What is the point of the view of the poem "ozymandias" and what effect does it have on who the reader hears

“Ozymandias” is a sonnet, a fourteen-line poem metered in iambic pentameter. The rhyme scheme is somewhat unusual for a sonnet of this era; it does not fit a conventional Petrarchan pattern, but instead interlinks the octave (a term for the first eight lines of a sonnet) with the sestet (a term for the last six lines), by gradually replacing old rhymes with new ones in the form ABABACDCEDEFEF.
