Imagery in Poetry Excerpt

Read the following excerpt from a poem:

"The sun dipped low, a blazing sphere,

Its golden rays spilling warmth across the field,

Where daisies painted the earth, white and pure.

In the distance, the mountains stood solemn,

Like ancient guardians wrapped in mist,

As shadows danced softly in the cooling air."
