"Bright Star" is a sonnet written by the Romantic poet John Keats as a homage to his beloved Fanny Brawne.
It is primarily made up of two analogies. The first analogy is a negative one, where the poet describes the aspect of the star that he doesn’t wish to resemble. The second analogy is a positive one, where the poet explains the aspect of the star that he aspires to be like — namely, steadfast loyalty to his beloved.
