What lines in the ruined city show past splendors of city?

In "Ozymandias," the shattered visage lies "half sunk/A shattered visage lies, whose frown, and wrinkled lip/And sneer of cold command, tell that its sculptor well those passions read/Which yet survive, stamped on these lifeless things./The hand, that mocked them, and the heart, that fed"

These lines indicate the city's past splendor through the imposing visage of Ozymandias, which despite being shattered, still conveys the arrogance and power of the long-lost ruler. The frown, wrinkled lip, and sneer of cold command suggest a formidable ruler who inspired both fear and respect. Furthermore, the hand that mocked the sculptor's art and the heart that fueled the ruler's actions are described as surviving through these lifeless remains, showcasing the endurance of Ozymandias's legacy.
