A devil is the personification of evil as it is conceived in many and various cultures and religious traditions. It is seen as the objectification of a hostile and destructive force. It is difficult to specify a particular definition of any complexity that will cover all of the traditions, beyond that it is a manifestation of evil. It is meaningful to consider the devil through the lens of each of the cultures and religions that have the devil as part of their mythos. The history of this concept intertwines with theology, mythology, psychiatry, art and literature, maintaining a validity, and developing independently within each of the traditions. It occurs historically in many contexts and cultures, and is given many different names -Satan, Lucifer, Beelzebub, Mephistopheles - and attributes: It is portrayed as blue, black, or red; It is portrayed as having horns on its head, and without horns, and so on. The idea of the devil has been taken seriously often, but not always, for example when devil figures are used in advertising and on candy wrappers.
