What is the structure of the poem?

"Ozymandias" is a fourteen-line, iambic pentameter sonnet. It is not a traditional one, however. Although it is neither a Petrarchan sonnet nor a Shakespearean sonnet, the rhyming scheme and style resemble a Petrarchan sonnet more, particularly with its 8-6 structure rather than 4-4-4-2.
