What metaphors are used in Big Black Good Man by Richard Wright?

Wright's story is rich in figurative language, particularly similes and metaphors that emphasize Olaf's view of Jim as something inhuman. When Jim first appears, the narrator describes him as Olaf sees him: "His chest bulged like a barrel; his rocklike and humped shoulders hinted of mountain ridges; the stomach ballooned like a threatening stone; and the legs were like telephone poles." In these phrases, Jim is a force of nature or an inanimate object. In many other descriptions, he is an animal, with a "buffalo like head," a neck "like a bull's," "gorilla like arms," "mammoth hands," and so on. Jim is repeatedly described as anything and everything except a human being.
