"Ozymandias" sounds a lot like the conclusion of a Shakespearean tragedy; the final lines of the poem are especially reminiscent of something you might hear as the curtain is about to fall at the end of the play, or as the credits are about to roll at the end of a sad movie. The way in which the poem emphasizes destruction and barrenness makes it read like something you'd hear at Ozymandias's funeral. The last lines in particular call attention to the poem's themes in a really catchy way (note all those memorable, alliterative phrases!), making the poem seem very much like those last words you hear as you're about to leave the theater.
