Alliteration is the repetition of the same consonant within close proximity. For example, "the six sisters seemed sad" shows alliteration by repetition of "s." Thus, the three lines that show alliteration are:
Doth ask a divine drink (repetition of "d")
But thou thereon didst only breathe (repetition of "th")
Since when it grows, and smells, I swear (repetition of "s")
