Answer:
The central image of the poem "Ozymandias" by Percy Bysshe Shelley is a collapsed statue in the desert. The statue is a representation of the once-great pharaoh Ozymandias, who was once a powerful ruler but is now forgotten and his legacy crumbled into ruins. The statue's shattered visage with its "frown, / And wrinkled lip, and sneer of cold command" symbolizes the transience of human power and the inevitability of the downfall of all things, no matter how grand they may seem at the moment.
