. In the final stanza, the speaker again addresses the urn itself, saying that it, like Eternity, "doth tease us out of thought." He thinks that when his generation is long dead, the urn will remain, telling future generations its enigmatic lesson: "Beauty is truth, truth beauty." The speaker says that that is the only thing the urn knows, and the only thing it needs to know. Form "Ode on a Grecian Urn" follows the same Ode-stanza structure as the "Ode on Melancholy," though it varies more the rhyme scheme of the last three lines of each stanza. Each of "Grecian Urn"'s five stanzas is ten lines long, metered in a relatively precise iambic pentameter, and divided into a two part rhyme scheme, the last three lines of which are variable. The first seven lines of each stanza follow an ABABCDE rhyme scheme, but the second occurrences of the CDE sounds do not follow the same order. In stanza one, lines seven through ten are rhymed DCE; in stanza two, CED; in stanzas three and four, CDE; and in stanza five, DCE, just as in stanza one. As in other odes (especially "Autumn" and "Melancholy"), the two-part rhyme scheme (the first part made of AB rhymes, the second of CDE rhymes) creates the sense of a two-part thematic structure as well. The first four lines of each stanza roughly define the subject of the stanza, and the last six roughly explicate or develop it. (As in other odes, this is only a general rule, true of some stanzas more than others; stanzas such as the fifth do not connect rhyme scheme and thematic structure closely at all.) Themes If the "Ode to a Nightingale" portrays Keats's speaker's engagement with the fluid expressiveness of music, the "Ode on a Grecian Urn" portrays his attempt to engage with the static immobility of sculpture. The Grecian urn, passed down through countless centuries to the time of the speaker's viewing of it, exists outside of time in the human sense--it does not age, it does not die, and ind...
