Analyze the poem "Ozymandias" by Percy Bysshe Shelley. What is the legacy that the king wants to leave behind, and how does he use language to portray this?

The king, Ozymandias, clearly wanted to be remembered as a powerful ruler. This is apparent in the language of the poem, stating that Ozymandias is a "king of kings." His reign seemed to be one of a standard of "cold command", which is apparent when Shelley describes his "shattered visage." While the empire that Ozymandias once ruled has now fallen, what remains is the memory of a ruthless, tyrannical ruler, left to bake in the desert.
