Like a gigantic circle of fire

 

The sun began to spin rapidly like a gigantic circle of fire.
Then it stopped momentarily, only to begin spinning vertiginously again.
Its rim became scarlet; whirling, it scattered red flames across the sky.
Their light was reflected on the ground, on the trees, on the bushes, and 
on the very faces and clothing of the people, 
which took on brilliant hues and changing colors.
After performing this bizarre pattern three times, 
the globe of fire seemed to tremble, shake,
and then plunge in a zigzag toward the terrified crowd. 
All this lasted about ten minutes.
Finally, the sun zigzagged back to its original place
and once again became still and brilliant, shining with its everyday brightness.
