can you PLEASE list 3 literary techniques used in the passage below and answer a question? (another passage)

the passage is:

"The desert he rode was red and red the dust he raised, the small dust that powdered the legs of the horse he rode, the horse he led. In the evening a wind came up amd reddened all the sky before him. There were few cattle in that country because it was barren country indeed yet he came at evening upon a solitary bull rolling in the dust against the bloodred sunset like an animal in sacrificial torment. The bloodred dust blew down out of the sun. He touched the horse with his heels and rode on. He rode with the sun coppering his face and the red wind blowing out of the west across the evening land and the small desert birds flew chittering among the dry bracken and horse and rider and horse passed on and their long shadows passed in tandem like the shadow of a single being. Passed and paled into the darkening land, the world to come."
