Question

what is the significance of desert in the poem ozymandias

Answer 1

It signifies that no one now with him, he is left alone no matter how big his dynasty and empire was.

Answer 2

The desert, not Ozymandias, is thus the most powerful tyrant in Shelley's poem. It is “boundless” and “stretch[es] far away” as though it has conquered everything the eye can see, just as it has conquered Ozymandias's statue. Ozymandias may be the king of kings, but even kings can be toppled by mere grains of sand.
