God

"Some of the pilgrims behind the stretcher carried his arms- two shotguns, a heavy rifle, and a light revolver carbine- the thunderbolts of that pitiful Jupiter. " (55)

Jupiter was a powerful god of the sky from Greek mythology, who had power over men and other gods. Jupiter used lightening as a weapon. Kurtz is a symbol for a god, because he has guns and is civilized. The guns seem like magic to the savages, so he seems mighty to them.
