A traveller tells how in the desert he saw the ruins of a colossal statue: two trunkless legs of stone and, half sunk in the sand, a shattered face with a sneer of cold command. On the pedestal, an inscription: «My name is Ozymandias, King of Kings; look on my works, ye Mighty, and despair.»
And around it nothing remains: only level sand as far as the eye can see. Shelley builds the whole sonnet so that the tyrant's boast — «despair before my greatness» — reads, centuries later, as its exact refutation. The power that thought itself eternal left nothing but a wreck in the desert.
