 Literary critics such as David Schalkwyk see this sonnet as playing out a relationship with unequal power.He sees this relationship in Sonnets 26, 57, 58 and notes that it is strongest in 57 saying "This sonnet's hyperbolic reference to slavery invokes more clearly the late-sixteenth-century, almost wholly pejorative sense of vassalage...".With the first lines of the sonnet being, "Being your slave what should I do but tend Upon the hours, and times of your desire?"
