What is the author's style in The Cossacks by Linda Pastan?

Known for her use of metaphor, Pastan uses powerful images in “The Cossacks” to portray death. The dominant metaphor in the poem is the representation of the Cossacks as death itself. It is a particularly strong metaphor because it reveals precisely how the speaker views death. Death has been portrayed in numerous ways by poets, and while others may see it variously as a peaceful figure, a welcome figure, or even a worthy adversary, Pastan's speaker views death as a ruthless mercenary who actively pursues her.
