Death Personification

In English, death is often given the name the "Grim Reaper" and shown as a skeletal figure carrying a large scythe, and wearing a midnight black gown, robe or cloak with a hood, or sometimes a white burial shroud. Usually when portrayed in the black-hooded gown, his face is not to be seen, but is a mere shadow beneath the hood.
In some cases, the Grim Reaper is able to actually cause the victim's death, leading to tales that he can be bribed, tricked, or outwitted in order to retain one's life. Other beliefs hold that the Spectre of Death is only a psychopomp, serving only to sever the last tie from the soul to the body and guide the deceased to the next world and having no control over the fact of their death.
