Often centered around nature, these poems feature rhyming couplets (AB AB). This poem Ode on a Grecian Urn by John Keats is a perfect example. Here is a selection:
"Sylvan historian, who canst thus express
A flow'ry tale more sweetly than our rhyme:
What leaf-fring'd legend haunts about thy shape
Of deities or mortals, or of both,
In Tempe or the dales of Arcady?
What men or gods are these? What maidens loth?
What mad pursuit? What struggle to escape?
What pipes and timbrels? What wild ecstasy?" (3-10)
