A holocaust is a religious animal sacrifice that is completely consumed by fire, also known as a burnt offering. The word derives from the ancient Greek holokaustos, the form of sacrifice in which the victim was reduced to ash, as distinguished from an animal sacrifice that resulted in a communal meal.
