The personification of Death as a living, sentient entity is a concept that has existed in many societies since the beginning of recorded history. In Western cultures, death is usually given the name "The Grim Reaper" and shown as a skeletal figure carrying a large scythe, and wearing a midnight black gown with a hood, or sometimes, a white burial shroud.

The earliest records of the Reaper date back to Greek civilization. Gaia and Uranus were Kronos' parents. Uranus, fearful of all his children including Kronos kept them constrained inside Gaia. Gaia wished to free her children and decided to give Kronos a sickle. With this sickle Kronos eventually castrated his father and bled him to death. Knowing how he had killed his father, once Kronos had children of his own, he feared his fate would be the same. As each child was born he swallowed them one by one.

From ancient folklore and other anthropological sources it is believed that Kronos was a harvest god worshipped by a culture before the Greeks. It is understood that his sickle was used in harvesting grain. Harvest was also associated with death because it signaled the end of the growing season and the beginning of Winter. Time devouring all things was represented poetically by Kronos eating his own children. It was the Greeks very dramatic way of saying nothing lasts forever.

The Grim Reaper wielding a sickle and, at times, an hourglass is directly derived from Kronos. One must understand how important grain was to these ancient civilizations. How horrible the thought of some mystic creature with the power to swipe away their whole harvest with a single swing of the mighty sickle. Not to mention the flock of famished crows, which would accompany such a terrible figure. It undoubtedly symbolized death in an extremely effective way. Though the Grim Reaper poses no real threat to our life, his legacy, which has been handed down from generation to generation, has instilled in us all the fear we need to ensure the desired effect. Hopefully, this answer aided you in understanding the significance of such a relevant myth.
