Fearing that this son of his second marriage might also be taken from him, Shelley left his native country, never to return. At the time when the Lord Chancellor was branding him as less fit for the most rudimentary duties of social life than any other man in England, he was preparing to prove that he was one of the few men then in existence who were predestined to immortality. He left England, stamped as a criminal, and most of the Englishmen whom he met abroad feared and hated him as capable of any crime. He appears to have been actually once or twice subjected to personal molestation.

As already mentioned, Shelley in 1817 published a pamphlet on the subject of Parliamentary Reform. As a proof of the moderation and practicability of the views elaborated in its pages, it need only be mentioned that the Tories in 1867 passed almost the very scheme of Reform which the "atheist and republican" had planned fifty years before. He "disavowed any wish to establish universal suffrage at once, or to do away with monarchy and aristocracy." And on many other occasions he declared himself to be against precipitate changes. His Radicalism consisted simply in his being fifty years ahead of his day.

Attacked and persecuted by the narrow-minded society of the period, Shelley now hurled his poems of liberty at England. His political poems are written with his blood. The employment of such similes for Castlereagh and Sidmouth as "two bloodless wolves whose dry throats rattle" and "two vipers tangled into one," was allowable in his case. It must not be forgotten that to him Castlereagh, Sidmouth, and Eldon, were not men, but personifications of a principle—of the great, fateful principle of reaction to which his career and his happiness had been sacrificed. He writes in The Masque of Anarchy:

"I met Murder on the way—
He had a mask like Castlereagh.
Very smooth he looked, yet grim;
Seven bloodhounds followed him.
. . . . . . . . . . . . . .
Clothed with the bible as with light,
And the shadows of the night,
Like Sidmouth next, Hypocrisy
On a crocodile came by.
. . . . . . . . . . . . . .
One fled past, a maniac maid,
And her name was Hope, she said,
But she looked more like Despair;
And she cried out in the air:
'My father Time is weak and grey
With waiting for a better day;
See how idiot-like he stands,
Fumbling with his palsied hands!
'He has had child after child,
And the dust of death is piled
Over every one but me—
Misery! oh Misery!'"

It was not, however, only in bellicose lyrics that Shelley incorporated his political and social ideas and passions at this period. In the year 1818 he wrote two very characteristic narrative poems, Julian and Maddalo and Rosalind and Helen. The first-mentioned gives a vivid description of the poet's life in Venice with Byron, and affords one of the many proofs of his noble and ardent admiration for Byron's poetry. It contains an account of a visit paid by the two friends to a lunatic asylum in the neighbourhood of Venice and describes the impression produced upon Shelley. The man "whose heart a stranger's tear might wear as water-drops the sandy fountain-stone," and who "could moan for woes which others hear not," could not but be deeply moved by compassion for the unfortunates who at that time were still kept in fetters and punished by flogging.

We gain the best idea of the utter want of understanding of mental disease in those days, and the barbarity displayed in its treatment, from reading of the manner in which an insane patient of such rank as King George the Third was treated in 1798. The King's mental alienation displayed itself chiefly in excessive talkativeness; there was no inclination to any kind of violence. Nevertheless from the very beginning, and throughout the whole duration of the attack, he was kept in a strait-waistcoat, was closely confined, deprived of the use of knife and fork, and subjected to the whims of his pages, who knocked him about, struck him, and used abusive language to him. All this is known because the King retained a distinct remembrance after his recovery of what had happened during his illness.

Shelley's gentleness and love of his fellow-men are evident in the plea which he, ignorant of the humaner treatment of the insane inaugurated in France during the Revolution, utters for these afflicted ones:

"Methinks there were
A cure of these with patience and kind care,
If music thus can move."

The second poem, Rosalind and Helen, which gives a powerful general impression of the misery which prejudice and intolerance have brought upon the human race, has not hitherto been properly understood or valued according to its deserts. It attempts to give a comprehensive representation of all that truly good and liberal-minded human beings have to suffer from antiquated ideas and principles in combination with human malignity. We have the description of a father who was a coward to the strong, a tyrant to the weak; hard, selfish, false, rapacious; the torturer of his wife and terror of his children, who became pale and silent if they heard, or thought they heard, his footstep on the stair. He dies, and Rosalind, the mother, is distressed because her children involuntarily rejoice at their father's death, and because she herself cannot but feel it to be a relief. The dead man had been strictly orthodox. He has, as it appears when his will is read, decreed that the children shall inherit nothing if they continue to live with their mother, because she secretly holds the Christian creed to be false, and he must save his children from eternal fire. The mother feels that she must leave her children. "Thou know'st," she says—

"Thou know'st what a thing is poverty
Among the fallen on evil days.
'Tis crime, and fear, and infamy,
And houseless want in frozen ways
Wandering ungarmented, and pain,
And, worse than all, that inward stain,
Foul self-contempt, which drowns in sneers
Youth's starlight smile, and makes its tears
First hot like gall, then dry for ever.
And well thou know'st a mother never
Could doom her children to this ill,—
And well he knew the same."
