Skeleton figurine in a robe with a scythe.
According to Wikipedia, Death has been personified as a figure or fictional character in mythology and popular culture since the earliest days of storytelling. Because the reality of death has had a substantial influence on the human psyche and the development of civilization as a whole, the personification of Death as a living, sentient entity is a concept that has existed in many societies since the beginning of recorded history. Oftentimes, death is shown as a skeletal figure carrying a large scythe, and wearing a midnight black gown with a hood or occasionally dressed in white, which is the traditional colour worn at funerals in many places.
In modern-day European-based folklore, Death is usually known as the "Grim Reaper" or "The grim spectre of death".
