Sonnet 2 begins with a military siege metaphor, something that occurs often in sonnets and poetry — from Virgil (‘he ploughs the brow with furrows’) and Ovid (‘furrows which may plough your body will come already’) to Shakespeare’s contemporary, Drayton, “The time-plow’d furrows in thy fairest field.” The image is used here as a metaphor for a wrinkled brow. Trenches are also carved into a field when a farmer plows, and the agricultural connotation is touched on two lines later with the image of worthless weeds.
