Byron's friend, Percy Bysshe Shelley (1792-1822), was also in fiery revolt against all conventions and institutions, though his revolt proceeded not, as in Byron's case, from the turbulence of passions which brooked no restraint, but rather from an intellectual impatience of any kind of control. He was not, like Byron, a sensual man, but temperate and chaste. He was, indeed, in his life and in his poetry, as nearly a disembodied spirit as a human creature can be. The German poet, Heine, said that liberty was the religion of this century, and of this religion Shelley was a worshiper. His rebellion against authority began early. He refused to fag at Eton, and was expelled from Oxford for publishing a tract on the _Necessity of Atheism_. At nineteen, he ran away with Harriet Westbrook, and was married to her in Scotland. Three years later he deserted her for Mary Godwin, with whom he eloped to Switzerland. Two years after this his first wife drowned herself in the Serpentine, and Shelley was then formally wedded to Mary Godwin. All this is rather startling, in the bare statement of it, yet it is not inconsistent with the many testimonies that exist to Shelley's singular purity and beauty of character, testimonies borne out by the evidence of his own writings. Impulse with him took the place of conscience. Moral law, accompanied by the sanction of power, and imposed by outside authority, he rejected as a form of tyranny. His nature lacked robustness and ballast. Byron, who was at the bottom intensely practical, said that Shelley's philosophy was too spiritual and romantic. Hazlitt, himself a Radical, wrote of Shelley: "He has a fire in his eye, a fever in his blood, a maggot in his brain, a hectic flutter in his speech, which mark out the philosophic fanatic. He is sanguine-complexioned and shrill-voiced." It was, perhaps, with some recollection of this last-mentioned trait of Shelley the man, that Carlyle wrote of Shelley the poet, that "the sound of him was shrieky," and that he had "filled the earth with an inarticulate wailing."
His career as a poet began, characteristically enough, with the publication, while at Oxford, of a volume of political rimes, entitled _Margaret Nicholson's Remains_, Margaret Nicholson being the crazy woman who tried to stab George III. His boyish poem, _Queen Mab_, was published in 1813; _Alastor_ in 1816, and the _Revolt of Islam_--his longest--in 1818, all before he was twenty-one. These were filled with splendid, though unsubstantial, imagery, but they were abstract in subject, and had the faults of incoherence and formlessness which make Shelley's longer poems wearisome and confusing. They sought to embody his social creed of perfectionism, as well as a certain vague pantheistic system of belief in a spirit of love in nature and man, whose presence is a constant source of obscurity in Shelley's verse. In 1818 he went to Italy, where the last four years of his life were passed, and where, under the influences of Italian art and poetry, his writing became deeper and stronger. He was fond of yachting, and spent much of his time upon the Mediterranean. In the summer of 1822 his boat was swamped in a squall, off the Gulf of Spezzia, and Shelley's drowned body was washed ashore, and burned in the presence of Byron and Leigh Hunt. The ashes were entombed in the Protestant cemetery at Rome, with the epitaph, _Cor cordium_.
