¶ … poetry of John Keats inspires readers because of their lyricism, accessibility, and imagery. Many of Keats' poems focus on beauty as subject and theme, for beauty is a source of inspiration. Flowers and other natural objects like birds, trees, and supernatural creatures appear frequently in the works of John Keats to convey the theme of beauty. As one of the threads tying Keats' poems together, the theme of beauty emerges in several of his more famous works, including "Ode to a Nightingale," "Ode on a Grecian Urn," and "Ode on Melancholy."

Greek gods and goddesses are immortal ideals of human beauty, and Keats evokes them to create a sense of timelessness. Furthermore, this timeless quality shared by the gods and the urn itself is an essential quality of beauty. Beauty is as timeless as the gods and as long-lasting as the Grecian urn.
