Analyze the characteristics of Byron and Shelley's poetry creation.

Greek mythology is one of the important sources of European and American culture, a bright pearl in the world classical civilization, and occupies an extremely important position in the world cultural history. Greek mythology not only has a great influence on ancient Greek art, epic, tragedy, sculpture and painting, but also has a far-reaching influence on world literature, especially in the history of European and American literature. Many English romantic poets use a large number of Greek fairy tales and characters to express concrete and complex ideas, which are reflected in the creation of Keats, Shelley, Byron and other poets. This paper examines the Greek images contained in the poems of these three poets from the perspective of comparative literature. They not only touched the inner spirit of Greek mythology with their lives, but also embodied the eternal beauty of Greek mythology in their poetry creation, thus making their works have permanent charm.
