What best states the theme of Ozymandias?

The tomb of the Egyptian King Ramses Second is

described in a Latin book as the tomb of Ozymandias. During the

First century, the Greek historian Siculus has recorded that the

biggest statue in Egypt had these Words inscribed on it: I am

Ozymandias, King of Kings; if any one wishes to know who I am and

where I lie, let him surpass me in some of my exploits. Today we

will wonder how haughty that man might have been! Shelley did not

visit Egypt but read about these records and vividly describes the

fallen ruins of this statue as if he has actually seen it. The legs

alone stand erect and the upper portion has fallen and is almost

buried in the desert sands, the head and the body separated. The

cruel passions of this tyrant are still to be seen there on that

ruined stony face, as was really intended by the sculptor. Not one

of the various monuments erected by the King around his statue

survived. Everything except that cruel face were destroyed and

buried by Time and the desert wind. The message conveyed through

the poem is that "the glories of our blood and state are shadows.

They are not substantial things. Even kingly authority has to come

down to earth, to be made equal to everything else."
