What does the description of ozymandia's statue tell us about him

Here we have a speaker learning from a traveler about a giant, ruined statue that lay broken and eroded in the desert. The title of the poem informs the reader that the subject is the 13th-century B.C. Egyptian King Ramses II, whom the Greeks called “Ozymandias.” The traveler describes the great work of the sculptor, who was able to capture the king’s “passions” and give meaningful expression to the stone, an otherwise “lifeless thing.” The “mocking hand” in line 8 is that of the sculptor, who had the artistic ability to “mock” (that is, both imitate and deride) the passions of the king. The “heart” is first of all the king’s, which “fed” the sculptor’s passions, and in turn the sculptor’s, sympathetically recapturing the king’s passions in the stone.
