What metaphors are used in Lake by Rosanna Warren?

In “Lake,” the language is predominantly straightforward and unadorned, with a splash of metaphor here and there to add intrigue. For instance, there is a lengthy description of the subject standing in waist-high water and then coming to shore to dry off the “cranky shoulder, cramping heel tendons, [and] bad knees.” These solely physical aspects are set against a more highbrow and obscure allusion to “ancient statues of Dionysus” as well as to the highly imagistic metaphor that concludes the poem.
