having something more definite to adore produced, in a few centuries, the innumerable crowd of gods and goddesses. In like manner the ancient Persians thought it impious to exhibit the Creator under a human form. Yet even these transferred to the Sun the worship which, in speculation, they considered due only to the Supreme Mind. The history of the Jews is the record of a continued struggle between pure Theism, supported by the most terrible sanctions, and the strangely fascinating desire of having some visible and tangible object of adoration. Perhaps none of the secondary causes which Gibbon has assigned for the rapidity with which Christianity spread over the world, while Judaism scarcely ever acquired a proselyte, operated more powerfully than this feeling. God, the uncreated, the incomprehensible, the invisible, attracted few worshippers. A philosopher might admire so noble a conception: but the crowd turned away in disgust from words which presented no image to their minds. It was before Deity embodied in a human form, walking among men, partaking of their infirmities, leaning on their bosoms, weeping over their graves, slumbering in the manger, bleeding on the cross, that the prejudices of the Synagogue, and the doubts of the Academy, and the pride of the portico, and the fasces of the Lictor, and the swords of thirty legions, were humbled in the dust. Soon after Christianity had achieved its triumph, the principle which had assisted it began to corrupt it. It became a new Paganism. Patron saints assumed the offices of household gods. St. George took the place of Mars. St. Elmo consoled the mariner for the loss of Castor and Pollux. The Virgin Mother and Cecilia succeeded to Venus and the Muses. The fascination of sex and loveliness was again joined to that of celestial dignity; and the homage of chivalry was blended with that of religion. Reformers have often made a stand against these feelings; but never with more than apparent and partial success. The men who demolished the images in cathedrals have not always been able to demolish those which were enshrined in their minds. It would not be difficult to show that in politics the same rule holds good. Doctrines, we are afraid, must generally be embodied before they can excite a strong public feeling. The multitude is more easily interested for the most unmeaning badge, or the most insignificant name, than for the most important principle.

From these considerations, we infer that no poet, who should affect that metaphysical accuracy for the want of which Milton has been blamed, would escape a disgraceful failure. Still, however, there was another extreme, which, though far less dangerous, was also to be avoided. The imaginations of men are in a great measure under the control of their opinions. The most exquisite art of poetical colouring can produce no illusion, when it is employed to represent that which is at once perceived to be incongruous and absurd. Milton wrote in an age of philosophers and theologians. It was necessary, therefore, for him to abstain from giving such a shock to their understandings as might break the charm which it was his object to throw over their imaginations. This is the real explanation of the indistinctness and inconsistency with which he has often been reproached. Doctor Johnson acknowledges that it was absolutely necessary that the spirit should be clothed with material forms. "But," says he, "the poet should have secured the consistency of his system by keeping immateriality out of sight, and seducing the reader to drop it from his thoughts." This is easily said; but what if Milton could not seduce his readers to drop immateriality from their thoughts? What if the contrary opinion had taken so fully possession of the minds of men as to leave no room even for the half belief which poetry requires? Such we suspect to have been the case. It was impossible for the poet to adopt altogether the material or the immaterial system. He therefore took his stand on the debatable ground. He left the whole in ambiguity. He has, doubtless, by so doing, laid himself open to the charge of inconsistency. But, though philosophically in the wrong, we cannot but believe that he was poetically in the right. This task, which almost any other writer would have found impracticable, was easy to him. The peculiar art which he possessed of communicating his meaning circuitously through a long succession of associated ideas, and of intimating more than he expressed, enabled him to disguise those incongruities which he could not avoid.

Poetry which relates to the beings of another world ought to be at once mysterious and picturesque. That of Milton is so. That of Dante is picturesque indeed beyond any that was ever written. Its effect approaches to that produced by the pencil or the chisel. But it is picturesque to the exclusion of all mystery. This is a fault on the right side, a fault inseparable from the plan of Dante's poem, which, as we have already observed, rendered the utmost accuracy of description necessary. Still it is a fault. The supernatural agents excite an interest; but it is not the interest which is proper to supernatural agents. We feel that we could talk to the ghosts and demons without any emotion of unearthly awe. We could, like Don Juan, ask them to supper, and eat heartily in their company. Dante's angels are good men with wings. His devils are spiteful ugly executioners. His dead men are merely living men in strange situations. The scene which passes between the poet and Farinata is justly celebrated. Still, Farinata in the burning tomb is exactly what Farinata would have been at an auto da fe. Nothing can be more touching than the first interview of Dante and Beatrice. Yet what is it, but a lovely woman chiding, with sweet austere composure, the lover for whose affection she is grateful, but whose vices she reprobates? The feelings which give the passage its charm would suit the streets of Florence as well as the summit of the Mount of Purgatory.

The spirits of Milton are unlike those of almost all other writers. His fiends, in particular, are wonderful creations. They are not metaphysical abstractions. They are not wicked men. They are not ugly beasts. They have no horns, no tails, none of the fee-faw-fum of Tasso and Klopstock. They have just enough in common with human nature to be intelligible to human beings. Their characters are, like their forms, marked by a certain dim resemblance to those of men, but exaggerated to gigantic dimensions, and veiled in mysterious gloom.

Perhaps the gods and demons of Æschylus may best bear a comparison with the angels and devils of Milton. The style of the Athenian had, as we have remarked, something of the Oriental character; and the same peculiarity may be traced in his mythology. It has nothing of the amenity and elegance which we generally find in the superstitions of Greece. All is rugged, barbaric, and colossal. The legends of Æschylus seem to harmonise less with the fragrant groves and graceful porticoes in which his countrymen paid their vows to the God of Light and Goddess of Desire, than with those huge and grotesque labyrinths of eternal granite in which Egypt enshrined her mystic Osiris, or in which Hindostan still bows down to her seven-headed idols. His favourite gods are those of the elder generation, the sons of heaven and earth, compared with whom Jupiter himself was a stripling and an upstart, the gigantic Titans, and the inexorable Furies. Foremost among his creations of this class stands Prometheus, half fiend, half redeemer, the friend of man, the sullen and implacable enemy of heaven. Prometheus bears undoubtedly a considerable resemblance to the Satan of Milton. In both we find the same impatience of control, the same ferocity, the same unconquerable pride. In both characters also are mingled, though in very different proportions, some kind and generous feelings. Prometheus, however, is hardly superhuman enough. He talks too much of his chains and his uneasy posture: he is rather too much depressed and agitated. His resolution seems to depend on the knowledge which he possesses that he holds the fate of his torturer in his hands, and that the hour of his release will surely come. But Satan is a creature of another sphere. The might of his intellectual nature is victorious over the extremity of pain. Amidst agonies which cannot be conceived without horror, he deliberates, resolves, and even exults. Against the sword of Michael, against the thunder of Jehovah, against the flaming lake, and the marl burning with solid fire, against the prospect of an eternity of unintermitted misery, his spirit bears up unbroken, resting on its own innate energies, requiring no support from anything external, nor even from hope itself.

To return for a moment to the parallel which we have been attempting to draw between Milton and Dante, we would add that the poetry of these great men has in a considerable degree taken its character from their moral qualities. They are not egotists. They rarely obtrude their idiosyncrasies on their readers. They have nothing in common with those modern beggars for fame, who extort a pittance from the compassion of the inexperienced by exposing the nakedness and sores of their minds. Yet it would be difficult to name two writers whose works have been more completely, though undesignedly, coloured by their personal feelings.

The character of Milton was peculiarly distinguished by loftiness of spirit; that of Dante by intensity of feeling. In every line of the Divine Comedy we discern the asperity which is produced by pride struggling with misery. There is perhaps no work in the world so deeply and uniformly sorrowful. The melancholy of Dante was no fantastic caprice. It was not, as far as at this distance of time can be judged, the effect of external circumstances. It was from within. Neither love nor glory, neither the conflicts of earth nor the hope of heaven could dispel it. It turned every consolation and every pleasure into its own nature. It resembled that noxious Sardinian soil of which the intense bitterness is said to have been perceptible even in its honey. His mind was, in the noble language of the Hebrew poet, "a land of darkness, as darkness itself, and where the light was as darkness." The gloom of his characters discolours all the passions of men, and all the face of nature, and tinges with its own livid hue the flowers of Paradise and the glories of the eternal throne. All the portraits of him are singularly characteristic. No person can look on the features, noble even to ruggedness, the dark furrows of the cheek, the haggard and woful stare of the eye, the sullen and contemptuous curve of the lip, and doubt that they belong to a man too proud and too sensitive to be happy.
