What was 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! Shelley did not visit Egypt but read about these 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 almost is 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 substancial things. Even kingly authority has to come down to earth, to be made equal to everything else."
