Answer and Explanation:
<em>Two vast and trunkless legs of stone</em>
<em>Stand in the desert . . . Near them, on the sand,</em>
<em>Half sunk, a shattered visage lies,</em>
<em />
<u>Percy Shelley's "Ozymandias" carries a message that existence and power are temporary.</u> In the excerpt above, only the legs remained of what once was a colossal statue of an ancient king. The power that king once had is now gone, along with his cities, subjects, and fortune.
<em>Round the decay</em>
<em>Of that colossal wreck, boundless and bare</em>
<em>The lone and level sands stretch far away.</em>
<em />
There is nothing left to remind us of the greatness that king once had except for the statue's remains. <u>This is a second message the poem conveys. Art, unlike life itself, is permanent.</u> The artistic representation of what that king once was is the only memory, able to "survive, stamped on these lifeless things."
