A demon is a supernatural evil or malicious spirit. The word demon was first used in the New Testament, from the Greek word daemon, δαίμονες or δαιμόνια. In various cultures demons are still feared within popular superstition.

Demons in the Hebrew Bible

Demons in the Hebrew Bible are usually not the same as "demons" as commonly understood today by Christians. The demons mentioned in the Bible are of two classes, the "se'irim" and the "shedim." The se'irim ("hairy beings"), to which some Israelites sacrificed in the open fields are satyr-like demons, described as dancing in the wilderness (Isa. xiii. 21, xxxiv. 14), and are identical with the jinn of the Arabian woods and deserts. Possibly to the same class belongs Azazel, the goat-like demon of the wilderness (Lev. xvi. 10 et seq.), probably the chief of the se'irim, and Lilith (Isa. xxxiv. 14). Possibly "the roes and hinds of the field," by which Shulamit conjures the daughters of Jerusalem to bring her back to her lover (Cant. ii. 7, iii. 5), are faunlike spirits similar to the se'irim, though of a harmless nature.

The (Job v. 23) "stones of the field"), with which the righteous are said to be in league, seem to be field-demons of the same nature. The wilderness as the home of demons was regarded as the place whence such diseases as leprosy issued, and in cases of leprosy one of the birds set apart to be offered as an expiatory sacrifice was released that it might carry the disease back to the desert (Lev. xiv. 7, 52)

Possibly the evil spirit that troubled Saul (I Sam. xvi. 14 et seq.) was originally a demon, turned into an evil spirit coming from God in the amended Masoretic text. None of these demons, however, has actually a place in the system of Biblical theology; it is God alone who sends pestilence and death. The shedim are "not gods" (Deut. xxxii. 17); there is no supernatural power beyond God (Deut. iv. 35.)

It is possible, however, that, as at a later stage in the development of Judaism the idols were regarded as demons, so the Canaanite deities were, either in disparagement, or as powers seducing men to idolatry, called "shedim" by the sacred writers (Deut. xxxii. 17; Ps. cv. 37); all the more so as the latter ascribed a certain reality to the idols (Ex. xii. 12; Isa. xix. 1, xxiv. 21.)

Influences from Chaldean mythology

In Chaldean mythology the seven evil deities were known as "shedim," storm-demons, represented in ox-like form; and because these oxcolossi representing evil demons were, by a peculiar law of contrast, used also as protective genii of royal palaces and the like, the name "shed" assumed also the meaning of a propitious genius in Babylonian magic literature (see Delitzsch, "Assyrisches Handwörterb." pp. 60, 253, 261, 646; Jensen, "Assyr.-Babyl. Mythen und Epen," 1900, p. 453; Sayce, l.c. pp. 441, 450, 463; Lenormant, l.c. pp. 48-51).

It was from Chaldea that the name "shedim" = evil demons came to the Israelites, and so the sacred writers in tentionally applied the word in a dyslogistic sense to the Canaanite deities 'in the two passages quoted. But they also spoke of "the destroyer" () Ex. xii. 23) as a demon whose malignant effect upon the houses of the Israelites was to be warded off by the blood of the paschal sacrifice sprinkled upon the lintel and the door-post (a corresponding pagan talisman is mentioned in Isa. lvii. 8). In II Sam. xxiv; 16 and II Chron. xxi. 15 the pestilence-dealing demon is called = "the destroying angel" (compare "the angel of the Lord" in II Kings xix. 35; Isa. xxxvii. 36), because, although they are demons, these "evil messengers" (Ps. lxxviii. 49; A. V. "evil angels") do only the bidding of God, their Master; they are the agents of His divine wrath.

There are indications that popular Hebrew mythology ascribed to the demons a certain independence, a malevolent character of their own, because they are believed to come forth, not from the heavenly abode of God, but from the nether world (compare Isa. xxxviii. 11 with Job xiv. 13; Ps. xvi. 10, xlix. 16, cxxxix. 8).

In Jewish rabbinic literature

Rabbinical demonology has three classes of, demons, though they are scarcely separable one from another. There were the "shedim," the "mazziḳim" (harmers), and the "ruḥin" (evil spirits). Besides these there were "lilin" (night spirits), "ṭelane" (shade, or evening, spirits), "ṭiharire" (midday spirits), and "ẓafrire" (morning spirits), as well as the "demons that bring famine" and "such as cause storm and earthquake" (Targ. Yer. to Deut. xxxii. 24 and Num. vi. 24; Targ. to Cant. iii. 8, iv. 6; Eccl. ii. 5; Ps. xci. 5, 6.)

In the main demons were workers of harm. To them were ascribed the various diseases, particularly such as affect the brain and the inner parts. Hence there was a fear of "Shabriri" (lit. "dazzling glare"), the demon of blindness, who rests on uncovered water at night and strikes those with blindness who drink of it (Pesachim 112a; Avodah Zarah 12b); also mentioned were the spirit of catalepsy and the spirit of headache, the demon of epilepsy, and the spirit of nightmare,

These demons were supposed to enter the body and cause the disease while overwhelming or "seizing" the victim. To cure such diseases it was necessary to draw out the evil demons by certain incantations and tailsmanic performances, in which the Essenes excelled. Josephus, who speaks of demons as "spirits of the wicked which enter into men that are alive and kill them," but which can be driven out by a certain root ("B. J." vii. 6, § 3), witnessed such a performance in the presence of the emperor Vespasian ("Ant." viii. 2, § 5), and ascribed its origin to King Solomon.

The King and Queen of Demons

In some sources, the demons were believed to be under the dominion of a king or chief, either Ashmodai (Targ. to Eccl. i. 13; Pes. 110a; Yer. Shek. 49b) or, in the older Haggadah, Samael ("the angel of death"), who kills people by his deadly poison, and is called "head of the devils". Occasionally a demon is called "satan": "Stand not in the way of an ox when coming from the pasture, for Satan dances between his horns" (Pes. 112b; compare B. Ḳ. 21a).

The queen of demons is Lilith, pictured with wings and long flowing hair, and called the "mother of Ahriman" ( B. B. 73b; 'Er. 100b; Nid. 24b). "When Adam, doing penance for his sin, separated from Eve for 130 years, he, by impure desire, caused the earth to be filled with demons, or shedim, lilin, and evil spirits" (Gen. R. xx.; 'Er. 18b.)

Though the belief in demons was greatly encouraged and enlarged in Babylonia under the influence of Parsee notions, demonology never became an essential feature of Jewish theology. The reality of demons was never questioned by the Talmudists and late rabbus; most accepted their existence as a fact. Nor did most of the medieval thinkers question their reality. Only rationalists likeMaimonides and Abraham ibn Ezra, clearly denied their existence. Their point of view eventually became the mainstream Jewish understanding.

In the New Testament and Christianity

This word has a number of meanings, all related to the idea of a spirit that inhabited a place, or that accompanied a person. Whether such a daemon was benevolent or malevolent, the Greek word most meant something different from the later medieval notions of 'demon', and scholars debate the time in which first century usage by Jews and Christians in its original Greek sense became transformed to the later medieval sense.

Saint Augustine's reading of Plotinus, in City of God (ch.11) is a case in point. Augustine's text is ambiguous as to whether daemons had become 'demonized' by the early 5th century:

"He (Plotinus) also states that the blessed are called in Greek eudaimones, because they are good souls, that is to say, good demons, confirming his opinion that the souls of men are demons.' —''City of God, ch. 11.—Of the Opinion of the Platonists, that the Souls of Men Become Demons When Disembodied.

If Augustine meant 'demons' in the later, medieval sense, the passage would savor of rehetorical casuistry that is not characteristic of him.

According to Christian doctrine, When God created angels, he offered them the same choice he was to offer humanity: follow, or be cast apart from him. Some angels chose not to follow God, instead choosing the path of evil. One of these angels desired to be as powerful as God, and seduced a host of his companions to follow him against their ruler, to become himself the new sovereign. This rebellious angel was named Satan (lit. "adversary").

Satan and his host declared war with God, but God's army, commanded by the archangel Michael, defeated the rebels. Their defeat was never in question, since God is by nature omnipotent, but Michael was given the honor of victory in the natural order. God then cast his enemies from Heaven to the abyss or the earth, into a newly created prison called Hell (allusions to this place are made in the Book of Revelation, as pits of sulphur and fire) where all his enemies should be sentenced to an eternal existence of pain and misery. This pain is not all physical, for their crimes, these angels, now called demons, would be deprived of the sight of God (2 Thessalonians 1:9), this being the worst possible punishment.

An indefinite time later, when God created the earth and humans, Satan and the other demons were allowed to tempt humans or induce them to sin by other means. The first time Satan did this was in the earthly paradise or Garden of Eden to tempt Eve, who subsequently drew her husband Adam into her crime. Upon their failure, as part of the punishment, the permission granted to Satan and his demons to tempt the first humans away from their Creator will now last until the end of this world for all people.

In C. S. Lewis' fictional work The Screwtape Letters a senior demon in Hell's hierarchy writes a series of letters to his subordinate trainee, Wormwood, offering advice in the techniques of temptation of humans. Though fictional, it offers a plausible contemporary Christian viewpoint of the relationship of humans and demons.

The fall of Satan is portrayed in Ezekiel 28:12-19; cf. Isaiah 14:12-14.

There is a description in the Book of Revelation 12:7-17, telling about the battle between God's army and Satan's followers, and their subsequent expulsion from Heaven to earth to persecute humans. In Luke 10:18 is mentioned how Satan fell from Heaven; his fall was probably in connection with the fall of angels as set forth in such passages as 2 Pet. 2:4; Jude 6. Pride was one of the causes (1 Tim. 3:6; Ezek. 28:15, 17). This fact may account for the expression "Satan and his angels" (Matt. 25:41). Paul doubtless refers to the fact that Satan was once an angel of light (2 Cor. 11:14).

According to Christian demonology demons will be eternally punished and never reconciled with God, as it is mentioned in the Bible. Other theories alleging the reconciliation of Satan, the fallen angels, the souls of the dead that were condemned to Hell, and God are not part of Christian demonology but the theory of the Unification Church. Origen, Jerome and Gregory of Nyssa mentioned this possibility before it was generally accepted that the fallen state is eternal, and since that time it has remained as an idea without any reason to be contemplated.

In contemporary Christianity, demons are generally considered to be angels who fell from grace by rebelling against God. However, this view, championed by Origen, Augustine and John Chrysostom, arose during the 6th century. Prior to that time, the primary sin of fallen angels was considered to be that of mating with mortal women, giving rise to a race of half-human giants known as the Nephilim.

There are still others who say that the sin of the angels was pride and disobedience. It seems quite certain that these were the sins that caused Satan's downfall (Ezek. 28). If this be the true view then we are to understand the words, "estate" or "principality" in Deuteronomy 32:8 and Jude 6 ("And the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains under darkness unto the judgment of the great day.") as indicating that instead of being satisfied with the dignity once for all assigned to them under the Son of God, they aspired higher.

At various times in Christian history, attempts have been made to classify these beings according to various proposed demonic hierarchies.

In pre-Islamic Arab culture

Pre-Islamic mythology does not discriminate between gods and demons. The jinn are considered as divinities of inferior rank, having many human attributes: they eat, drink, and procreate their kind, sometimes in conjunction with human beings; in which latter case the offspring shares the natures of both parents. The jinn smell and lick things, and have a liking for remnants of food. In eating they use the left hand. Usually they haunt waste and deserted places, especially the thickets where wild beasts gather. Cemeteries and dirty places are also favorite abodes. In appearing to man demons assume sometimes the forms of beasts and sometimes those of men; but they always have some animal characteristic, such as a paw in place of a hand (Darimi, "Kitab al-Sunnah," ii. 213). Eccentric movements of the dust-whirlwind ("zawabi'") are taken to be the visible signs of a battle between two clans of jinn.

Under the influence of Jewish and Christian demonology in post-Islamic times, the only animals directly identified with the jinn are snakes and other obnoxious creeping things. When Mohammed was on his way to Tabuk, it is said that a swarm of jinn, assuming the form of serpents, approached him and stood still for a long while.

Generally jinn are peaceable and well disposed toward men. Many a pre-Islamic poet was believed to have been inspired by good jinn; and Mohammed himself was accused by his adversaries of having been inspired by jinn ("majnun"). But there are also evil jinn, who contrive to injure men. Among these are specially conspicuous the three female demons named "Ghul" (corresponding to the Talmudical ), "Si'lat," and "'Aluḳ" or "'Aulaḳ", and the four male demons "Afrit," "Azbab," "Aziab," and "Ezb." Ghul is especially harmful to new-born children, and in order to keep her away their heads are rubbed with the gum of an acacia.

In Islam

Islam recognized the existence of all the pagan demons, good and evil, protesting only against their being considered gods. Islam divides the evil demons into five species: "jann," "jinn," "shaidans," "afrits," and "marids."

Mohammed frequently refers in the Koran to the shaidans, of whom Iblis is the chief. Iblis, probably a corruption of the name "Diabolos" = Satan, is said to have been deprived of authority over the animal and spirit kingdoms, and sentenced to death, when he refused, at the creation of Adam, to prostrate himself before him (Koran, vii. 13). The shaidans are the children of Iblis, and are to die when their father dies; whereas the others, though they may live many centuries, must die before him. A popular belief says that Iblis and other evil demons are to survive mankind, though they will die before the general resurrection; the last to die being 'Azaril, the angel of death.

Tradition attributes to Mohammed the statement that every man has an angel and a demon appointed to attend him. The former guides him toward goodness, while the latter leads him to evil ("Mishkat," i. ch. 3). The shaidans, being the enemies of Allah, strive to disturb worshipers. Mohammed, it is said, prefaced his prayers with "O God! In Thee I am seeking for a refuge from the attacks of the shaidan and his witchcraft".

Among the evil jinn are distinguished the five sons of Iblis. It was in order to keep them away that the faithful were commanded the cleansings and fumigations which are unbearable to the shaidans, who delight in dirt and filth. The pronouncing of the "takbir" formula ("Allah akbar" =Allah is very great) is also a means of driving them away. Mohammed, it is said, pronounced it in his travels whenever the appearance of the region changed, lest it might be enchanted. In later times amulets were invented to which were ascribed the virtue of protecting their bearers from the attacks of demons.

The cat plays a part in Islamic demonology. A demon assuming the form of a cat is said to have presented himself to Mohammed while he was praying (Darimi, l.c. ii. 449). Some demons assumed the form of cats (Mas'udi, "Muruj al-Dhahab," iii. 321). As to the good jinn, there are some among them who profess Islamism, and Mohammed held that many of them had listened to his sermons (Koran, sura lxxii.).

Demons in other cultures and religions

Demons are found in many religions, and many cultures have developed a rich mythology of demons. The study of demons is called demonology, while the worship of demons is known as demonolatry.

In art and literature

Many classic books and plays feature demons, such as Paradise Lost and Faust.

In role-playing games

In the Dungeons & Dragons universe, demons are known in some versions of the game as tanar'ri; these devils are hostile to the devils, who are known in the same system as baatezu. The two factions of fiends, of which there are many different subtypes of each, fight a "Blood War" among themselves. See also fantasy bestiary.

One danger of Dungeons and Dragons is that some editions employ actual symbols used by witches and magicians in summoning. TSR eliminated most references to occult symbols, demons and devils from the second edition of Advanced Dungeons and Dragons under great pressure from anti-D&D negative publicity.
