Immortalization is impossible..even for the "King of Kings."

Shelley's sonnet "Ozymandias" is clearly about a King who has tried to immortalize himself, as well as his "significance" and his power, and ironically all that is left are the ruins of his rein. I believe that the speaker has put this writing in third person to almost exaggerate the irony. He explains in lines 4-5 the face of the King (on the statue) and how serious the King is portrayed with a "wrinkled lip, and sneer of cold command." He also goes on to say " And on the pedestal, these words appear: / My name is Ozymandias, King of Kings, / Look on my Works, ye Mighty, and despair! " This shows the power which the king once held. Kind of like saying "look at what I've created and rule and will always rule." Then we are reminded that "Nothing beside remains. Round the decay / Of that colossal Wreck, boundless and bare. " Shelley is sure to make it clear that everything the King built has all decayed. I also think the reason he is exaggerating the fall of the King's rein is because, although his power was thought to be immortalized with his statue, it wasn't because of the constant changing world we all live in. He makes this point in "Mutability" also ( that change is constant ). The only thing that never changes in this world is change itself.
