How does Apollonius of Rhodes use imagery in The Argonautika: The Story of Jason and the Quest for the Golden Fleece?

Imagery:

"They say that with the music of his [Orpheus] voice he enchanted stubborn mountain rocks and rushing streams. And testifying still to the magic of his song, there are wild oaks growing at Zone on the cost of Thrace, which he lured them down from Pieria with his lyre, rank upon rank of them, like soldiers on the march."

"Their blades were swallowed by the waves, and on either side the dark salt water broke into foam, seething angrily in answer to the strong men's strokes. The armour on the moving ship glittered in the sunshine like fire and all the time she was followed by a long white wake which stood out like a path across a green plain."
