In "Hellas" we find Shelley advocating the cause of Greece, and it is believed, that that poem assisted his friend Byron in the determination to wield his sword in the cause of Grecian Liberty. "The Revolt of Islam," his most mystical work, next to his early effort, "St. Irvyne, or the Rosicrucian," is full of the most majestic and sympathetic thoughts, and underlying its weirdness we have all those elements "which essentially compose a poem in the cause of a liberal and comprehensive morality, and with the view of kindling in the bosom of his readers a virtuous enthusiasm for those doctrines of liberty and justice, that faith and hope in something good, which neither violence, nor misrepresentation, nor prejudice, nor the continual presence and pressure of evil, can ever totally extinguish among mankind." Can we wonder that Shelley could be else than Republican when he regarded what Thackeray afterward summed up with biting irony, the record of the reigning house of Great Britain, the mad Guelph _Defenders of the Christian Faith_(_?_), the results of whose labors have been corroborated by Greville and recent writers? To what a line of monarchs, was Shelley called upon to give allegiance and prostrate himself before, and can we be astonished that he thus describes the state these abominable Hanoverians had "England in 1819:" "An old, mad, blind, despised and dying king,-- Princes the dregs of their dull race who flow Through public scorn, mud from a muddy spring,-- Rulers who neither see, nor feel, nor know, But leech-like to their fainting country cling, Till they drop blind in blood without a blow,-- A people starved and stabbed in unfilled field,-- An army which liberticide and prey Make as a two-edged sword to all who wield,-- Golden and sanguine laws which tempt and slay-- Religion Christless, Godless, a book sealed,-- A Senate--time's worst statute unrepealed,-- Are graves from which a glorious phantom may Burst to illumine our tempestuous day?" To aid Republicanism, he threw himself with fervor into the cause of the unhappy Caroline of Brunswick; and on her account he wrote "God Save the Queen," in imitation of the British national anthem, and the satirical piece entitled "Swellfoot, the Tyrant." In the following words he attacked the prime minister, Lord Castleragh, whose reactionary counsels were transforming England into a state analogous to that of Russia to-day: "Then trample and dance, thou oppressor, For thy victim is no redressor! Thou art sole lord and possessor Of her corpses, and clods and abortions--they pave Thy path to a grave."
