Shelley belongs to the romantic school. Shelley (1792— 1822) is an English poet. Born into a noble family, he studied at Oxford University and was expelled for propagating atheism. Politically supported Irish national independence and praised the French Revolution. His poems are beautiful in tone, lively in rhythm and rich in imagination. Ode to the west wind and Ode to a Lark are world-famous. Prometheus Liberated is a typical positive romantic work. Romanticism came into being at the end of 18 and the beginning of 19. It is the product of the European bourgeois revolution in the climax years. Political opposition to feudal autocracy and artistic opposition to classicism belong to an ideology in the rising period of capitalism. European romanticism was born under the historical conditions that people were disappointed in the "kingdom of reason" in the Enlightenment, disillusioned with the slogan of "freedom, equality and fraternity" in the bourgeois revolution and dissatisfied with the capitalist social order. Due to the different class positions and political attitudes of writers, romanticism has formed two opposing factions: positive romanticism and negative romanticism. Active romantic writers criticize the darkness of society, aim at feudal aristocrats and oppose the residual feudal factors in capitalist society. At the same time, they also exposed all kinds of evil phenomena caused by the bourgeoisie itself and pinned their hopes on the future. Some writers are in favor of utopian socialism. Negative romantics yearn for the past, beautify the Middle Ages, and fantasize about seeking spiritual comfort and sustenance from ancient feudal society. The materials introduced are all positive romantic writers. The pros and cons of romanticism are mainly distinguished according to the political attitudes and social ideals of writers and works, but as the same literary trend of thought, they share the same basic characteristics, such as paying attention to lyricism, being good at using bold imagination and exaggeration, and persisting in shaping extraordinary characters, and so on.

The background of "Romantic" literature;

From the end of 18 to the beginning of 19, under the impact of the French Revolution and the Napoleonic Wars, European revolutions and wars were frequent and turbulent. Political darkness and social inequality make people feel that the capitalist system established after the French Revolution is far from as beautiful as described by the enlightenment thinkers. All social strata, especially intellectuals, actively pursue new ideals and express their personal feelings. This social emotion is reflected in the field of literary creation, resulting in romantic literature.
