The final five lines mock the inscription hammered into the pedestal of the statue. The original inscription read “I am Ozymandias, King of Kings; if anyone wishes to know what I am and where I lie, let him surpass me in some of my exploits.” The idea was that he was too powerful for even the common king to relate to him; even a mighty king should despair at matching his power. That principle may well remain valid, but it is undercut by the plain fact that even an empire is a human creation that will one day pass away. The statue and surrounding desert constitute a metaphor for invented power in the face of natural power. By Shelley’s time, nothing remains but a shattered bust, eroded “visage,” and “trunkless legs” surrounded with “nothing” but “level sands” that “stretch far away.” Shelley thus points out human mortality and the fate of artificial things.
