Answer:
Wheatley's use of a break in the iambic meter, marked with a star, creates a momentary disruption in the flow of the poem's rhythm. This technique is known as a metrical substitution or a metrical variation.
In Wheatley's poem, this metrical variation occurs in lines 3 and 7, which are marked with a star (*). Here are those lines with the variations highlighted:
And, sighing, bid it [peaceful] rest
And, hush'd in [calm and silence] sleep.
These variations create a sense of hesitation or interruption in the poem's otherwise steady iambic meter. The effect is to draw attention to the words that are emphasized by the variation, in this case "peaceful" and "calm and silence."
The variation in line 3 ("And, sighing, bid it peaceful rest") emphasizes the idea of rest and peace, which is appropriate for a poem about death and mourning. The variation in line 7 ("And, hush'd in calm and silence sleep") similarly emphasizes the idea of calm and silence, which also fits with the poem's mournful tone.
By using these metrical variations, Wheatley is able to create a subtle shift in the poem's rhythm that draws attention to key words and ideas. This helps to reinforce the sense of sorrow and mourning that pervades the poem.
