"Ozymandias" (pronounced /??zi'mændi.?s/) is a sonnet by Percy Bysshe Shelley, published in 1818 (see 1818 in poetry). It is frequently anthologised and is probably Shelley's most famous short poem. It was written in competition with his friend Horace Smith, who wrote another sonnet entitled "Ozymandias" seen below.
In addition to the power of its themes and imagery, the poem is notable for its virtuosic diction. The rhyme scheme of the sonnet is unusual and creates a sinuous and interwoven effect.
