so perfectionized as to be able to expel evil from his own nature, and from the greater part of the creation, was the cardinal point of his system. And the subject he loved best to dwell on was the image of One warring with the Evil Principle, oppressed not only by it, but by all—even the good, who were deluded into considering evil a necessary portion of humanity; a victim full of fortitude and hope and the spirit of triumph emanating from a reliance in the ultimate omnipotence of Good. Such he had depicted in his last poem, when he made Laon the enemy and the victim of tyrants. He now took a more idealized image of the same subject. He followed certain classical authorities in figuring Saturn as the good principle, Jupiter the usurping evil one, and Prometheus as the regenerator, who, unable to bring mankind back to primitive innocence, used knowledge as a weapon to defeat evil, by leading mankind, beyond the state wherein they are sinless through ignorance, to that in which they are virtuous through wisdom. Jupiter punished the temerity of the Titan by chaining him to a rock of Caucasus, and causing a vulture to devour his still-renewed heart. There was a prophecy afloat in heaven portending the fall of Jove, the secret of averting which was known only to Prometheus; and the god offered freedom from torture on condition of its being communicated to him. According to the mythological story, this referred to the offspring of Thetis, who was destined to be greater than his father. Prometheus at last bought pardon for his crime of enriching mankind with his gifts, by revealing the prophecy. Hercules killed the vulture, and set him free; and Thetis was married to Peleus, the father of Achilles.

Shelley adapted the catastrophe of this story to his peculiar views. The son greater than his father, born of the nuptials of Jupiter and Thetis, was to dethrone Evil, and bring back a happier reign than that of Saturn. Prometheus defies the power of his enemy, and endures centuries of torture; till the hour arrives when Jove, blind to the real event, but darkly guessing that some great good to himself will flow, espouses Thetis. At the moment, the Primal Power of the world drives him from his usurped throne, and Strength, in the person of Hercules, liberates Humanity, typified in Prometheus, from the tortures generated by evil done or suffered. Asia, one of the Oceanides, is the wife of Prometheus—she was, according to other mythological interpretations, the same as Venus and Nature. When the benefactor of mankind is liberated, Nature resumes the beauty of her prime, and is united to her husband, the emblem of the human race, in perfect and happy union. In the Fourth Act, the Poet gives further scope to his imagination, and idealizes the forms of creation—such as we know them, instead of such as they appeared to the Greeks. Maternal Earth, the mighty parent, is superseded by the Spirit of the Earth, the guide of our planet through the realms of sky; while his fair and weaker companion and attendant, the Spirit of the Moon, receives bliss from the annihilation of Evil in the superior sphere.

Shelley develops, more particularly in the lyrics of this drama, his abstruse and imaginative theories with regard to the Creation. It requires a mind as subtle and penetrating as his own to understand the mystic meanings scattered throughout the poem. They elude the ordinary reader by their abstraction and delicacy of distinction, but they are far from vague. It was his design to write prose metaphysical essays on the nature of Man, which would have served to explain much of what is obscure in his poetry; a few scattered fragments of observations and remarks alone remain. He considered these philosophical views of Mind and Nature to be instinct with the intensest spirit of poetry.

More popular poets clothe the ideal with familiar and sensible imagery. Shelley loved to idealize the real—to gift the mechanism of the material universe with a soul and a voice, and to bestow such also on the most delicate and abstract emotions and thoughts of the mind. Sophocles was his great master in this species of imagery.

I find in one of his manuscript books some remarks on a line in the "Oedipus Tyrannus", which show at once the critical subtlety of Shelley's mind, and explain his apprehension of those 'minute and remote distinctions of feeling, whether relative to external nature or the living beings which surround us,' which he pronounces, in the letter quoted in the note to the "Revolt of Islam", to comprehend all that is sublime in man.

'In the Greek Shakespeare, Sophocles, we find the image,

Pollas d' odous elthonta phrontidos planois:

a line of almost unfathomable depth of poetry; yet how simple are the images in which it is arrayed!

"Coming to many ways in the wanderings of careful thought."

If the words odous and planois had not been used, the line might have been explained in a metaphorical instead of an absolute sense, as we say "WAYS and means," and "wanderings" for error and confusion. But they meant literally paths or roads, such as we tread with our feet; and wanderings, such as a man makes when he loses himself in a desert, or roams from city to city—as Oedipus, the speaker of this verse, was destined to wander, blind and asking charity. What a picture does this line suggest of the mind as a wilderness of intricate paths, wide as the universe, which is here made its symbol; a world within a world which he who seeks some knowledge with respect to what he ought to do searches throughout, as he would search the external universe for some valued thing which was hidden from him upon its surface.'

In reading Shelley's poetry, we often find similar verses, resembling, but not imitating the Greek in this species of imagery; for, though he adopted the style, he gifted it with that originality of form and colouring which sprung from his own genius.

In the "Prometheus Unbound", Shelley fulfils the promise quoted from a letter in the Note on the "Revolt of Islam". (While correcting the proof-sheets of that poem, it struck me that the poet had indulged in an exaggerated view of the evils of restored despotism; which, however injurious and degrading, were less openly sanguinary than the triumph of anarchy, such as it appeared in France at the close of the last century. But at this time a book, "Scenes of Spanish Life", translated by Lieutenant Crawford from the German of Dr. Huber, of Rostock, fell into my hands. The account of the triumph of the priests and the serviles, after the French invasion of Spain in 1823, bears a strong and frightful resemblance to some of the descriptions of the massacre of the patriots in the "Revolt of Islam".) The tone of the composition is calmer and more majestic, the poetry more perfect as a whole, and the imagination displayed at once more pleasingly beautiful and more varied and daring. The description of the Hours, as they are seen in the cave of Demogorgon, is an instance of this—it fills the mind as the most charming picture—we long to see an artist at work to bring to our view the

'cars drawn by rainbow-winged steeds
Which trample the dim winds: in each there stands
A wild-eyed charioteer urging their flight.
Some look behind, as fiends pursued them there,
And yet I see no shapes but the keen stars:
Others, with burning eyes, lean forth, and drink
With eager lips the wind of their own speed,
As if the thing they loved fled on before,
And now, even now, they clasped it. Their bright locks
Stream like a comet's flashing hair: they all
Sweep onward.'

Through the whole poem there reigns a sort of calm and holy spirit of love; it soothes the tortured, and is hope to the expectant, till the prophecy is fulfilled, and Love, untainted by any evil, becomes the law of the world.

England had been rendered a painful residence to Shelley, as much by the sort of persecution with which in those days all men of liberal
