Ozymandias

"'My name is Ozymandias, king of kings; Look on my works, ye Mighty, and despair!'"

This Ozymandias guy seems like a tyrant, a former one to be specific.  He is said to have a "sneer of cold command," pointing to the tyranny of his order, and that he mocked "them" with his hand, "them" meaning his subjects.  I find it a little funny the Situational Irony in the poem.  On a pedestal, Ozymandias proclaims his glory and might.  Now, this once mighty and feared tyrant lay dead, killed by the sands of time.  It is ironic that the pedestal still proclaims his glory, though he is no more than a visage.   I think the theme of the poem is a scorn for tyranny.  The poem illustrates the once powerful tyrant Ozymandias as being nothing anymore, but a visage.  The speaker is emphasizing the tyrant's weakness and vulnerability, though many tyrants in old times proclaimed to be gods.
