We cannot miss the general comment on human vanity in the poem. It is not just the “mighty” who desire to withstand time; it is common for people to seek immortality and to resist death and decay. Furthermore, the sculptor himself gets attention and praise that used to be deserved by the king, for all that Ozymandias achieved has now “decayed” into almost nothing, while the sculpture has lasted long enough to make it into poetry. In a way, the artist has become more powerful than the king. The only things that “survive” are the artist’s records of the king’s passion, carved into the stone.
