This passage from Morte d'Arthur (1485) by Sir Thomas Mallory is an example of poetic phrasing.
Poetic phrasing alludes to the use of grammar, syntax and rhythmic patterns used in poetry in order to organize the movement and harmony of the text. The use of certain words and their disposition in the text will have an effect on the sense of pace, meter and rhythm, and the impetus of the poem.
But in this example, poetic phrasing goes beyond the use of certain patterns for rhythm and rhyme. Here, the poetic phrasing also emphasizes the sound and emotional impact of the text and the events being described, making use of powerful words with a strong figurative meaning that can be understood when combined.
