"Soaring fire that sways and sings,..."
See in text (Barter)
In this line, Teasdale uses strong alliteration. Three syllables begin with s, and all of them land on stresses. This technique of stringing together alliteration on three of the four stressed syllables of the line is typical of Anglo-Saxon verse. Teasdale uses beautiful sounds to more deeply convey the beauty of the image.
