It is important to keep in mind the point of view of “Ozymandias.” The perspective on the statue is coming from an unknown traveler who is telling the speaker about the scene. This helps create a sense of the mystery of history and legend: we are getting the story from a poet who heard it from a traveler who might or might not have actually seen the statue. The statue itself is an expression of the sculptor, who might or might not have truly captured the passions of the king. Our best access to the king himself is not the statue, not anything physical, but the king’s own words.
